In October 2016, my company and the China Dunhuang International Hotel signed a ZWNSL2.1-1.0 / W-Y.Q vacuum condensing gas hot water factory direct sale condensing boiler supplier to provide heating and hot water for the hotel. The boiler implementing the response to the national policy of environmental protection requirements and local environmental protection departments on a series of low nitrogen emission standard boiler requirements, in terms of design, manufacture, installation and other sectors have strict checks to ensure that the boiler safe and stable operation.
"Coal to gas" birth factory direct sale condensing boiler supplier gas demand "from coal to gas" is one of the primary means to reduce air pollutant emissions. China's industrial coal-fired boilers, mostly without washing of coal, higher emission levels, the contribution of urban air pollution by up to 45% -65%. "Coal gas" will be replaced by coal-fired boiler, gas-fired, can significantly reduce emissions. In 2012, a number of ministries such as Ministry of Environmental Protection issued a document repeatedly requested the transformation of emissions large boiler products, such as "air pollution control in key areas" Twelfth Five-Year Plan "key projects" in the requirements, completed 2015 2841 clean energy transformation station over coal-fired boilers, which made it clear 465 coal-fired boilers replaced by a natural gas boiler. Since 2012, Beijing, Shanghai, Shijiazhuang, Lanzhou, and other places have been put forward more detailed policy requiring replace coal-fired boilers to natural gas boilers. Research shows that "coal to gas," the economy is weak, the policy is the main driving force. Due to higher gas prices, "to burn" after higher operating costs, such as coal-fired boiler and a full set of environmental protection equipment total annual cost of 661,900 yuan / (t / h), "coal to gas," the total cost of the annual 844,300 yuan / (t / h). Although a single coal-fired boilers to burn the economy is not strong, but mostly coal-fired boilers into a large gas-fired boiler feasible. Policy is the main driving force to promote the "coal to gas." It is understood that the gas boiler is facing 80 billion market demand, industrial boilers for the heavy head. According to "energy development" five "plan", "Boiler Air Pollutants Emission Standards", estimates derived gas boiler market space "Twelfth Five-Year" period about 800 million yuan, of which the industrial gas boilers for the heavy head, the market is 60 billion yuan; large gas power plant waste heat boiler to invest 150-180 billion yuan, natural gas distributed generation waste heat boiler to invest 50-60 billion yuan. According to "Natural gas development," second five "plan", 2015, China's natural gas supply of about 269.5 billion cubic meters. The demand side, China's gas power plant in 2015, distributed projects, industrial boilers totaling nearly 100 billion cubic meters of natural gas. By then sufficient air supply without worrying about gas shortage.
Horizontal pressure steam factory direct sale condensing boiler supplier efficiency of a number of cases China basically making impressive work of coal to gas, horizontal steam boiler with a very large reduces dust infected, the same time emissions of nitrogen oxides and other dangerous gases It has been suppressed. Efficiency is a measure of horizontal steam boiler critical navigation, a good number of cases began to say together to study the topic under pressure horizontal steam boiler efficiency. Through the analysis of relevant departments, horizontal steam boiler heat loss from two important parts: the full value is not ideal combustion and exhaust heat waste. Reducing exhaust waste heat should be modified in the tail horizontal steam boiler flue gas heat reuse install, or a more leading boiler condensate recovery system. Full combustion values are not substandard summarized: the traditional horizontal steam boiler selection ejector combustion engine, resulting in air-fuel ratio can not be flexibly adjusted. Many of the non-selected horizontal steam boiler burner blast automatic machines, air-fuel ratio does not lead to over several following cases: air-fuel ratio over the chance of the more important sub-2: An excessive gas stream, having a full cool air is excess heat acting , leading to increased energy use horizontal steam boiler, steam boiler efficiency horizontal weakened; when the airflow is not enough, will produce insufficient combustion, caused by horizontal steam boiler efficiency is reduced.
Compared with vertical factory direct sale condensing boiler supplier, Horizontal coal fired boiler has such advantages as long flue gas flow, slow smoke discharging speed,high heating efficiency, so it is very energy saving. The same as other boilers, the service life of the horizontal boiler depends on its right use and maintenance.
