Coal Steam Heat Boiler
Select the first steam coal steam heat boiler to know what parameters? Steam boilers have the following main parameters: 1, Rated evaporation Rated evaporation is power steam boiler, steam boiler is the most important parameter, usually expressed in tons evaporation, that is, we usually say how many tons of boiler. 2, rated steam pressure rated steam pressure means that the steam pressure generated in the steam boiler, generally expressed in MPa or kg. 1MPa is 10 kg, like laundry, all hospitals, factories and the like conventional steam occasions the general use of low-pressure steam 1.0MPa or less. Only when using steam as a power to require the use of high-pressure steam. 3, where the steam temperature of said steam temperature, refers to the temperature of saturated steam. Saturated steam pressure and steam temperature are corresponding. Temperature of saturated steam at a pressure of 1MPa 184 ℃. 4, gas / oil / coal consumption fuel consumption is an important indicator of concern when choosing a steam boiler, which is directly related to the use of the running cost of the boiler. In the operation of the boiler, the fuel cost is very impressive, if just considering the purchase cost of buying a cheap but high energy boiler, which led to the late high operating costs, certain that it will be wasted. 5, the thermal efficiency of fuel consumption with the boiler thermal efficiency of boilers is inversely proportional. The higher thermal efficiency, lower fuel consumption of the boiler. Boiler thermal efficiency expressed as a percentage, the value is a more intuitive. 6, the boiler operating weight, size or location in the election of the steam boiler, it should find the place whether the load per unit area can withstand the weight of the steam boiler, and if there is enough space to place the steam boiler maintenance and reserve space.
Diqing in Yunnan Nonferrous Metals Co., Ltd. mainly engaged in Pulang copper mining, site selection, sales and other items. As we all know, in the copper smelting process, it consumes a lot of electricity and thermal power resources, which account for most of the hot water consumption. Combined with the actual demand Diqing company, to provide fast Boiler 1 stage electric heating hot water coal steam heat boiler of 2.1MW.
Gas-fired steam coal steam heat boiler and gas steam boiler at any time there is any good compared to the country more and more attention to environmental protection, gas steam boiler has been a great blow, and relatively gas steam boiler by many users of all ages, in recent years, the country also strongly promote the use of gas-fired boiler, gas steam boiler then compared with the gas steam boiler what good is it? And today we work together to explore. Gas-fired steam boiler steam boiler and gas each accounted for half of the market, showing potential rival, but in the long run, gas steam boiler will obviously be the only dominant market. Do not believe, look! 1. Purchase costs: gas boiler is evident in the technical and auxiliary facilities are far ahead of the gas boiler, and it is equipped with a special gas burner. 1 steam boiler tonnage, for example, the price of gas than the gas boiler boiler on high about 30%. 2. Construction costs: The costs mainly from the boiler room. Because the corresponding auxiliary equipment more gas steam boiler, the boiler room in the building have a little more money. The gas boiler auxiliary facilities require little or automatic control and operation, and automatic alarm and automatic protection, not only save building costs, but also safe and reliable; Also connected to the gas pipeline, the burner will automatically supply gas can effectively save costs staff. The gas-fired boilers because of the need of coal on the program, so it needs some staff payroll. 3. Fuel cost: around this by looking at the actual specific fuel price can be clearly seen. The fact is that the amount of gas than the gas burned per hour for much more. 4. environmental costs: in the need to protect the environment, review the current gas boiler more strict. 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.
Distinction gas steam coal steam heat boiler and a conventional coal-fired boilers and gas steam boiler (1) in a conventional coal fired boiler should be prechamber through grinding equipment, coal should be produced for combustion injected into the furnace, the entire combustion process in furnace and in the form of a suspension. (2) as long as the gas steam boiler biomass fuels open, dried and crushed, the helical feeder to the air before it is blown into the top of the combustion grate vibration. After burning the soot removed from the baghouse gas steam boiler. 2, different air supply preheating. Gas-fired steam boiler burner underlying mode, two-pass configuration, the fuel combustion, the boiler operation is stable and take up less space, while the spoiler is inserted smoke tube, smoke slow speed, increase heat transfer, a high thermal efficiency, reducing user fees (1) coal-fired boiler air preheater flue at the bottom, below the economizer; using flue (2) temperature of the air supply end of the cigarette is heated, different from a conventional boiler, the feed gas steam boiler air preheated by the air preheater flue gas cooler and the two parts to feed water as a medium to absorb heat of the flue gas, conveying air into the furnace. Warm air supply system for a gas steam boiler is controlled by adjusting the supply air temperature of the heating water flow can be provided by adjusting the electric charge of the bypass track circulation water through the valve and the air preheater flue gas cooler bypass control. Water heat exchange section, cooling water heated through the air preheater and the cold air delivery fan; then, this part of the water continues to flue gas cooler, flue gas by exchanging heat with water in the flue gas cooler, water heating, cooling the flue gas. In the bypass, a bypass flue gas cooler and another bypass air preheater, both have their own electrical control bypass and isolation valves. When the flue gas cooler exit gas temperature is too low, the bypass isolation valve is opened, water does not pass through the flue gas cooler, flue gas heat exchanger is not performed to ensure the flue gas cooler outlet gas temperature is not too low smoke corrode gas cooler. In order to enter the flue gas cooler feedwater temperature is not too low, when the air preheater outlet water temperature is below a certain temperature, it opens the bypass, supply cool air can not be heated, the water temperature is too low to prevent the influence of the flue gas cooler work . But also to ensure the temperature of the flue gas through a gas steam boiler precipitator. 3. The coal-fired boiler flue gas fired boiler bag filter should be used for desulfurization libraries to ensure the emission of pollutants lower than the standard. Steam boiler is an energy conversion device, the energy input to the boiler fuel chemical energy, electrical energy, thermal energy and other forms of high temperature flue gas, and after converting the boiler, the steam output having a certain outside thermal energy, high-temperature hot water or an organic carrier. Gas hot water boiler with environmental protection, energy conservation, safety, salient features fully automatic operation, and ease of use. In addition, due to the operation of the economy, government policies to encourage, gas hot water boiler more and more people of all ages. However, biomass combustion flue gas are different. Biomass fuel of low sulfur and nitrogen content, only through the biomass filter before discharge into the atmosphere. However, the carbon content of fly ash produced by the combustion of biomass, coal-fired boiler boiler efficiency is better, but the carbon dioxide content in the greenhouse can be reduced. Under the same nitrogen content of the fuel, the nitrogen oxides emission concentration of boiler far below the emission standards for coal-fired boilers. The problem should be noted that operation of the gas boiler. From the operational perspective view of the gas boiler, the operation of the gas boiler should note the following: The actual fuel consumption of the boiler operation, the amount of oil to the adjustment screw feeder. Unburnt fuel in the furnace, induced draft fan and the blower can not be stopped. Sudden power outage in operation, must be promptly removed fuel furnace. Not add biomass fuel before the shutdown. When the furnace stopped, there is no need of the bank up a fire. When the fuel on the grate exhausted, drum induced draft fan may stop running.
