Long Using Life Coal Fired Steam Boiler

Long Using Life Coal Fired Steam Boiler

The whole structure of normal pressure BoilerThe whole structure of atmospheric pressure boiler consists of boiler body and auxiliary equipment. The main components of boiler, such as furnace, boiler barrel, burner, water-cooled wall superheater, economizer, air preheater, frame and furnace wall, constitute the core part of steam production, which is called boiler body. The two main components of the boiler body are the furnace and the drum. The furnace, also known as the combustion chamber, is the space for fuel combustion. The furnace in which the solid fuel is placed on the grate is called a layer furnace, also known as a bed furnace; the liquid, gas or powdered solid fuel is injected into the furnace burning in the fire chamber, which is called a chamber furnace, or a fire chamber furnace; the air turns coal particles into the furnace, which is called a chamber furnace, or a fire chamber furnace; the air turns the coal particles into a chamber furnace, also known as a fire chamber furnace. It is called boiling furnace, also called fluidization bed furnace, in which the furnace with boiling state and suitable for burning inferior fuel is called boiling furnace, and the cylindrical furnace which uses air flow to make coal particles rotate at high speed and burns intensively is called whirlwind furnace. The furnace design needs to take fully into account the characteristics of the fuel used. Each boiler should burn the original fuel as far as possible. The economy and reliability of boiler operation may be reduced when the fuel with different characteristics is used.

Henan run several areas, including Henan gas boiler gas boiler operation includes several aspects: daily monitoring and adjustment operations; accident treatment; start and stop; optimal operation mode and technology improvements. When the normal operation of the boiler, the daily operation of the monitoring and adjustment of the operating accounts for the major part. "Stable" is the key, pressure, temperature, water level, negative pressure, milling parameters, etc., remain stable conditions is an important guarantee for safe and economic operation. Briefly, the steady working primarily by "balancing" the means to obtain, for example, outside the furnace combustion conditions and load balance, the pressure is stable; to balance the amount of water and evaporation, is stable water level; primer with the supply air volume the amount of negative pressure equilibrium is stable, according to Henan gas boiler operation adjustment purposes, and in accordance with the purpose of regulating the boiler operation, to take the necessary means of regulation. Daily adjustment of the key - "steam pressure." Among the major parameters of Henan gas boiler, main steam pressure to maintain stability is the key which only the steam pressure is stable, the remaining parameters to stabilize. Unstable steam pressure, steam temperature, the water level will also change, so first of all start from the pressure adjustment. Vapor pressure is divided into an outer and an inner interference disturbance, our plant, i.e. outside the external disturbance load generally little change, so change in vapor pressure are changed within the furnace i.e. interference caused by operating conditions, so holding furnace combustion conditions the stability is the stability of the vapor pressure. If the combustion conditions change, such as wind than powder, coal calorific value and other factors change, a pressure change occurs, requires us to be adjusted, thereby changing into a stable state of the combustion furnace transient state conditions.

Heating and hot water daily is an important basis for maintaining the northern region of the normal operation of enterprises; for Legal Daily organs and units, the hot water boiler is one of the indispensable energy equipment. Currently, work is facing north Heating equipment and facilities aging, increase energy conservation and environmental protection requirements and other issues. Daily logistics-related legal person responsible for improving the overall level of heating units, and the response advocated by the national energy saving, plans to purchase energy-efficient heating boiler. Considering the increasingly stringent environmental policy, Legal Daily authorities decided to use natural gas as boiler fuel. Fast boiler for 20 years, specializing in the production brand boiler, which had been successfully assisted more than Beijing enterprises and institutions, to provide clean heating. The party technical consultant fast boiler based on actual usage Legal Daily units, providing commercial condensing units 99KW vertical 1 hot water boiler.

Necessity textile mill converted to a coal-fired boiler gas boiler is a boiler equipment industry needs is more important, because a lot of links to the papermaking process requires a lot of steam drying, stereotypes and so on. However, along with the national policy of environmental protection departments to ban coal-fired boilers, and now more and more manufacturers have to use coal-fired boilers to coal-fired boilers upgrading or purchasing a new low - NOx emissions. Mills from coal to gas boilers is an important direction of the current transformation of coal-fired boilers, is one of more types of enterprise transformation, especially in the area more natural gas, coal into gas boiler is the main way. 1, in order to transform mechanization layered fired boiler gas boiler, you should first remove the front arch and a rear arch, while increasing the bottom heating surface, instead grate, grate to prevent overheating, combustion; 2, through the furnace heat transfer calculation methods determining the size of the boiler, furnace flame center position, and then pouring furnace work. In order to avoid the center position after arch boiler tubes, based on the original slope of the original arch made pipe. 3, the furnace in order to prevent an explosion, when the coal-fired boiler furnace gas is substituted, or when fuel not atomized combustion gases in the furnace incomplete combustion or heating surface of the end of the furnace, a fire or explosion occurs, should be mounting the appropriate parts of the boiler explosion vent, and to increase the ignition and flame failure protection program control to automatic control means, to ensure safe operation of the boiler. 4, is closely related to the selection and arrangement of the burner and furnace, the filling degree of the flame in the furnace should preferably not to form a dead air. Gas burner arrangement considered reasonable and piping layout, convenient operation, inspection and maintenance;

How to Run a Coal Fired Boiler at the Best Efficiency

2020-5-1·Pulverized coal fired boilers the total losses account to about 12 to 14 %. Roughly 50% of the losses can be tuned to the optimum and the other 50 % is governed by fuel properties like hydrogen in fuel, moisture in fuel and ambient air conditions. The main two losses in boiler that can be tuned by operator are carbon loss and dry gas loss.
