save energy coal fired boiler

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.

Several countries because of pressure cast iron save energy coal fired boiler efficiency indicators have been carried out in a blaze of glory roaring coal to gas work, use cast iron boiler, greatly minus the dust of the infected, and dangerous gases such as nitric oxide smoke It has been suppressed. Efficiency index is a measure of the key rules of cast iron boilers, here we come to discuss under pressure cast iron boiler efficiency indicators of several reasons. After research stakeholders, cast iron boilers heat loss stems from two main places: the loss of full combustion air ratio unreasonable and smoke exhaust heat. Heat loss can be reduced smoke emission can be converted flue gas heat recovery boiler of cast iron fitted in the tail, or selection of more excellent function FGR boiler. Fully air combustion ratio does not meet the criteria unreasonable Summary: ordinary cast iron boilers ejector burner, resulting in air-fuel ratio can not be motorized mobility. Many cast iron boilers are mechanical draft burners, resulting in an unreasonable fuel ratio because of the following: the main air-fuel ratio unreasonable case two types: when too much air, not having excessively low temperature air is heated , resulting in cast iron boiler energy costs rising, cast iron boiler efficiency index weakened; when there is insufficient air, insufficient burning situation occurs, resulting in cast iron boiler efficiency indicators weakened.

The use of gas steam save energy coal fired boiler added to give businesses what benefits? National emphasis on energy conservation increased year by year, which also contributed to the gas steam boiler flourish among industry, under the premise of environmental policies and to efficiency gains, companies are willing to choose both energy-saving, and high thermal efficiency of gas-fired boiler. Gas steam boiler in addition to providing sufficient high-temperature steam, but also can reduce fuel cost by reducing the combustion load input. The use of gas steam boiler will bring any significant benefits, let's take a look. 1, the biggest benefit is the economic use of gas steam boiler can save a lot of fuel costs for businesses, you do not need to spend lots of money to purchase a large amount of coal fuel, just use good cleanliness of natural gas will be able to output enough steam; they also do not We need the fuel storage site, only need to connect to the pipeline. 2, security is well known that natural gas is a very safe and stable, non-toxic and pollution-free, good cleanliness of fuel, liquefied petroleum gas or gas leak after not deposited on the ground, and even cause accidents will burn again. Process gas steam boiler during conveying gas selected gas is the most secure, but also easily found after leakage during use and therefore is the most secure way. 3, convenient gas steam boiler in the use, operation is very convenient, so will much favored by all walks of life. Because the use of all natural gas pipeline, a sustained run without any problems. Eliminating the need to transport coal use and clean-up or stacking cinder and other tedious work. 4. Clean the reason why gas steam boiler in the market to get a high rating, but also because it is clean and not contaminated during use, and does not produce black bottom of the pot, there is no air pollution. Thus, in use, compared to other boiler is the cleanest way.

Power plant save energy coal fired boiler working principle

Power station boilers are an indispensable device in thermal power plants. They generate high-temperature and high-pressure steam by burning various fuels (coal, oil, natural gas, biomass fuel, etc.). This steam is used to drive a steam turbine. Generator attached to the steam turbine generating electricity.

Replacing My Boiler Energy Saving Trust

2020-4-17 · Heating accounts for about 55 per cent of what you spend in a year on energy bills, so an efficient boiler makes a big difference. All well-maintained boilers burn their fuel very efficiently, but they inevitably lose some heat in the hot gases that escape up the flue (a pipe for extracting fumes and supplying fresh air to the boiler).
