energy saving water tube coal fired hot water boiler
Comparison on electric boilers and gas boilers analysis that is both: a wide range of aspects of the early vote gas than electric boilers cheap, how much detail should be distinguished from gas boiler brand size, with or without condensate recovery and technical maturity of all determine the price of gas boiler; brand electric boiler, the applicable type, excellent technology, quality products; create two related conditions, such as plumbing, gas station; select high and low voltage electricity, create distribution and so on. If you choose gas boiler, gas pipeline itself, it does not demand an opening fee (usually about opening expenses 100 000), if the price of natural gas at a relatively high number, it is uneconomical, though you used to buy a cheap gas boiler, but all the cost is still reasonably high, and the gas boiler full of danger, high demand for security measures. If you choose electric boiler (that is, the kind of electromagnetic boiler instead of electric heating), capital of electromagnetic boiler itself is relatively high, after all, is a product of modern, high-tech, itself is not high-tech gas-fired boiler. If a region of relatively cheap price, it is highly recommended to use electric boiler. Plus electric boiler is the new environmental protection equipment, all kinds of pollution does not occur is in line with the development trend of the times. Fully automated equipment, personnel do not need guards. Calorific value gas in a wide range of heating season / purity of non-compliance (even if the contract explicitly re-appointment), and the calorific value of more basic electrical 1: 7, the proportion of LNG to be higher, lower coal bed methane (calorific value is multiplied by the thermal efficiency of the device ). In this case, saving electricity than gas about 1/3, according to the grapevine, is expected this year, Liaoning low power dropped to less than 0.3 yuan (business), that electricity than gas savings will exceed the estimated half. Other regions such as Xinjiang, Inner Mongolia, are relatively low price, is very suitable for power boilers. It covers an area of respect, if the gas to create a gas station, then it must be a space-saving electric boiler and electric boiler is the basic module assembly, covers an area of very little, according to the actual situation; and gas boiler explosion venting port and must demand of security area. Natural gas boiler manufacturers comes from the power point of view, electricity is no waste, waste gas, waste water, renewable power, gas emissions is still there, petrochemical and power is not renewable, although countries in the generosity of view, the price decline in space more large, but also more conducive to the use, in particular, Valley electric. Ultimately, if it is 30 000 m2 of non-continuous heating conditions (such as schools, shopping mall, office, public venues, factory, warehouse, etc.), advocated choose electric thermal storage boilers, the best choice for 10kv high voltage device, you can save some investment, and the province as well as policy. But if the area is less than 10,000 m2, the election 0.4kv low-voltage equipment is also good. Equipment and electric boiler is automatic operation, do not need special duty, usually around six meters do not consider lifting frame height coefficient, the heating time can be self-control, these areas are relatively municipal district heating is also very advantage. So gas boiler and electric boiler has its own advantages, depending on the actual situation in each region to decide, but to distant viewpoint in terms of selecting the electric boiler is still relatively cost-effective. In recent years, due to air pollution, coal-fired boilers were fire. Gradually immersed in people's day sideways fuel gas energy saving water tube coal fired hot water boiler. But coal-fired hot water boiler fuel to bring our lunch together, but also brought us a little problem. That's hot water boiler should be how to maintain? Below small way to tell us hot water boiler maintenance: 1, according to the water quality around, once every six months cleaning operations, the eradication of hot water boiler scale, otherwise, simple convection tube fouling, resulting in convection duct obstruction and burn. 2, if found suction force reduction furnace, the furnace should be cleaning, the furnace door, or in the neck of the chimney with a rubber hose running water flushing. Scale furnace can be opened to eradicate the use of at least 1 year after the manhole survey scale thickness, plus cleaning detergents, can also be added 5-10kg caustic soda or hydrochloric acid 24-36h, add boiling furnace furnace cleaning wash. 3, the operation of the boiler water or hot water to stop the combustion of dry, to avoid the formation of disturbances, severe dry furnace if found, immediately interrupted heating boiler After cooling, to identify the reason, troubleshooting. Must not the temerity to add water, avoid cracking furnace hit. 4, when the winter shutdown, it is necessary to put the net water furnace, hot water boilers to avoid freezing. 5, when the summer without hot water boiler, furnace should put the net water, dry curing with lime. 6, hot water boiler operator skill necessary to operate, grasp the hot water boiler functions, procedures and processes, to eradicate illegal operation.
Small series to introduce horizontal steam boiler steam boiler arch horizontal tube plate with threaded pipe drum composition, high heat transfer efficiency, boost fast enough output, high overload capability, hard fouling smoke tube. Today, let us together look at it. Horizontal welding binding sites steam boiler using high-temperature region and large machining bundle special treatment to ensure the welding quality and service life. Flammable, widely used fuel, burn bituminous coal, anthracite coal, firewood, industrial waste, organic waste and so on. It solves the problem of tube plate crack, eliminating the dead zone at the bottom of the drum, good water cycle effect, prevent the lower drum drum kits. Horizontal steam boiler compact structure, small dimensions and saves capital investment, easy installation, tipping valves, and piping to run hydropower. Stable, easy adjustment, the unique design of air sealing, bank up a fire a long time. Times atmospheric pollutants are oxides of dust, sulfur and nitrogen contained in horizontal steam boiler flue gas, which can achieve emissions targets Protection index when a predetermined number of times to unpurified. These substances emissions control combustion pretreatment, improved combustion techniques, dust removal, desulfurization and denitration. By means of a high chimney stack can reduce the concentration of pollutants in the atmosphere of the area.
Inter-regional Pingdingshan Coal Industry Group Co., Ltd. by the Pingdingshan Shenma Group and two Chinese top 500 enterprises founded by restructuring, cross-industry, cross-ownership and transnational business of large state-owned energy and chemical group, under the People's Government of Henan Province , is the most complete variety of coking coal, thermal coal production base, has Asia's largest chemical production base in nylon. Carefully selected and comparison, fast boiler Pingmei cooperation with party has chosen to provide a 2 tons of steam electric steam boiler (WDR2.0-1.25-II) by a fast side.
About six tons of steam boiler shutdown of a temporary shutdown: It is planned, therefore slow cooling during shutdown protection device, it should also pay attention to safety, pause furnace according to the rules in Chapter IV Fenghuo (pressure fire) get on. 2, safety shutdown: care should be completely stopped even on normal operation plan for 1 to 3 months to be a shutdown, shutdown should maintain more safety injection apparatus, after the shutdown, and other water-cooled furnace to below 70 ℃ when they let go of the gas, open manholes, hand holes, rinse the pot with water scale. 3, emergency shutdown: the boiler operation, when the case of the following circumstances, should an emergency shutdown, and notify the relevant authorities. (1) expanding the cease-fire should first see if the water table level is called to take water law. If Inception water table, water cock side, and then close the steam cock, and then turn on the water faucet open and close repeatedly called after water, still can not see the water. (2) All water supply equipment failure. (3) All water gauge, pressure gauge, safety one of all the failures. (4) a boiler or furnace wall element damage, serious threat to the safe operation of the boiler, emergency shutdown, should focus on preventing the stop of the accident and the specific steps as follows: ① first blowing off; ② the coal on the grate red raking; ③ Close induced draft fan.
