industry horizontal style natural coal steam boiler
Works industry horizontal style natural coal steam boiler because the steam boilers and conventional boilers are not the same, because it does not require annual inspection, so there are a lot of users recently asked my principles steam boiler, steam boiler is how it works, I will give you an analysis by the steam today working principles of steam boilers in steam systems, water heating in the heater to a predetermined temperature, the water supply pipe into the economizer, after further heating into the drum, along with the mixing pot of water down to the downcomer inlet waterwall header. Radiative heat absorbing soda water formed by the mixture in the riser in the drum reaches the waterwall tubes, the water from the steam separator means, steam separation. The separated saturated steam flows to the steam drum by the upper superheater, continues to be endothermic superheated steam of 450 deg.] C, and then sent to the turbine. In terms of combustion and flue gas system, the air blower into the air preheater is heated to a certain temperature. It is ground to certain fineness in the mill coal, a portion of the hot air from the air preheater carried into the furnace through a burner. Discharging pulverized coal burner and combustion air mixture is mixed with the rest of the hot air in the furnace and release large amount of heat. The hot flue gas flowing through the furnace sequence after combustion, Slag bundle, the superheater, economizer and air preheater, and then through the dust removal device, wherein the fly ash is removed, and finally sent to the chimney by the induced draft fan to the atmosphere. That's all steam boiler works with you about today, the company's steam boiler 0.5 tons 0.5 tons horizontal and vertical steam boiler fuel gas-free acceptance, there is a need to contact us.
Dezhou City, Shandong Province issued - an important part of "Dezhou 2018 2020 coal consumption reduction alternative work" (the "Program"), the Yajian coal consumption as an ecological civilization construction and environmental protection work, and resolutely fight pollution prevention tough fight. "Plan" put forward, as of 2020, total coal consumption Dezhou control in less than 18.5 million tons, clean heating rate of 70%.
According to "program" requirements, Dezhou vigorously for shutting down the environmental, energy, security and other 300,000 kilowatts of coal-fired units of non-compliance, especially running at least 20 years of pure condensing units and over 25 years of condensate pumping thermoelectric unit. At the same time shutting down out of small coal-fired boilers to reduce coal pollution. Upon completion of the city's 10 steam tons / hour and coal-fired boilers are all clear on the key areas in national, provincial and determined basically eliminated 35 tons of steam / h coal-fired boilers, 65 tons of steam / hour or more coal-fired boilers completed energy efficiency and ultra-low emissions transformation.
Dezhou will also expand the scope of central heating, promoting clean urban and heating, 2020, the Center City District (Germany City, Texas Economic Development Zone, the Canal Economic Development Zone) central heating area of 45 million square meters, the other 10 counties (cities, districts) central heating area of 41 million square meters, the implementation of central heating pilot projects in rural areas where conditions permit. For areas not covered by central heating, according to the resources in the area of heating conditions, combined with infrastructure construction, promote the substitution of gas for coal to other electricity-generation clean energy alternatives such as coal and biomass. As of 2020, Dezhou city's average clean heating rate of 70%. Among them, the city basically clean heating comprehensive coverage, average clean heating in rural areas reached about 55%.
In addition, Dezhou will continue to increase the proportion of natural gas consumption, substitution of coal consumption, encourage the development of direct supply of natural gas to large users to promote key industrial enterprises, industrial parks to achieve direct supply of natural gas. By 2020, increase the proportion of natural gas consumption in energy consumption to about 7%.
Hot water boiler and a traditional old-fashioned coal-fired boiler is how to deal with water shortages? Machine in use for some time there will be this or that problem, a serious delay the progress of work, causing great inconvenience to the people, such as water shortages, the question arises, hot water boilers and water shortage in the traditional old-fashioned coal-fired boilers It is how to deal with? Electric industry horizontal style natural coal steam boiler how to deal with water shortages: water level proofread each water level indicated by the right to judge whether the electric steam boiler water. In the electric boiler can not be determined when full of water or water vapor, can turn on the water faucet open water level, water flows out of the pot if not, indicating that water scarcity is an accident, otherwise it is full of water accidents. For the embodiment allows a small electric steam boiler waters operation, water may be called first, determines the electric steam boiler is mild or severe water shortage. This only applies to the water level gauge water hole communicating tube heating surface is higher than the highest water capacity and fire community large electric steam boiler. Otherwise it can not be called electric steam boiler water, because it will delay the time of the incident electric steam boiler water treatment, the worsening of the situation. When a slight electric steam boiler water, should reduce the fuel and air, the combustion decreased, and electric steam boiler feed water slowly to the normal level. Typically by adjusting a valve opening degree and the size, to control water flow rate and water, being careful not excess water. To quickly identify the cause of water shortage in the water and remove the process, and then check the electric steam boilers there is no unusual circumstances, after confirmation by the normal operation can resume electric steam boilers. When electric steam boilers severe water shortages, the need for emergency fire fighting shutdown. The fire shutdown procedures according to the method of implementation of the emergency shutdown, is strictly prohibited water to the pot and when serious water shortages. Some fireman personnel after the discovery of electric steam boiler water shortages, interrupted several times with water, each time a small amount of water replenishment way to cover up the accident electric steam boilers. This practice is very dangerous. If electric steam boilers are also less severe water shortage will cause biomass boiler leaks. If electric steam boiler water can cause serious electric steam boiler explosion. Only natural ventilation and cooling in electric steam boiler pot temperature dropped to below 70 ℃, water only slowly. Electric steam boiler for the water to normal level after thorough examination, no abnormal situation in order to re-start ignition, electric steam boilers to resume operation. Traditional old-fashioned coal-fired boiler using coal, gas, fuel oil and other fuel, these fuels are non-reusable primary energy, the future price will be higher. And the shortcomings of the traditional old-fashioned coal-fired heating methods are also caused by incomplete combustion, incomplete combustion can cause a lot of heat from the flue gas discharge out together, so it will cause energy losses. Boiler not only save electricity, but also saves time and effort, not the traditional coal-fired boiler heating boiler released by carbon dioxide, toxic gases, dust and other harmful substances, so users do not need to clean up, so it can save a large sum of maintenance cost.
Food factory industry horizontal style natural coal steam boiler should be noted that the ignition of the details need to pay attention when the details of the food factory steam boiler steam boiler ignition 1. food plant should be checked (including related accessories, Management) in front of a fire, and water supply. Before entering the water, the drain valve must be closed. Open air valve can discharge the boiler. 2, the treated water is slowly injected into the furnace, the inlet temperature is generally not higher than the boiler 40. When the water level rises to the minimum level of the water table, the water supply valve is closed, the stabilized boiler water level, the water level drops. With particular emphasis before the fire, you should check carefully the coal port and checkpoints in order to improve compliance with strict sealing conditions. Otherwise, it should clear the debris-side sealing surface, and a good gasket insertion, to ensure that meet strict sealing purposes. Since this is a forced air burner, during operation, gas leakage is not allowed, in order to avoid accidents. 3. When food factory fire steam boilers, open the bottom stoker grate and placed on the wood. After all the checkpoints closed, ignite the lighter. After strong fuel combustion, coal began to increase. When coal burning strong, continue to increase coal, closed after a stoker, hermetically sealed, turn the blower, so that coal continues to burn. burn. Strengthen the observation of the fire, the combustion gradually to normal.
