When coal-fired boilers, which need to use technology

Coal-fired boiler is an important step to promote the process of China's energy-saving and environmental protection, many cities are very encouraged coal-fired boiler reconstruction project, giving premium policy, depending on the duration and scale of reform.

Heilongjiang provincial government to respond positively to win the Battle of Blue Sky policy action plan issued by the Ministry of ecology and environmental protection, recently issued "on the issuance of Heilongjiang Province to win the Battle of the sky three-year action plan" (hereinafter referred to as "Plan").

"Plan" requirements, as of 2020, the province of sulfur dioxide, nitrogen oxide emissions are decreased year on year in 2015 to more than 11%; PM2.5 did not meet the concentration level and above cities fell year on year in 2015 to more than 15% , and above the level of urban air quality days ratio reaches 88%, and more heavily polluted year 2015 the number of days decreased the ratio of 15% or more.

"Plan" put forward 47 specific measures from nine aspects, namely: to adjust and optimize the industrial structure, promote the formation of green development; speed up the adjustment of energy structure, build clean energy systems; actively adjust the transport structure, the development of green transportation system; optimal adjustment of land structure, promote urban and rural non-point source pollution control; strengthening regional joint prevention and control, to effectively deal with heavy pollution weather; sound regulations and standards, improve environmental economic policies; for strengthening the infrastructure, strict environmental enforcement inspectors; clear responsibility for implementation of the parties, strict accountability assessment ; strengthen information disclosure, mobilize the whole society to participate.

"Plan" requirements, strictly control the total coal consumption.

1, in accordance with the focus on the use of coal and clean use of principles, focusing on reduction of non-coal for electricity, coal and oil to promote alternative energy by 2020, cities (prefectures) Coal accounts for the proportion of energy consumption fell by 1.5% compared with 2015.

2, bulk coal strengthening control, adjustment and optimization of high-pollution fuel combustion zone ban, the use of high-pollution fuel control, bulk coal alternative strengthening. Clean steadily heating, promoting the use of clean coal and clean energy.

3, to carry out comprehensive improvement of coal-fired boilers, to carry out level and above urban area 10 steam tons / hour coal-fired boilers and "clear" action. Improve energy efficiency, we continue to implement the dual-control operations total energy consumption and intensity.

4, accelerate the development of clean energy, and orderly development of wind power, biomass power generation and actively promote the construction of hydropower development focus on the promotion of river basins, and strengthen the development and utilization of geothermal energy exploration, increase renewable energy consumptive efforts.

The role of the boiler circulating pump selection and shutters: boiler water, oxygen Why do you use water? Shutters, which is mainly used in what kind of boiler? What is the role? In addition, with regard to the boiler, what, we must know and master? These problems, the purpose is to explain and to answer, in order to solve, so, we also acquired some new knowledge so that they benefit from a lot from. 1. boiler water, oxygen Why do you use water? In addition, electric boilers burn a ton of water, heated to 60 degrees, then, is how much is the power consumption? To use the water boiler water oxygen, mainly in order to reduce the degree of oxidation corrosion in boiler systems, and this is one of its basic requirements. The electric boiler in the boiler, which burn a ton of water, then, if it is heated to 60 degrees, then its on power consumption, requires about 500 kWh.

Nanchang food factory price how much exhaust fluees temperature indicator steam boiler steam boiler plant in Nanchang food price how much? For food factory, in the production process it is the need to use steam boilers, therefore, whether it is a new food factory on a new machine or old line of food plants to expand production capacity are needed to purchase a steam boiler, for enterprises to said the cost of procurement for the boiler is the need to control, but we can not blindly control costs led to the procurement of quality is not up to the boiler, the latter, then there will be a lot of trouble.

Back to Basics: Venting for Gas-Fired Boilers | 2003-06-04

Jun 04, 2003 · As the efficiency of a boiler goes up, the temperature of the flue gases go down, and the gases are more likely to condense in the flue. When combustion efficiency exceeds approximately 83%, there is a good possibility that the flue products will condense.

Flue gas - Wikipedia

Flue gas is the gas exiting to the atmosphere via a flue, which is a pipe or channel for conveying exhaust gases from a fireplace, oven, furnace, boiler or steam generator. Quite often, the flue gas refers to the combustion exhaust gas produced at power plants. Its composition depends on what is being burned, but it will usually consist of mostly nitrogen derived from the combustion of air, carbon dioxide, and water vapor as well as excess oxygen. It further contains a small percentage of a numb

2019-8-4·Waste Exhaust Heat Boilers. Approximately 25% of the usable energy of the fuel gas is released in the exhaust of the gas engine. This can be captured for cogeneration in a combined heat and power plant. This heat exits the engine at ~450 o C as high grade heat, contrasting to low-grade heat available from the generator cooling circuits.
