reliable performance coal fired hot water boiler

Steam boiler overpressure phenomenon and treatment of steam boilers refers to water heated to a certain temperature parameters and the production of industrial steam boiler, the water in the steam drum is heated to become vapor, fire emits heat in the furnace, it is the principle of the steam boiler. Steam boiler belongs to special equipment, design, processing, manufacturing, installation and use of the boiler must be supervised by technical supervision departments, users only get to use the boiler permits to use steam boilers. The fuel steam boiler (electricity, oil, gas) can be divided into an electrical steam boiler, steam boiler fuel, gas steam boiler three kinds; constructed according to the steam boiler can be divided into vertical, horizontal steam boiler, steam boiler mostly small and medium sized single , double the return of the vertical structure, large steam boilers and more horizontal structure of three return. Steam boilers and boiler overpressure phenomenon processing method, the phenomenon of over-pressure boiler steam pressure ⑴ sharp rise exceeds the allowable operating pressure, the safety valve pressure gauge pointer over the red line pressure is still elevated. When the interlock ⑵ overpressure protection device operation, overpressure alarm should be issued to stop the air blowing, the wind, coal. ⑶ steam temperature rises and steam flow. 2, boiler overpressure treatment ⑴ weakened rapidly burning, manually open the valve or bleed valve. ⑵ increase the water supply, while strengthening the lower drum sewage (you should pay attention to maintaining normal water level boilers), to reduce the boiler water temperature, thereby reducing the pressure drum boilers. ⑶ safety valve pressure gauge malfunction or all of the damage, emergency shutdown, safety valves and pressure gauges are to be repaired after the boost operation. When ⑷ endanger the safe operation of the boiler overpressure occurs, the buck should take measures, but too fast buck is strictly prohibited. The ⑸ serious boiler overpressure eliminate, to the shutdown of the boiler internal and external inspection, to eliminate the overpressure caused by deformation, leakage and other safety accessories and maintenance unqualified.

Boiler boiler should be classified according to which of several energy conversion device is a way, the energy input to the boiler chemical energy, electrical energy, a boiler with a steam output of the fuel in the constant heat, high temperature water or organic heat carrier. Many types of boilers, we like how to categorize them? Here Jinhe company you explain one by one! Many classification of the boiler, the boiler can be divided according to use, can be divided according to the structure, the type of fuel boilers, but also you can press the water cycle in the form of pressure classification. It can be used as boiler thermal power boilers and heating boilers. Power boiler comprising a power station boilers, marine boilers and boiler locomotive, corresponding to power generation, marine, and locomotive power dynamic. Heating boiler comprising a steam boilers, reliable performance coal fired hot water boilers, hot tube boiler, stove and the heating medium heating furnace, to give a corresponding steam, hot water. Hot air and the heating medium and the like. Boiler by the structure, divided into fire tube boiler and water tube boilers. Fire-tube boiler, including vertical and horizontal boiler boiler, water tube boilers and water tube boilers including horizontal, vertical, water tube boilers. By species classified as boiler fuel gas-fired boiler, oil-fired boiler and upgrade technical gas boiler and gas boiler, furnace oil and gas alternative --- pulverized coal boilers, gas boilers and other dual-use. Combustion gas boiler can be divided into layers by firing boiler, in fluidized bed boilers and combustion chambers. The latest fuel alcohol-based fuel boiler, he will greatly reduce the pollution of the atmosphere of a gas boiler. Evaporation of less than 20t / h is called a small boiler, evaporation to 75t / h is referred to as large boilers, evaporation of medium-boiler referred interposed therebetween.

How to improve the energy efficiency of industrial boilers 1, focusing on the transformation of practicality (1) above to recover waste heat can be effectively used. For example: high temperature organic heat boiler flue gas, but the process does not require the production of steam and hot water, attention should be considered heated by flue gas waste heat recovery techniques combustion air. (2) improved gas boiler should focus on energy-saving technologies improve the automation level of combustion control, precise control of the combustion state. (3) Consider first the application of energy-saving technologies and sophisticated equipment. 2, considering the technical nature to further improve the thermal efficiency of industrial boilers, it is necessary to consider new energy-saving technologies and equipment. Advanced (1) energy conservation technology and equipment, difficult to implement. Such as: waste heat recovery heat exchanger and the new technology: heat pipe technology, the condensed waste heat recovery technology; new water treatment device: microbial fouling and electromagnetic processing techniques (e.g., hydraulics); combustion automatic control technology. (2) spraying pulverized coal combustion technology (stratified combustion mode and suspension-fired boilers) design, construction and operation of high demand management, oxyfuel technology, such as high temperature air combustion technologies require large investments. 3, forming a complete transformation handle (1) must be considered boiler energy saving, heat insulation of synchronization is complete, sealing, and improved methods of burning fuel adjustment, and the fuel air distribution system of the inverter, reduced nicotinamide tube improved resistance to treatment. (2) pay attention to clean the boiler heating surface, and providing technical improvements boiler water, slag, ash, etc., to ensure that the boiler has good heat transfer properties. (3) the necessary training for technical operations and daily management of energy-saving equipment.

In order to further standardize Xuzhou City, air pollution control construction and operation management, protecting and improving the quality of the environment, prevent environmental pollution, introduced the "Xuzhou City in 2019 the thermal power industry, air pollution control basic norms." For the raw fuel storage, handling, transportation, storage byproducts, transport, collecting and centralizing the flue gas treatment systems and other aspects of the essence of the specific requirements.

First, all coal-fired units desulfurization facilities required to install, in addition to coal-fired circulating fluidized bed boiler units to be installed denitration facilities, coal and biomass fuel units to be equipped with efficient dust removal facilities. Desulfurization, denitrification, dust removal device processing capabilities must meet the production needs, we must be able to maintain long-term stable operation, must be professional manufacturers design, produce qualified products. Exhaust pipe shall be provided with permanent sampling ports and in accordance with national and regulatory requirements related to the construction of Jiangsu Province.

Second, the boiler produces air pollutants must be in accordance with national standards and requirements related to Jiangsu Province, construction of flue gas collection systems and centralized purification facilities, flaring has been the implementation of "coal to gas," "dry FGD" and included in discontinued closure plan outside the coal boiler, and the rest are required to install the cooling and dehumidification systems, and to ensure proper operation.
