"Coal to gas" birth 1 ton fired boiler with good quality 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.

When customers need to buy oil and gas 1 ton fired boiler with good qualitys, they need to know the boiler capacity that they need. Because the boiler will consume a lot of fuel during operation, the boiler capacity will cause unnecessary losses and increase the boiler cost.

Electric 1 ton fired boiler with good quality is an indispensable heating gas in winter, that is, the most important electric boiler is not suitable to place combustible materials (paper, cloth and other combustible materials) around the boiler, which can reduce the occurrence of fire from the source. 2. Electric heaters do not have plugs, plugs forget to be unplugged and resistive wires are overloaded, or aging plugs and cables can also cause fires. 3. When using electric heaters, people should always be kept on the edges, and power plugs should be unplugged when they are not in use. Many people do not have the habit of unplugging the switches, but this will also give a fire a chance of fuelling. 4. If there is a sudden power outage, Unplug the heater to prevent incoming calls A fire broke out with a sudden increase in electric current.

01. Thermal control system classification of fuel-fired gas-fired boiler (1) Electric instrument combination system mainly consists of relay, time relay, program relay and so on, which consists of program control and interlock protection system; The monitoring and regulating system is composed of electric unit combination instrument or digital and intelligent series instrument, measurement and display instrument, acousto-optic alarm instrument and so on. The design experience of electric instrument system is mature and the price is cheap, but it is difficult to realize the redundancy of the system, data transmission and maintenance, and it is also difficult to realize the advanced control method. The electric instrument system is mainly used in the small boiler, but the electric unit combination instrument is used in the closed loop adjustment. The use of cases has been reduced year by year, almost replaced by intelligent multi-functional instruments, The electrical unit assembly instruments mentioned in the following sections are simply intended to illustrate the principle and composition of the regulation system using a series of instruments familiar to the industry and widely used in that era. (2) the core of programmable control system is programmable controller (PLC). The programmable controller has been widely used in logic control at first, and the ability of process control has been increased since 1990s, which makes the application of programmable controller in the field of process control more and more extensive.

Recently, we learned, Zhangbei County, Hebei Province to speed up the transformation of low-nitrogen combustion, gas-fired, Zhangbei County Environmental Protection Agency issued the "Notice on nitrogen oxide gas 1 ton fired boiler with good quality governance", the transformation of the way around the gas boiler, the transformation of technology formalities to conduct a comprehensive explanation of propaganda, mobilization of Zhangbei above a certain size gas boiler units to actively participate in low-nitrogen transformation.

In order to ensure the smooth progress of work, the EPA developed a grasp of leadership, and a series of regular briefings on the system, arrange for the transformation of real-time tracking progress, personally led by the leaders in charge of the transformation of the construction-site supervision, to solve various problems during installation accelerate the transformation progress of the project. To date, more than 10 tons of steam Zhangbei natural gas boilers have been completed the transformation and detection of nitrogen oxide emissions, emission concentration all the stabilizing reached 30mg / m³ or less, over-done.

To protect the subsequent reconstruction work in depth, Zhangbei County township organization, the relevant units of the county with a comprehensive Mo Pai, gas-fired, gas-fired boilers for each specific model boiler unit, whether used and other basic information has been verified, the establishment improve the work ledger; to ensure that the base number is accurate, targeted work, Zhangbei arrange strengthen docking with the gas company, promptly verify the perfect new gas boiler archives, ensure the follow-up task of transformation clear, exhaustive renovation project. At the same time, combined with the actual development of the Zhangbei gas boiler compliance programs to lay a solid foundation for the comprehensive promotion of this work next year.
