Determine the location of the steam boiler room siting what issues need attention 1, boiler room refers to the building design boiler and ancillary equipment, water treatment facilities, pumps and sub-steam (water) tank and the like. Boiler should be separate and independent from other buildings. Boiler room should not be set directly in crowded places (such as public bathrooms, classrooms, restaurants, auditoriums, shopping malls, waiting rooms, etc.), or at the top, bottom, or the immediate neighborhood of the main evacuation port on both sides. 2, the new boiler room should not be connected to the house. 3, provided in the boiler room such as a semi basement layers or high buildings or the first layer must meet the following conditions: (1) each steam boiler rated evaporation does not exceed 10t / h, steam pressure does not exceed the rated 1.6MPa; rated each water boiler (including direct fired absorption chiller-room unit) does not exceed the output 7MW, the rated water temperature ≤95 ℃. (2) Each steam boiler must have a reliable overpressure protection interlocking means interlock protection device and the low water level. (3) accessories and safety interlock protection device for each boiler to regular maintenance and testing to ensure that sensitive and reliable. (4) the building structure between the boiler should have the appropriate proof Measures. (5) operate independently of the fireman who must hold the appropriate level of operating permits fireman, boiler and continuous operation of the same class more than five years, has not been an accident. (6) There must be safe evacuation routes. 4, should not be located in the boiler room or a high-rise multi-story building basement, an intermediate floor or roof, but the conditions required setting time, shall meet the requirements of paragraph 3, the first gist of the present, should meet the following conditions, and former boiler room should be set prior consent districts of the city and over special equipment safety supervision agency: (1) steam boilers rated evaporation each no more than 4t / h, rated steam pressure does not exceed 1.6MPa; each heat rated water boiler (including direct fired absorption chiller-room unit) does not exceed the output of 2.8MW, the rated water temperature ≤95 ℃. (2) must be light oil, city gas, natural gas as fuel or electric heating boiler. Underground boiler room non LPG gaseous fuel or a density greater than 0.75. Connection (3) using a fuel supply pipe welding backing. In addition, when set in the basement boiler room, blowdown or appropriate measures should be set up sewage. When using gas as fuel, the exhaust system is also provided accident. 5, not connected to the boiler room A, (B) and (C) a liquid combustible fire risk room. If connected to other production plants, application firewall separated. Waste heat boiler is not so limited. Boiler production plant belongs to class D, between the fuel tank, between the pump delivery room Class C production, between the gas regulator belonging to the delivery room A of production. 6, between the outer wall or roof of the boiler should be at least equivalent to 10% of the area between the boiler pressure relief area (such as windows, skylights, shutters, etc.), and the relief port should avoid crowded places. 7, boiler room should be equipped with emergency lighting and evacuation signs, emergency lighting voltage shall not exceed 36V.

Especially now that inflation, as the price of water, coal, natural gas will increasingly rise, while the price of electricity will become increasingly low. Electric boiler product power consumption of about 100 watts per square meter per hour. There are many responsible companies have committed to electric heating, calculated at 100 square meters house, from November 15 - ended March 15, a total of four months, electricity is not more than 2000 yuan. Ensure that the temperature 18 degrees to 22 degrees. If you use more than the normal local central heating.

Recently, located in Yan'an City, Shaanxi Province, Huanglong held removal of coal-fired boilers mobilization meeting, and promote the coal-fired boiler, "clear" work, Huanglong improve the overall air quality of the environment. The meeting was chaired by the Deputy Mayor Cao Zengjun, County Authority, Environmental Protection Agency, the Public Security Bureau and other coal-fired boilers Chaigai leading group members of the unit involved in coal-fired boilers and Chaigai of 16 enterprises and units attended the meeting.

At the meeting, urban management bureau announced the "urban transformation of coal-fired boiler demolition plan", and county coal-fired boiler demolition work arrangements for the deployment. Program pointed out, the county government before the end of June to remove their coal-fired boiler steam tons per 20,000 yuan subsidy standards in accordance with the relevant provisions of the provincial coal-fired boilers Chaigai subsidies, Chaigai completed in the first six months to the end of August unit task of tons of steam per 10,000 yuan subsidy standards, after the completion of the end of August Chaigai units should be punished to the unit in addition to the removal of subsidies, the person in charge accountable.

A coal-fired boiler Chaigai work is the key point to win the Battle of the blue sky, Huanglong is an important measure to improve the quality of atmospheric environment, the relevant units should fully understand the importance and urgency of the boiler Chaigai work, according to "own boiler demolition themselves, change themselves, government agencies take the lead in demolition, lead change, limited time limit must be removed, must be changed "requirements, implement them.

Second, the change involved units to firmly establish the overall awareness, to overcome the luck, to seize the opportunity boiler Chaigai premium policy, a reasonable choice of the transformation of the way, adhering to standards, early arrangement, early deployment, early start.

Third, the government supervises the room should work together with urban management, environmental protection and other departments, inspectors conduct regular supervision, to dismantle ineffective, slow-moving unit, to be criticized, and timely feedback evaluation to do, do you want to do a good evaluation appraisal work; County JISC to errant Chaigai, affected units and individuals county atmospheric objective assessment of the results, in accordance with the "air pollution prevention of accountability measures" be accountable, accountability, ensure on schedule to complete the work Chaigai city coal-fired boilers.

What is the main difference between a coal-fired boiler and a gas-fired steam boiler? Nominally, the obvious difference between a gas-fired steam boiler and a coal-fired boiler is that the fuel used is different. The former uses natural gas and the latter uses coal. I think the misgivings of many boiler users are why they should eliminate coal-fired boilers because many have already purchased and used coal-fired boilers. If they switch to gas-fired boilers, it will be a huge expense. Firstly, according to the development direction of China's ecological environment, coal-fired boilers will gradually be replaced by gas-fired boilers or other clean and environmentally friendly energy boilers, and gradually withdraw from the historical stage. Yes. The difference between coal-fired boiler and gas-fired steam boiler is very big, and the main reason for eliminating coal-fired boiler is environmental protection. From the fuel supply part, the gas-fired boiler only needs a pipe to connect to the boiler; the coal-fired boiler requires coal yard, coal (belt or man-made), coal transport, loading and unloading, storage and boiler loading process. It will produce dust, causing serious pollution to people's living environment. From the point of view of atmospheric emissions, the content of dust in natural gas is very small and can be negligible; the ash content of coal is high, and the ash content is about 10% and 30%, which will produce smoke after combustion. If dust removal facilities are reduced, pollutant emissions will be reduced. It will increase; if there are more dust removal facilities, the corresponding costs will increase, which is not a long-term solution. In addition, the sulfur content of natural gas is also very small, coal-fired boiler dust removal, desulfurization and nitrogen removal can be obtained, gas-fired boilers only need to consider the problem of nitrogen removal. From the point of view of other waste emissions, natural gas is basically free of other pollutants, especially urban gas. In the case of coal, coal yards, especially small boilers built mainly in the open air, will produce coal slurry water during the rainy season, seeping into groundwater or sinks. When entering the surface water, the burning ashes are transported to produce dust. Of course, there's a difference in other ways. Different. For small-sized boilers, gas-fired boilers are more energy-saving than coal-fired boilers, with simple equipment flow, small footprint, low operating and maintenance costs, and so on. These are the main differences between coal-fired boilers and gas-fired steam boilers, and the significance of eliminating coal-fired boilers. It can be seen that the use of gas-fired boilers is the general trend of the whole society.
