temperature control coal fired hot water boiler

Steam boiler steam boiler price Price: works steam boiler is heated in the drum and water is converted into steam, fire gives off heat in the furnace. Qiang boiler plumbing materials sales center is located in the southern suburbs of Datong City, is a design, sales, installation and service of integrated modern enterprise management. The main environmental operating boiler, a steam boiler fired boiler, a heating furnace, steel radiators, cast iron radiators, canned motor pump, the pump piping, air-conditioning water, galvanized pipe, PP board tanks. Details can be found! Works (in Pulverized example) in the furnace pulverized coal combustion heat is first absorbed water wall heat transfer by radiation, boiling and evaporation of the water wall to enter a large amount of steam for steam separator drum (excluding the DC furnace), into the separated saturated steam superheater heated by flue gas at the top, and the horizontal flue gas flue continue to be absorbed radiation and convection, superheated steam reaches a predetermined operating temperature. Generating boilers usually equipped with a reheater is heated by high pressure steam cylinder. Reheater steam power generation is continued into the low pressure cylinder. 1, the working principle (as an example in pulverized coal fired boilers) in the furnace pulverized coal combustion heat is first absorbed water wall heat transfer by radiation, boiling and evaporation of the water wall to enter a large amount of steam for steam separator drum (except for the DC furnace ), the separated saturated steam enters the superheater heated by flue gas at the top, and the horizontal flue gas flue continue to be absorbed radiation and convection, superheated steam reaches a predetermined operating temperature. Generating boilers usually equipped with a reheater is heated by high pressure steam cylinder. Reheater steam power generation is continued into the low pressure cylinder. 2. Pulverized coal boiler operation, the position of the center of the flame will affect evaporation. Generally, low center of the flame will lead to greater evaporation, and the high center of the flame will lead to slow evaporation. Also affects the position of the center of the flame superheated steam or reheat steam temperature. Typically, superheated steam, in particular the reheat steam temperature in the lower center of the flame, and vice versa. 3. Pulverized Coal Burner front and rear walls is arranged a thrust manner, tangential firing mode, bis tangential firing methods, each method has its own characteristics. Since the above-described arrangement can not be applied in the same furnace at the same time, the influence of steam can not be directly determined.

The boiler is capable of utilizing coal, oil, gas, electricity can be transmitted to the chemical medium, the pressure vessel is converted to thermal energy or mechanical energy, has been widely used, temperature control coal fired hot water boilers and heating in industrial production is common to provide power type. Hot water boiler fuel can be utilized to heat the water to a certain temperature, or for heating domestic hot water.

In promoting energy conservation work, many of our cities have regulations limiting the city center of coal-fired industrial boilers, requires the removal of small coal-fired boilers, replaced by large-scale coal-fired central heating boiler cogeneration or fuel gas-fired boiler, which because the fuel gas-fired industrial boilers has the following obvious advantages of energy saving. 1) high thermal efficiency of the boiler. Average operating coal-fired industrial boiler thermal efficiency of only 60% to 65%, the lower the efficiency of the boiler capacity is smaller; industrial boiler fuel gas thermal efficiency is generally 80% to 85%, the thermal efficiency of the different capacity of the boiler is not very different, industrial boilers Automatic fuel gas thermal efficiency as high as 93% to 95%. See the combustion efficiency, combustion efficiency of coal-fired industrial boilers average less than 80%, the average industrial boiler fuel gas combustion efficiency of more than 95%, combustion efficiency of most industrial boilers Automatic fuel gas up to 98% to 99% (considering the flue gas condensate after the recovery of latent heat). 2) low energy consumption. Fuel gas combustion boiler generally use a slightly positive pressure, just a fan, no dust, coal, slag removal equipment, running less than half the power consumption of coal-fired boilers; small industrial boilers frequent starts and stops, since the fuel gas-fired boiler stop convenience , that is shutdown completely stopped fuel consumption, unlike coal-fired boiler shutdown device still consumes a certain amount of fuel. 3) Low fuel transportation energy consumption. Noncombustible ash coal and water 30% to 40%, ash after burning and 30% to 40% by weight of coal, half of the group receives only the oil and gas of low calorific value, coupled to the fuel conduit and gas transport, with the transport of fuel oil calorific value of coal and ash transport energy less than energy consumption 1 / 4.4) and steel boiler for producing low energy consumption. Producing fuel gas boiler steel consumption is only 40% to 60% with coal-fired boiler capacity. 5) fewer pollutant emissions. Coal contains a large amount of incombustible components, combustion ash and unburnt coal dust become, the major sources of air; and a coal ash transport, storage, and in particular the field of coal ash open field dust pollution caused by the ground; Dust , slag would cause water pollution. In general, at the same furnace heat release, smoke emission was about 11 times as coal fuel, is about 500 times the gas; of SO2 emissions from coal burning is about 3 times the fuel, gas 4000 times ; about the NOx emissions from coal burning of 3 and 4 times the fuel gas. It is estimated that the greenhouse gas emissions - a coal-fired industrial boilers of the same capacity when the CO2 emission light diesel fuel is about 1.3 times, 1.5 to 1.8 times the combustion of natural gas, city gas twice or more the burning.

We produce steam boiler is a very important part of the device, this provides a quick way to our gas steam boiler, after use, we found an excellent energy-saving effect boilers, flue gas discharge temperature is lower than the previous boiler equipment many, in line with national environmental provisions of the boiler equipment. --customer feedback
