10 mw coal fired industrial water boiler co ltd
Tail gas boiler heating surface, promote energy conservation, steam boiler, make full use of surplus gas, iron and steel ring can be part of the No. 2 boiler recently implemented gas utilization upgrading the premise of low temperature corrosion does not occur. The transformation of the original two No. 2 Power Station Boiler 220 t / h circulating fluidized bed boiler, the transformation of 200 tons / hour gas-fired boiler. To reduce the cost, Shaoguan Iron & Steel ring portion can be modified in the original boiler equipment, removal coal system, discharging systems, dust removal systems, fuel systems; Lee used equipment including the original boiler water wall, drum, steel frame, platform escalators, tail shaft convection heating surface, steam systems, water systems and some electrical, instrumentation and other facilities, while adding the blast furnace, a coke oven gas in each system, the new blast furnace, coke oven gas mixing burner 4, the combustion of blast furnace gas device 4, a low-low pressure economizer, the boiler flue gas boiler guaranteed emissions compliance and four 10 kV high-pressure fan, part of the electrical and gas drainage, tail heating surface is not provided at a low temperature corrosion occurs meter facilities. No. 2 boiler after the upgrade, to ensure the boiler flue gas emissions standards and low temperature corrosion tail heating surface does not occur under the premise, as far as possible be able to mix more burning oven gas, surplus gas consumption, save energy and reduce environmental pollution.
Coal-fired boilers, fuel shots are fired, coal in the combustion chamber after the combustion heat release, the heating medium water or other organic heat (e.g., heat transfer oil, etc.) heated to a temperature (or pressure) of the thermal power plant. Coal is our energy use accounted for first, with a mature mining, transportation and sales channels, and the price is relatively low; but it also has many defects, low efficiency, resource utilization imbalance, burning emit large amounts of carbon dioxide and other harmful gases and dust, the larger impact on the environment pollution and high environmental costs.
Electrical difference between the boiler and gas boiler no real good, only for it or not. (Direct thermal electric boiler in the building standards are not allowed in the following description of an electric thermal storage boilers, there is a corresponding electric thermal storage boilers local standards) investment aspects of the common gas boiler cheaper than electric boilers at the beginning, but also the gap between the number of specific distinction, gas brand boiler size, with or without condensate recovery and technical maturity; brand electric boiler, the applicable type. Related both construction conditions, such as plumbing, gas station; selecting high and low voltage power, power distribution construction. Gas heating season in general calorific value / purity of non-compliance (even if the contract is more explicit), compared with the calorific value of the basic electrical 1: 7, the proportion of LNG to be higher, lower coal bed methane (calorific value is multiplied by the thermal efficiency of the device ). In this case, electricity savings of about 1/3 than gas, according to the grapevine, is expected this year, Liaoning low power dropped to less than 0.3 yuan (business), that electricity than the gas savings is estimated to be more than half. It covers an area of respect, if the construction of the gas gas station, then it must be a space-saving electric boiler and electric boiler is the basic module assembly, according to the actual situation; and gas boiler explosion venting port and need a certain security area. In terms of energy, electricity is no waste, waste gas, waste water, renewable energy, gas or have emissions, and fossil fuels are not renewable, although the state vigorously outsourcing, but in the long perspective, the decline in the price of more space large, but also more conducive to use, especially Valley electric. Finally, if it is 30 000 m2 of non-continuous heating conditions (such as schools, shopping mall, office, public venues, factory, warehouse, etc.), recommended to choose electric thermal storage boilers, the best choice for 10kv high voltage device, you can save some investment, and the province as well as policy. But if the area is less than 10,000 m2, the election 0.4kv low-voltage equipment is also good. Equipment and electric boilers are run automatically, without someone on duty, usually around six meters do not consider lifting frame height coefficient, the heating time can independently control these areas compared to the municipal district heating is also very advantage.
Leshan City, Sichuan Province issued a notice "Leshan City to win the Battle of the blue sky plan", the program made specific control measures and methods for the quality of atmospheric environment, as follows.
1, and strictly control the total coal consumption. Timely expansion of high-pollution fuel combustion zone ban scoping, year by year break down total coal consumption reduction targets. In 2020, the city's total coal consumption is not more than 7.075 million tons, accounting for primary energy consumption fell to below 30%. Strict control of new construction, renovation, expansion of coal projects, new coal project implementation year coal consumption reductions times the amount instead. Wutongqiao, multiple Qianwei existing administrative areas with coal-fired boilers, in accordance with the total capacity and operation of the boiler coal consumption reduction principle of substitution, central heating facilities in the new base construction of the park, but it must be stable ultralow emission standards, and to eliminate the heavy pollution weather and atmospheric environmental quality standards as a prerequisite for a stable schedule, bear autumn and winter peak load shifting and eliminate future responsibility.
2, to carry out comprehensive improvement of the boiler. Increased inspection efforts to prevent the resurgence of small coal-fired boilers. The city is not implemented before the air quality compliance and stability, a ban on new or expanded coal-fired boilers. Municipal Economic and Information Technology Bureau, the Municipal Ecological Environment Agency jointly entrust qualified units, the implementation of the transformation of ultra-low emissions, the use of coal industry enterprises to carry out at least once a major air pollutant emissions supervisory monitoring every year. Ban on new fuel boilers and other cogeneration coal, fuel oil. New gas-fired boiler construction simultaneously low NOx combustion facilities, low NOx combustion is completed before the end of December 2019, the transformation of existing gas boiler. City and county built-up areas the implementation of ultra-low emission biomass boilers transformation.
3, bulk coal use to carry out special rectification. Using coal for use in all high-quality coal, coal mines by 2020, all built to retain supporting washing facilities, the city's raw coal rate of 90%. In accordance with the principle of progressive advance of Pingba first, and then the mountains, the "coal to electricity," which, according to local conditions in key areas to promote rural villages, "coal to electricity, coal to natural gas" work. A total ban on the circulation and use of low quality coal, bulk coal investigate unlicensed business activities according to the law, high-pollution fuel combustion zone ban is abolished bulk coal sales outlets, to promote electricity instead of coal, substitution of gas for coal, to promote the use of clean coal, advanced civilian stoves . In 2020, within 30 km surrounding county town and township range of the main city of almost no bulk coal use.
4, accelerate clean energy alternatives. The implementation of "gasification of the city, alternative energy, clean alternative" projects, subsidies to change the electric boiler. 2020 non-fossil fuels in primary energy consumption should increase to more than 38%. Research to develop new energy truck traffic right of way, to encourage policies on sustainable management, new and replacement buses, rental, sanitation, postal services, commuter, logistics and other light vehicles with electric vehicles. By 2020, postal services, urban delivery, light sanitation basic vehicle for the electric car, for the van passes light logistics vehicle essentially electric cars, buses central city using all new energy vehicles and reached the country six emission standards for natural gas clean energy vehicles.
