About Henan low nitrogen gas china corner tube coal fired boiler and the transformation of Henan low nitrogen gas boiler is upgraded on the basis of common furnace on it than the ordinary boiler biggest advantage is that the emission of nitrogen oxides. Henan low nitrogen gas boiler is divided into two: one is nitrogen oxide emissions below 80 mg; the other is a nitrogen oxide emissions below 30 mg. Of course, if you want to achieve low nitrogen emissions, it must be met is to use low-nitrogen burners. From the development trend, Henan low nitrogen gas boiler into the mainstream as a winter heating, natural gas is not only energy efficient, low-carbon environment, the country can meet the heating needs of sustainable development and environmental protection are two simultaneous, consistent with the development of the cause of energy conservation ideas , winter heating will become mainstream products in north and south China regions. In response to the national "energy saving" the call, further reducing boiler NOx emission from the country are carrying the boiler to Henan low nitrogen gas boiler. Currently, low-nitrogen transformation technology boiler there are three: First, the two-scale low NOx combustion technology, mainly for Corner Tangential unit, by controlling the scale of the transformation process and on the spatial scale to achieve three characteristic difference, resulting in two furnace three beneficial characteristics forming the anti-slag, the NOx is low, steady combustion of the scale function. Second cyclone low NOx combustion technology, primarily for the opposed wall units, by replacing coal burner and the transformation of secondary air, tertiary air boiler to reduce the nitrogen oxide content. Third W low - NOx combustion flame technique, the longitudinal arch boiler pulverized coal burner to a low NOx combustion is replacing a specific structure, to reduce the impact on the normal operation of the combustion tissue as possible, the structure of the secondary air substantially constant. These three low NOx combustion technology in the transformation have made good Jiangdan effect. Now, there are many small boiler (100MW units and below, primarily in the form of Tangential) also need to be low-nitrogen transformation, but if using conventional low-nitrogen transformation technology, investment costs are relatively high for small boiler is concerned, may not be bear, economic efficiency will also be affected. In view of this situation, we launched a small-scale low-nitrogen transformation technology boilers, control and transformation through major processes affecting boiler nitrogen oxides produced with a smaller cost of renovation to achieve the purpose of significantly reducing the concentration of nitrogen oxide emissions boiler.
Treatment of natural gas leakage in horizontal gas china corner tube coal fired boiler room
According to relevant data, with the speeding up of changing coal to gas, the project that change industrial coal-fired boilers to industrial gas boiler no matter in quality or quantity are growing faster. In addition to the support of national policy, the development of industrial gas boiler also benefited from the convenience of natural gas.
When coal-fired china corner tube coal fired boilers, four matters requiring special vigilance: the highly polluting coal-fired boilers transformation process, can be said boiler industry mainstream major event. General common is the transformation of coal-fired furnace gas-fired boiler, the coal to change the high fuel costs, as well as on the environment caused serious pollution problem, not a small project, you need to pay attention to the transformation of every aspect of a good safe and effective boiler close with, in order to avoid a failure of the transformation occurred. 1, the original boiler boiler before carrying out the demolition work will require the original host and auxiliary boilers were removed, concrete demolition work carried out by professional staff, in order to more quickly complete the demolition work, but also to prevent the removal process after the accident 2, note that the boiler pressure capacity of some small coal-fired boiler into a gas-fired boiler, also changed the original state of combustion, combustion becomes negative as positive pressure combustion; this process requires special attention throughout the furnace wall the structure and sealing, the sealing function properly may cause the boiler could not withstand the pressure due to the transformation, and accidents. 3, furnace renovation precautions in many cases will change when coal gas, because of poor atomization or incomplete combustion of fuel remaining in the furnace, the slightest mistake will cause fire or explosion; it is to be in the transformation is complete installed in the appropriate parts of the blast doors to prevent the explosion accidents; while additional ignition and flameout protection device to ensure the safe operation of the boiler. 4, after the transformation is complete when the test is completed after the transformation of the boiler, also requires complicated testing to confirm their safety test method is commonly used for the transformation boiler high pressure stress tests, the test and reached after the use of standards, it is considered as completed the transformation boilers.
Recently, Shandong Province, issued a "thermal power plant air pollutant emission standards (DB37 / 664-2019 instead of DB37 / 664-2013)". Standards will be implemented on September 7, 2019.
First, the standard applicable to the use of a single output 65t / h or more layers in addition to coal-fired burner, furnace stoker boiler or steam generator; single output 65t / h or more oil, gas, or steam generation boiler; single output 65t / h or more power using steam boilers other fuels; pulverized coal fired boilers of various capacities; various capacities gas turbine. Gas turbine integrated gasification combined cycle power generation is performed in this standard gas turbine exhaust gas as a fuel limit.
Environmental Impact Assessment II. This standard is applicable to the existing project management of emissions of air pollutants, as well as the above-mentioned new construction, renovation, expansion projects, environmental protection facilities design, environmental protection facilities acceptance, pollution permits and air pollutants after putting into operation emissions management.
