electric heating steam generator supplier

Description electric heating electric heating steam generator supplier electric heating boiler convert electrical energy into thermal energy, the pressure of the water is heated to hot water or steam (saturated steam) a thermal device. It requires no furnace, flues and chimneys, and without the fuel storage site, greatly reducing the pollution caused by conventional coal-fired boilers. Electric boiler with no pollution, no noise, small footprint, easy to install, fully automatic, safe and reliable, the thermal efficiency of 98% or more other features, is a green product. Many countries in the late 1970s to the early 1980s, began to research and development of electric boiler. China in the mid-1980s, started developing electric boiler products, by the mid-1990s, many companies will be applied to electric heating boiler, central air conditioning and hot water supply. Category: Electric heating boilers are divided into three categories: LDR (WDR) electric steam boilers, CLDZ (CWDZ) electric hot water boilers and KS-D electric water boiler. Electric water boiler which is divided into KS-D electric water boilers and XKS-D electric storage water boiler. The impact of fuel: in the development process of the boiler, the type of fuel has a great influence on the furnace and combustion equipment. Therefore, not only requires development of various combustion furnaces to adapt to the characteristics of different fuels, but also to improve combustion efficiency to save energy. Additionally, technical improvements of the furnace and the combustion device further required to minimize contaminants (sulfur oxides and nitrogen oxides) in an exhaust gas boiler, coal and wood early shell boiler fixed grate, and multi-quality coal burning wood, coal and slag are added by hand. It began to grate after mechanized straight water tube boilers appears, chain grate has been widely used. Blowing wind never segmented cartridge system under development into segments blowing grate. Early furnace low, low combustion efficiency. Later, it was recognized that the role and structure of the combustion furnace volume of the furnace made high, and the use of furnace arch and secondary air, thereby improving combustion efficiency. 2, coal oil and generator power exceeds 6 MW, the size of these layers grate burner is too large, complex structure, easy arrangement, so 1920s using the burner chamber, the combustion chamber coal and oil burning furnaces . After the coal ground by the mill coal burner combustion injected into the furnace, then the capacity of the generator is no longer limited by the combustion apparatus. Since the beginning of the Second World War, almost all of the power plant boiler using the burner chamber. Pulverized early produced using U-shaped flame. Burner pulverized coal flow jetted to fall in the furnace, and then turns to rise. Later appeared cyclone burner front wall arrangement, L-shaped torch flame in the furnace. As the boiler capacity is increased, the number of cyclone burners also begins to increase, may be arranged on both sides of the wall, the back wall may be disposed on the front. Around 1930 he appeared in the four corners of the furnace and is arranged mostly circle tangential DC combustion burner. 3, after the Second World War, oil, cheap oil, widely used in many countries have begun to oil-fired boiler. Automated oil-fired boilers easily improved. After the 1970s oil price increases, many countries once again turned to the use of coal resources. At this power plant boiler capacity is also growing, combustion apparatus requires not only complete combustion, ignition stable, reliable operation, good low-load performance, must also reduce pollutants in the exhaust.

Gas heating electric heating steam generator supplier in the choice of which areas need attention construction, industrial, life most needs to heating boilers, hot water boiler then what the election or steam boiler heating? How much tonnage, how many? And how to make choice boiler energy-saving and environmental protection? these questions will undoubtedly cause great distress customer, the following solve these problems, we can do a simple discussion, consider providing some feasible ideas. A. How to determine the tonnage and the number of boilers must first be calculated from the area of ​​heating and domestic hot water heat demand of the total amount for this issue. Meanwhile, in the calculation of the process, also taking into account factors external architectural features heating areas, temperature characteristics, the peak water heating, etc., due to local conditions at the time. Then, after completing a comprehensive evaluation, will be able to consider the issue of tonnage and number of units furnace, then how should the election, which requires analysis to analyze the results of previous projects using features of the boiler, but also to figure out the actual boiler operating efficiency, as well as tonnage and heat supply matches demand real problem customer site. II. When selected gas heating boilers, steam boilers or hot water is selected by boiler application analysis of many companies, both on a simple comparison, you will find hot water boiler will be energy efficient than steam boiler, so if there are energy-saving project demand, suggested the use of hot water boiler. Of course, both need something like hot water and steam needs, you need to hotels, hospitals and other places to determine the actual situation. If a large amount of hot water heating system, requires a small amount of steam, it is recommended to install a small steam boiler or steam generator outside of the hot water boiler, in order to meet the needs of a small amount of steam. For example, a hospital or a star hotel's steam demand does not exceed 30% of the total heat demand. According to practical experience, low load operation efficiency of the steam boiler and attenuation is large, the system energy losses. Final energy efficiency is only about 60%, serious waste of energy. III. How to select energy saving gas heating boiler from the heat required systems, combustion systems, control systems and other consideration, and that is in heat transfer systems, taking into account the use of materials heat exchanger, steel, copper or iron, which according to their comparative property, currently used is copper; boiler combustion system is the key to determine whether the device is energy saving. Combustion methods currently used are: premix combustion method, atmospheric premixed combustion and the diffusion combustion method. But just in terms of energy savings, premix technology would be more advantageous, it pre-mixed air and gas, multi-mode radiator heat, the intensity of the heat transfer improved. The advantage of using this method is that the combustion flame combustion clearer, and higher thermal efficiency.

This year, Harbin, Heilongjiang Province, the financial sector to actively promote the elimination of coal-fired electric heating steam generator suppliers, and adjust the phase out coal-fired boilers financial subsidies, currently co-financing of 291 million yuan to support the city's coal-fired boilers out of work.

Combined with the characteristics of this year's work out coal-fired boilers Harbin, Harbin Finance Bureau jointly relevant departments to improve the policy adjustment, will expand the scope of the grant to build outside the area 10-20 tons of steam coal-fired boilers built-up areas and 10 tons of steam and less fuel coal boiler. Meanwhile, according to the actual situation of Harbin clean energy alternative work policies to increase financial assistance "from coal to biomass" approach; and to develop a more favorable subsidy policy of clean energy transformation of the urban fringe, the energy-saving house into the scope of the grant.

It is reported that, according to the above subsidy policy, the current urban levels, the financial capital of 291 million yuan has been implemented, which has been ahead of municipal finance district grant funds allocated 159 million yuan, 132 million yuan of the burden of the district also implemented through subsidies for local government bonds ways , effectively protecting the city out of coal-fired boilers work smoothly, since the Harbin into the winter heating period, ranked in the top 20 of 169 major cities in air quality rankings.

The electric heating steam generator supplier is important to the national economy electricity energy supply equipment, machinery, metallurgy, chemicals, textiles, paper, food and other industries, as well as industrial and civil heating boiler needs to supply large amounts of heat. Boilers using fuel combustion energy released or other energy to the working fluid (heat carrier intermediate) is heated to a certain device parameters. For heating the water to make it into the boiler steam is known as steam boilers, also known as a steam generator for heating water to make them more water into the boiler temperature, known as the hot water boiler for heating of Heat Transfer Fluid It called boiler organic heat carrier boiler. From the energy point of view, the energy conversion device is a boiler. In a boiler, a chemical energy (fuel) storage by the combustion process into the combustion products (flue gases and ash) contained some heat, then the heat transfer process by transferring heat to the intermediate heat medium (e.g. water, and steam), it relies on the heat transport device to heat. This intermediate heating medium to transfer heat energy belonging to the second, because its purpose is to provide a device capable Into energy. When the intermediate heating medium for heat conversion in a thermal power machine, the work called quality. If only the intermediate transmission to the heating medium heating device to provide heat for heat utilization, is usually referred to as heating medium. It can be divided into four categories according to their use boiler power plant boilers, industrial boilers, marine boilers and locomotive boilers. The first two categories, also known as fixed boiler, because it is mounted on a fixed basis and immovable. The latter two are called mobile boiler. This book presents a stationary industrial boilers. The boiler in three main processes: (1) the fuel combustion in the furnace, which can be released in a chemical storage form of energy, the flame and products of combustion (flue gases and ash) having a high temperature. (2) high-temperature flame and smoke for heating the working fluid (heat medium) by heat transfer. (3) working fluid (heat medium) is heated to raise its temperature of vaporization or saturated steam, or further heated to become superheated steam. The above three processes are interrelated and simultaneously, to achieve the conversion and transfer energy. Along with the energy conversion and transfer of flow and also the changes of: (1) working fluid, for example water supply (or return> into the boiler, and finally reveal the form of steam (or hot water) (2) fuel, for example. combustion of coal into the furnace, which together with the combustion of the combustible portion of the original moisture content of the flue gas into which the original residual ash is ash-containing. (3) air into the furnace, wherein the combustion of oxygen to participate in the reaction, the reaction and the excess air the remaining inert gas is mixed in the flue gas is discharged. FAW water system, a coal ash smoking system is a system of wind two three main boiler system, the work of these three systems are performed simultaneously. this typically fuel and flue gas side process (involving the combustion, heat, slag, gas flow, etc.) collectively referred to as a furnace process; the process performed by water, steam which side -1 (steam and water flow, heat, vaporization, water separation, thermo-chemical processes, etc.) collectively referred to as the pot process. the main parameters of the boiler, the boiler comprising a heat generation quantity and quality indicators of both. as the main parameters of the number of steam boilers and steam production of the steam pressure, temperature, water the main parameters of the boiler Hot water flow rate and pressure of hot water temperature.
