gas hot water boiler for room heating

Second Session of the CPPCC National Committee Session of March 5 press conference held in the afternoon, the CPPCC National Committee of Population, Resources and Environment Committee, Democratic National Construction Association Central Committee, Environmental Management Division of the Ministry of Ecology Environment Atmospheric Liu Bingjiang said: Last year, resolve more than 30 million tons of steel production capacity, 810 million kilowatts of coal-fired units basically reached the national emission levels of natural gas, built the world's largest clean coal power base, out of 1.3 million units in industrial furnaces, coal accounts for the country's primary energy consumption the proportion of first time below the 60% to 59%, and turned off the small coal-fired boilers 23000 units.

At present the country has completed a preliminary air pollution control goals, the future will continue to promote coal-fired boilers governance, and the introduction of more stringent emission performance standards of air pollution.

Fangkuai boiler for you to sort out 30 boiler operation common problems and solutions, after learning, do not forget to share with your friends oh. (6) what are the main factors affecting the wear rate? 1 flue gas, 2 flow rate of the material, 2 particle size of the material in the flue gas, and 3 the surface shape of the worn component. The velocity of air flow is the most important factor affecting the relative direction of motion of the worn material and the wear is proportional to the third power of the velocity. 7. Why should the bed temperature be controlled between 850 and 950? 1 the ash will not melt at this temperature, thus reducing the risk of slagging 2. Higher desulfurization efficiency 3 less nitride gas in combustion gas at this temperature 4 Alkali metal in coal does not sublimate at this temperature, which can reduce slagging on the heating surface. 8, why do you have to blow the boiler pipe? Some equipment in boiler steam-water system, such as dewarming water, start-up bypass, superheater, reheater pipeline system, are not suitable for chemical cleaning due to structure, material, arrangement and other reasons. So it is necessary to use the physical method to remove the residual debris before the new boiler is put into operation, so the steam produced by this furnace is used to blow the steam-water system and equipment. 9, what are the common methods of boiler maintenance? (1) Wet protection: there are diammonium method, ammonia method, maintain feed water pressure method, steam heating method, alkali liquefaction method, trisodium phosphate and nitrous acid mixed solution protection method; (2) dry protection: there are drying method (with pressure discharge) and desiccant method. 10, which causes the deterioration of steam quality (steam pollution)? (1) steam with water. The boiler's feedwater contains impurities. The feed water is heated into steam after entering the boiler, and most impurities are transferred into the boiler water. So many cycles, the impurity concentration in the boiler water becomes higher and higher. Furnace water containing high concentrations of impurities is carried by saturated steam, which is called steam carrying water, which is called mechanical carrying. The first reason for steam pollution. (2) Steam-soluble salt. At higher working pressure, steam can dissolve some salts, which is called selective transport, which is the second reason of steam pollution.

Boiler structure and function of which types of the more popular types of biomass boilers is a boiler to biomass energy as a boiler fuel called biomass boilers, steam boilers into biomass, biomass hot water boiler for room heating, biomass stove , biomass gas steam boiler, biomass boiler vertical, horizontal biomass boilers. Classification of biomass boilers: Horizontal biomass boilers, biomass boilers vertical. Biomass Gas Gas steam boiler, biomass steam boiler, biomass hot water boiler, steam biomass gas stove. Unitary structure biomass boilers boiler consists of two parts, safety and auxiliary equipment dosing device. Boiler furnace, drum, burner, water wall, superheater, economizer, air preheater, and the furnace wall, etc. The main frame member constituting the core part of the steam production, called boiler. Boiler body is in two main parts and drum furnace. Also known as the furnace combustion chamber, fuel combustion for space. The solid fuel on to the grate, referred to as a fire bed combustion furnace Stoker, also known as fire bed furnace; solid fuel furnace liquid, gas or pulverized, is injected into the combustion chamber is called the fire chamber burner, also known as the furnace fire chamber; air coal particles burn hold it was boiling, and the furnace is inferior fuel suitable for combustion is called fluidized bed furnace, also called fluidized bed furnace; coal particles so that an air flow rotated at high speed, and strongly called fire cylindrical cyclone furnace hearth. Boiler drum main functions: The main function of the water storage drum, a steam separator, brine and water excluded pot sludge in operation, fresh air ventilator tank Axial fan centrifugal fan avoid pot containing a high concentration of salt and impurities water with the steam entering the superheater and a steam turbine. Internal boiler drum apparatus: comprising a steam separator and a steam cleaning apparatus, water distribution pipes, sewage and dosing equipment. Wherein the effect of soda is separated from the water wall by means of saturated steam and water to leave, and to minimize the steam carried fine water droplets. Low pressure boiler used as a crude flap and slit baffle separating element; above except pressure in the boiler is widely used for various types of rough separation cyclone, but also for further separation louvers, steel wire or plate or the like are vapor . The drum is also equipped with water gauges, safety valves and other monitoring and protection facilities.

How to divide the bath hot water boiler for room heating and selection class to the bathroom, then select the main boiler needs heating hot water boilers generally refers to the bathroom so hot water boiler, it probably belongs to the scope of civil boiler life. Jacuzzi bathtub boiler electric boiler, bath oil-fired boiler, gas boilers bath tub and coal-fired boilers. Baths annual major need for heating in winter and hot water, then bath boiler how to choose it? Selection 1, the number of choices bath of hot water boiler (1) is currently the best configuration choice 1 hot water boiler heating units, 1 hot water boiler with hot water for bathing. (2) selection of large hot water boiler with a plate heat exchanger. Classification bath hot water boiler and selection of the former large investment, but it is more economical to run, since the summer, late spring and early autumn does not require heating, so running a boiler to provide hot water for a bath. By increasing the plate heat exchanger, the latter method can be implemented with a double oven, small footprint, saving the original investment. 2, select the type of coal-fired boiler pollution. Most Chinese cities are prohibiting the installation and use of coal-fired boilers. Thus, other environmentally friendly boilers, such as oil-fired boiler, gas boilers and electric boilers, are still in the selection. Bath with a gas-fired boiler more economical than oil-fired boiler and electric boiler.
