steam water tube coal boiler

Coal fired CFB steam water tube coal boiler technology:

In view of the possible near-term benefits, ZG recently funded an assessment of coal fired power plants equipped with three different combustion systems: Kinds of coal, Circulating Fluidized Bed (CFB), and biomass fired circulating fluidized bed. The purpose of this study was to establish, through engineering analysis, the most cost-effective performance potential available through improvement in the steam conditions and combustion systems.

The method of adjusting the temperature of the superheated steam heating stove have? The method of adjusting the temperature of the superheated steam heating stove have? DC steam water tube coal boiler steam temperature is mainly adjusted by adjusting the quantity of fuel to water. In actual operation, because the efficiency of boiler feed water and fuel heat enthalpy (depends on the water temperature) and the like will change, so the actual boiler operation to ensure the water-fuel ratio of the exact value is not easy. Coal-fired furnace will fluctuate because of the amount of coal and the amount of fuel due to the steam temperature. So, except DC boiler fuel to water ratio as the coarse adjustment means, but also must be used as a method of spray desuperheater means of fine-tuning adjustment. There is also some boiler flue gas recirculation, dampers and methods of the swing center of the flame as an auxiliary adjusting device.

To further promote the comprehensive management of coal-fired steam water tube coal boilers, Jincheng City, Shanxi Province, according to "Jincheng Blue win the Battle of three-year action plan" requirements, plans to complete 109 units of 10-20 tons of steam "small coal-fired boilers" within this year the phase-out, at the same time, Jincheng will start working out of 35 tons of steam coal-fired boilers.

This year, Jincheng counties (cities, districts) the environmental sector will urge the relevant enterprises and institutions to eliminate the basis of 10 tons of steam and coal-fired boilers on in 2018 to accelerate the phase-out and 20 tons of steam coal-fired boilers. This year, the city to complete 109 units (10-20 tons of steam boilers) working out of a total of 589.5 tons of steam boilers; at the same time, Jincheng will also speed up the foundation and 20 tons of steam coal-fired boiler out, start 35 tons of steam phase out coal-fired boilers, in principle, within the city's new domain-wide 35 tons of steam coal-fired boilers.

In addition, Jincheng will accelerate the transformation of ultra-low emission. Before the end of September this year, the city will complete 52 units (65 tons of steam per hour and higher coal-fired boilers) coal-fired heating boilers ultra-low total of 4530 tons of steam boilers transformation, and the county (city) built-up area, biomass boilers emissions transformation. After transformation, under condition of the reference oxygen content of 6%, soot, sulfur dioxide, nitrogen oxides emission concentration of these boilers respectively not higher than 10 mg / m, 35 mg / m and 50 mg / m.

Transformation of low nitrogen in the combustion aspect, before the end of October, Jincheng station 610 will complete the transformation of low-nitrogen combustion Total 1940.15 tons of steam gas boiler, after completion of the transformation, the boiler NOx emission will not exceed 50 mg / m.

10tph WNS fire tube steam water tube coal boiler project for new energy industrySteam, as a kind of energy, is widely used in all walks of life. Longzheng Environmental Protection Technologies Co., LTD. is a new high-tech enterprise applying a number of energy-saving technology including biomass molding pellet combustion technology, water coal slurry combustion technology and natural gas combustion technology to provide pure steam for food, pharmaceutical, textile and other industries. Therefore, a steam boiler acts as the heart for the enterprise; it is important for the production line that the steam boiler runs stably for a long time. The "Green Revolution" has become a global trend recently; Longzheng Environmental Protection Technologies Co., LTD. takes an active part in environmental protection, the companies decided to obsolete previous boilers with excessive emissions and introduce several sets of natural gas fired steam boilers. ZOZEN, one of the most influential boiler manufacturers in Asia, customized a comprehensive boiler solution for Longzheng Environmental Protection Technologies Co., LTD.: ZOZEN recommended 4 sets of 10 tph WNS series gas-fired steam boilers for the company based on their actual demands for steam. This series of boiler adopts a large-diameter corrugated furnace to increase furnace heat transfer area, ensuring the stable running of the boilers. In addition, the boiler is equipped with a low NOx burner to reduce the NOx emission to 30mg/Nm3; furthermore, ZOZEN also installed economizer and condenser on the tail of the gas-fired boiler, which will effectively reduce the exhaust gas temperature below 60℃ and improve thermal efficiency up to 98%.
