Coke oven gas power plant boiler

What is the difference between a gas-fired coke oven power plant boiler and a coal-fired boiler?

Both gas and coal can be used as fuel for boilers, but different types of boilers are named according to the types of fuels used, so there are gas boilers and gas boilers. So what is the difference between a coal-fired boiler and a gas-fired boiler, apart from the fuel used in combustion?

1. The fuel used by different coal-fired boilers to exhaust smoke is coal. When coal burns, it will cause serious pollution to the environment by producing larger smoke and dust. However, high-stability gas-fired boilers do not emit black smoke after combustion. Because gas can basically be completely burned, smoke-emitting black poison can reach zero level, the content of SO2 in it is very small, so there is no pollution to the environment.

2, heat loss is different in order for coal-fired boilers to maintain adequate combustion intensity, the use of human or other equipment to constantly add coal to the furnace, when the need for intermittent operation, It takes a long time to raise the temperature in the furnace when starting again, so it will produce great heat loss when pressing fire, and the gas-fired boiler is very convenient to start and stop, and can heat up rapidly during intermittent operation, so as to reduce the heat loss in this process.

3, the different ways of treatment after combustion will produce a large amount of ash after burning in the boiler. In order to maintain the health of the environment, the ash will be transported to the professional slag removal yard for treatment, but gas is used in the gas-fired boiler. There will be no residue after combustion, so there is no need to deal with it. It not only avoids the pollution to the environment, but also reduces the labor intensity of enterprises and the storage and transportation of urban ash.

Recently, the State Administration of China's market, the National Development and Reform Commission, Ministry of Ecology Environment jointly issued the "Notice on Strengthening Environmental Protection and Energy coke oven power plant boilers" (the "Notice"), put forward specific requirements for environmental aspects of energy-saving boiler work.

"Notice" the implementation of the guidance, "the CPC Central Committee and State Council on the overall strengthening of environmental protection and resolutely fight tough fight pollution prevention advice" and other documents, adhere to safety first, prevention first, the five principles of energy saving, comprehensive management implement energy saving boiler from the production, import, sale, use and other aspects of business to post the main responsibility, and strengthen supervision and management of Eng environmental Protection in the "special equipment Catalog" range of boilers, and comprehensively promote energy-saving environmental governance boiler.

First, across the country, in principle, to a new 10 steam tons / hour of coal-fired boilers and, in key areas (and the surrounding areas of Beijing, Tianjin, the Yangtze River Delta region and Fenwei plain) and the rest of the city built the county level and above New District, in principle, to 35 tons of steam / hour of coal-fired boilers.

Second, the new coal-fired boiler emission concentration of air pollutants key areas need to meet ultra-low emission (6% on the basis of the reference oxygen, soot, sulfur dioxide, nitrogen oxides emission concentration of not more than 10,35,50 mg / m) requirements.

Third, the area reserved execution key boiler air pollutant emission limits or special places more stringent emission standards, 65 t steam / hour coal-fired boiler and above all of the ultra-low emissions and energy transformation embodiments, a low nitrogen gas boiler is substantially complete transformation.

"Notice" also stressed the upgrade boilers with energy and environmental conservation requirements. Boiler units to implement the main responsibility for ensuring that the boiler energy efficiency and emissions of air pollutants meet legal regulations, technical specifications and requirements of the relevant standards in China.

Fourth, for the boilers do not meet environmental requirements, and use shall take appropriate measures for improvement, if after rectification not meet the requirements, be allowed to continue to use.

Fifth, the boiler unit to apply for emission permits in accordance with laws and regulations, and to establish their own monitoring system, strict discipline and preservation of the environment management accounting, timely and relevant departments to prepare and submit emission permits implementation report.

Sixth, the boiler unit to promptly take the initiative to report the boiler equipment obsolete, and apply for cancellation of the boiler use registration shall not be obsolete boilers to move equipment or put into use again.

WNS is automatic gas (oil) parameters commonly used coke oven power plant boiler. Where each letter implication is that

W: horizontal. A boiler according to the design and installation of the outer layout, was lying state. An exhaust gas stream produced by the boiler is of horizontal flow, the flow of hot gas, in the same section on the exhaust gas temperature is low compete.
