2000kg natural gas boilers
About condensing 2000kg boilers: major cities are now facing a wide range of frequent haze weather body, the use of new clean energy - natural gas as a heating source distributed urban heating is very important imperative way around also it has begun to implement a large area of the "coal to gas". And environmental protection and energy conservation must be combined in order to have a long-term mechanism. Natural gas condensing boiler premix gas heating than with traditional gas boiler heating heating costs can be reduced more than 30%, while the low NOx combustion techniques premix can be reduced more than 70% of nitrogen oxide emissions for natural gas efficient use of lower emissions and provides an efficient way.
What is the excess air coefficient of 2000kg boilers and boiler professionals work? Learning and understanding of the boiler, the following is mainly to answer some specific questions, which specifically is: What is the excess air ratio boiler? Its smoke is calculated, and what about? And, What are two boilers, not within the scope of supervisory inspection? Designed boiler work, which refers to what? What are the contents of their work? So, the next immediately to give a specific answer. 1. What is the excess air ratio boiler? Its smoke is calculated, and what about? Boiler excess air ratio, for the noun words, simply, is a boiler operation, the ratio between the actual and theoretical air consumption air consumption. For different types of boilers, it is not the same. For example, oil and gas furnace is 1.1, and the fluidized bed boiler, it is 1.1 to 1.2. As for the calculation of flue gas boiler, mainly related to combustion equipment type and fuel type two.
For the continuous improvement of the province's environmental air quality, enhance people's happiness index, Henan Province Government Office issued the "2019 campaign of air pollution control implementation plan." Details are as follows.
1, to carry out special treatment industrial furnaces
Based on the melting furnace, the melting furnace, sintering machine (furnace), roasting furnace, a heating furnace, heat treatment furnace, a drying furnace (kiln), coke oven gas furnace 9 categories, to carry out an intensive investigation, the establishment of industrial furnaces Details inventory management, enhance the implementation of classification regulation. Not included in the investigation of industrial furnaces list, all included in the autumn and winter peak load shifting discontinued inventory.
2, to carry out clean alternative
Of coal, petroleum coke, residual oil, heavy oil as the fuel of a heating furnace, heat treatment furnace, a drying furnace (kiln), and actively promote the use of natural gas, electricity and other clean energy and the use of plant waste heat, heating power plant and the like instead.
3, to carry out comprehensive improvement of industrial boilers
Before the end of October 2019, in addition to undertaking tasks and will not have the alternative livelihood conditions, the province's basic complete 35 steam tons / hour boiler clean energy transformation or removal of coal-fired. Transformation methods include the removal, an alternative central heating, gas coal, coal to electricity, use geothermal, wind, solar, biomass with a bag filter. Chaigai on schedule to complete the coal-fired boilers, based on 40,000 yuan / tons of steam prize money up. Forbidden to use has been shut down and eliminate waste coal-fired boilers to cash rewards and subsidies.
4, strengthen upgrading gas-fired boiler
Before the end of October 2019, the provincial municipality and county (city) district built more than 4 tons of steam and low nitrogen gas boiler complete transformation after transformation, soot, sulfur dioxide, nitrogen oxide emissions are not higher than the concentration of 5,10,50 mg / cubic meter.
5, strengthen upgrading oil-fired boiler
Before the end of October 2019, the provincial municipality and county (city) district built more than 4 tons of steam and fuel (including alcohol-based fuel) boiler low nitrogen complete transformation after transformation, soot, sulfur dioxide, nitrogen oxides emission concentration is not high in 10,20,80 mg / cubic meter.
6, vigorously promote urban central heating
Full use of existing resources and central heating facilities, the existing large-scale heat sources and central heating pipe network in the area, in-depth investigation heating demand, and promote the rich heating capacity extends to reasonable radius and root out the potential heating, heating reduce blind spots. Before the end of October 2019, Zhengzhou, Anyang, Jiaozuo, Puyang City, built-up area of central heating penetration reached more than 90 percent, Xinxiang City, central heating penetration reached more than 85%; Luoyang, Xuchang, Jiyuan City, central heating penetration reached 3 more than 80%; Sanmenxia central heating penetration 75% or more; unsealing, Pingdingshan, Hebi, 4 Zhumadian City, central heating rate of 70%; Luohe, Shangqiu, Nanyang 3 City central heating penetration reached 60% .
What are the matters needing attention in the retrofit of coal-fired 2000kg boilers?
With the implementation of the new environmental protection law and the introduction of new standards for the control of atmospheric pollution of boilers, the transformation of coal-fired boilers in various localities has been carried out in an orderly manner, and coal-fired boilers can be transformed into natural gas boilers in the actual operation. Can also be transformed into biomass boilers, but no matter how to reform, in addition to the choice of high-quality coal-fired boiler transformation company, but also need to pay special attention to the following matters.
1. When the boiler is dismantled, attention should be paid to shutting down the blower and stopping operation when the boiler is dismantled, and when the furnace temperature drops to an appropriate temperature, the boiler needs to be dismantled by the relevant parts of the existing boiler to be retrofitted to the coal-fired boiler. Stop the boiler induced fan, chain grate, then the workers enter the furnace from the fire door, remove the original furnace arch of the boiler, clean up the furnace interior, and then remove the main engine and auxiliary machinery of the boiler.
2. Attention to furnace reform is one of the key points in coal-fired boiler reform. The combustion conditions of existing boilers can be improved by reasonable transformation, which can not only accord with the combustion conditions of new fuels, but also play a better role in saving energy. However, it involves re-pouring the furnace, so special attention should be paid to keep the back arch pipe of the boiler away from the center of the flame, so that it will not be burned by the high temperature.
3. Attention should be paid to the modified boiler after a series of projects, such as retrofit of coal-fired boiler, pouring of new boiler front arch and back arch, etc., should be paid attention to after the retrofit of coal-fired boiler is carried out. One of the most important tests is to test the boiler body under certain pressure, and the boiler can be put into use only after the boiler has passed the test and revamped. These are a few things to pay attention to when reforming coal-fired boilers.
