coal fired electric utility boilers

Power plant coal fired electric utility boilers working principle

Power station boilers are an indispensable device in thermal power plants. They generate high-temperature and high-pressure steam by burning various fuels (coal, oil, natural gas, biomass fuel, etc.). This steam is used to drive a steam turbine. Generator attached to the steam turbine generating electricity.

According to the central environmental supervision feedback on the issues raised in item 50: "Mudanjiang 108 wood processing enterprises, 69 there is the issue of illegal construction projects, companies supporting more than 114 coal fired electric utility boilerss for small hand-burning stove, black smoke very serious people to report complaints, "the rectification of the problem. Mudanjiang City, Heilongjiang Province, the municipal government attaches great importance to conduct a comprehensive renovation work for small coal-fired boilers.

The beginning of tasks to carry out, Municipal Environmental Protection Bureau of Mudanjiang City Center 108 existing wood processing enterprises in coal-fired boiler equipment to be checked. Inspection and found 69 illegal construction projects there is a problem, companies supporting more than 114 boilers for small hand-burning stove, black smoke is very serious. To date, there are 65 companies to complete the record, four enterprises waste industry. By Trade and Industry Bureau of Quality Supervision and verification, 114 sets of small boilers of this regulation in the wood enterprises, has completed the transformation units 62, cancellation, revocation 23 units, idle shutdown, waste industry 26, and removal of three. Wherein Yangming boilers zone 97 (where the 58 transformation is complete, the boiler cancellation, revocation table 21, the idle shutdown, industry waste boiler 18); boilers zone 12 (where the grid and transformation of the two, the idle shutdown the six, cancellation of Taiwan, has been demolished three); Dongan District 3 boilers (in which the transformation is complete for two, small boilers cancellation Taiwan); Xi'an area, Edmonton area each in Taiwan, the company has waste industry.

Next, the relevant departments will conscientiously implement the municipal government on Ecological Construction Decision deployment environment, learn from experience and practice fraternal units, work together to tackle, wood enterprises continue to consolidate and expand the results of pollution remediation, pollution prevention and determined to win the battle , to create the sky bluer, more green mountains, clear water and more beautiful environment, Mudanjiang modernization and make due contributions.

What are the common type gas steam coal fired electric utility boilers have? Common types of gas steam boiler is as follows: fuel (gas) is oil or gas as fuel, burning the fuel using a burner to heat the gas as steam carrier. Structure is generally divided into two kinds of vertical, horizontal, mainly based on these two forms of device space height. Gas based on coal as fuel, gas and steam as a heat carrier. Hand generally divided into vertical burn, horizontal cylindrical type, three kinds of gas fired horizontal plane structure, mainly based on labor intensity stoker thereby form these three points. For electric heating electric heating oil furnace, heat is generated and transmitted by the electrical heating element is immersed in the gas and steam to steam gas medium by the circulation pump to force liquid recycle gas steam, with a heat transfer to or more heating equipment, heating equipment after unloading, re-circulation pump, back to the heater, and then absorb heat, heat transferred to the device, again and again, to achieve a continuous heat transfer the temperature of the heated object rises, the heating to achieve process requirements.

Cofiring biomass in coal fired coal fired electric utility boilers

Cofiring biomass in a coal fired boiler is like a cart drawn by a horse and a mule. What are the advantages? It took millions of years for decaying organic matter to form into coal. Biomass on the other hand is organic matter that is only a few days old. The composition and characteristics of biomass is different from coal and makes cofiring biomass and coal difficult.
