2 ton industrial coal fired central heating boiler
Recently, in Jiaxing City in Zhejiang Province Nanhu District, officially launched a comprehensive investigation and action on gas 2 ton industrial coal fired central heating boilers and biomass boilers urban built-up areas, and actively promote the transformation of low nitrogen emission gas-fired boiler, Zhejiang Province, determined to win the Battle of the sky made own contribution.
According to the requirements of the investigation, the South Lake district towns, streets, parks within the jurisdiction of the respective gas boilers and biomass boilers urban area to take home from house to house visits Paimo way, the ecological environment Branch area combined with market regulators issuing a list a verification form inventory management. After the statistics were found in the region with gas boiler 35 units, built-up area of biomass boiler Taiwan.
Meanwhile, Nanhu District will be in more than 500,000 cubic meters of natural gas consumption in the four on-site visits to enterprises as a pilot enterprise low nitrogen transformation operations boilers, ecological environment Branch area of personnel, publicity reform provinces, municipalities and low nitrogen emissions on gas-fired boiler requirement that the premise of ensuring safety in production, natural gas boiler NOx emission after the transformation shall not exceed 50 mg / cubic meter, and listened carefully to the enterprise raised about the difficulties of combustion gas boiler low nitrogen transformation exists.
To speed up the investigation and major renovation large boilers, Nanhu District definite time node, before the end of 2019 business model will complete the transformation of low nitrogen gas boiler, at the same time, the city built-up area of biomass boilers implement ultra-low emissions transformation. Nanhu District will adhere to routine inspections and investigation focused on the combination of concentration and control checks and unannounced visits to combine law enforcement when combined with the daily supervision and wrong, and the law enforcement inspection report from the masses combine to ensure long-term monitoring of boiler regulation implemented.
Coal fired CFB 2 ton industrial coal fired central heating 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.
Steam 2 ton industrial coal fired central heating boiler heating in winter north of the advantages and disadvantages of our country, cold weather, heating is essential, often used before coal-fired boilers for heating, but coal-fired boilers to serious air pollution, now gradually replaced by steam boilers. Steam boiler is also very common type of heating equipment, are now gradually penetrate to the south. Steam boiler heating both advantages and disadvantages, we compare: first, an analysis of the advantages of using pulverized coal combustion boiler, the coal is in fact relatively high temperature, the surface temperature of the steam boiler is relatively rapidly increased, but in fact, this system can withstand particularly low cooling system. 2, the steam in the evaporation process, as in fact it is the gas density is quite small, for which the net pressure steam boiler itself is relatively small. 3, the steam itself does not require any external pressure resistance of the propulsion system for it. 4, steam boiler has a clear advantage, the heating effect and very fast, but it stopped gas speed is faster, especially for users of intermittent heating. Second, an analysis disadvantage, during use in a steam boiler, because the pipe is relatively high stability, and is not easy to heat, in the course of prolonged use, the dust around the surface of the device, so that the relatively poor surroundings, and heat slowly dispersed, easy to burn people. 2, in a more simple production conditions, the use of the boiler does not care, and the system will cause leakage particularly large heat loss, so that the waste of energy is relatively more serious. The disadvantage of steam boilers we could have been avoided, in use of the process will be seriously careful to avoid being burned or wasted energy.
Chemical plant 2 ton industrial coal fired central heating boiler combustion efficiency improvement measures which are not high chemical plant boiler combustion efficiency is not high improvement measures what? The low-temperature exhaust gas boiler combustion efficiency test, a higher excess air ratio, suggestions for improvement higher problems: 1, the excess air ratio due to lower general, industrial boilers was 1.4. Due to the different internal structure of each of the boilers, excess air coefficient can be adjusted according to the actual operation, there are sufficient coke burn time in the boiler. Additionally, secondary air may be suitably provided, coke sufficient oxygen for complete combustion, reducing the incomplete loss of solids. 2, due to lower exhaust gas temperature of the boiler exhaust gas temperature account for a large proportion of the boiler heat loss, so the loss of the boiler must be minimized. In one aspect, the dew point should be to prevent corrosion; the other hand, the exhaust gas temperature is not so high. 3, to improve the uniform distribution of air to the boiler furnace combustion efficiency, so as not to cause incomplete combustion of the coal formation dead. As the pilot were grate boiler, the moving speed of the chain should be controlled within a reasonable range of coal on the grate have enough time to complete combustion, but not too long so as not to waste grate. In addition, high-volatile coal, the coal should be possible to improve the quality, to shorten the combustion time, reduce the loss of solids of incomplete combustion.
