Gas central heating costa rica fired boiler manufacturers: For a long time I had coal resources are a big country, according to the relevant department statistics national energy use of coal in energy utilization percentage of 70%, the data currently in the world in terms of only four countries is the case (DPRK , Poland, South Africa, China), we can say more than half of the region are due to sub-state pollution, and therefore to change this situation for the benefit of our children and grandchildren is the only solution! This occurs when the fuel gas-fired boiler is that we, step by step out of China's haze cited under the lights, fuel gas-fired boiler is to gradually shift our energy agency oil, gas from coal, clean fuel raw materials such as fuel booster.
Combustion conditions provides rapid and substantially complete combustion of 1, a relatively high furnace temperature: the chemical reaction is the basic condition of combustion, fuel ignition and stable combustion, burn have a significant impact, maintaining a suitably high temperature furnace to important. Of course, when the furnace temperature is too high, consider the problem of slagging costa rica fired boiler manufacturers. 2, the air supply amount: the amount of air supply, is to provide enough oxygen for the fuel, which is the original conditions of the combustion reaction. Air supply, fuel not get enough oxygen, it can not achieve complete combustion. But excessive air, the furnace temperature will lead to loss and exhaust loss increases. 3, good mixing conditions: Mixing is an important physical conditions of the combustion reaction. Mixing the hot flue gas in the furnace is heated to reflux of the pulverized coal flow, so as to rapidly fire. Mixing in the furnace is strongly perturbed stream to provide oxygen to the soot combustion stage surface, outward diffusion of carbon dioxide, and to promote post-combustion of the fuel burn, it is an indispensable condition. 4, enough burn time: the fuel in the furnace for a time sufficient to achieve a high degree of fuel burn, which requires a large enough volume of the furnace. Proportional to the volume of the furnace and boiler capacity. Of course, the furnace volume is also characteristics of the fuel combustion, easy to burn fuel, furnace volume can be relatively small. For example, the same capacity of the boiler, furnace volume of fuel than pulverized coal furnace is small, and vanished without burning furnace volume than coal burning bituminous coal furnace volume slightly larger.
Comparison of coal-fired steam costa rica fired boiler manufacturer and gas steam boiler? Which is more cost-effective? There will be new users are asked coal-fired steam boiler and gas steam boiler which is more cost-effective in a number of economic operation? Believed to be ready to buy a steam boiler of every business relationship or personally, with you today, I will work together to analyze these two boilers in operating costs to do a comparison. First, the first point to analyze procurement costs: Because gas steam boiler in the annex above techniques and configurations to be clear lead and coal-fired steam boiler, gas steam boiler supporting a dedicated burner, put the cost of just one burner price opened, so that the same tonnage of steam boilers, steam boilers high gas prices than coal-fired steam boilers and more. The second point to analyze construction costs: The costs mainly from the boiler room, boiler tubes of steam investment funds. Where the coal-fired steam boiler because more appropriate auxiliary equipment, so in the boiler room construction funds to be more. There is a gas steam boiler automatic control operation, and automatic alarm and automatic protection function. Connected to the gas pipeline, the burner will automatically supply costs can effectively save staff. Coal-fired steam boiler because of the need of coal on the program, so in terms of personnel expenses wage will be larger. The third point to analyze the environmental cost: major review means that the coal-fired steam boilers now more stringent. The gas steam boiler due to the operation of the economy, environmental protection and energy saving, as well as government policy to encourage more and more widely used. The fourth point to analyze the cost of fuel: coal-fired steam boiler will be much higher than the steam boilers in gas fuels. After analyzing the above four points of view on coal in order to save operating costs more than gas steam boiler steam boiler, but coal-fired steam boiler steam boiler environmentally friendly than gas in environmental protection, environmental pollution is now increasing in recent years, so the state to environmental pollution control is relatively strict, so in accordance with the requirements of environmental protection point of view has an advantage gas steam boiler.
Recently, Shandong Province, issued a "thermal power plant air pollutant emission standards (DB37 / 664-2019 instead of DB37 / 664-2013)". Standards will be implemented on September 7, 2019.
First, the standard applicable to the use of a single output 65t / h or more layers in addition to coal-fired burner, furnace stoker boiler or steam generator; single output 65t / h or more oil, gas, or steam generation boiler; single output 65t / h or more power using steam boilers other fuels; pulverized coal fired boilers of various capacities; various capacities gas turbine. Gas turbine integrated gasification combined cycle power generation is performed in this standard gas turbine exhaust gas as a fuel limit.
Environmental Impact Assessment II. This standard is applicable to the existing project management of emissions of air pollutants, as well as the above-mentioned new construction, renovation, expansion projects, environmental protection facilities design, environmental protection facilities acceptance, pollution permits and air pollutants after putting into operation emissions management.[email protected]
