economical 1-20ton coal fired hot water boiler for hotel
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 economical 1-20ton coal fired hot water boiler for hotel. 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.
Boilers factors leading to incomplete combustion of boiler fuel used in modern industry, not only solved the problem of conventional boilers produced by environmental pollution, but also reduce the use of coal and other resources. But its combustion products, we sometimes found to contain a large amount of combustible material, and black ash, and combustion gas contains a lot of carbon monoxide combustible components. Such a phenomenon is a typical problem of incomplete combustion. Then the factors causing incomplete combustion of boiler fuel, what does? (1) a boiler furnace temperature enough below 600 ℃, good combustion can not be established in general structure. The amount of air (2) supplied in the fuel can not meet the need for complete combustion of the combustible component. The amount of air (3) of the boiler supplied sufficiently due to mixing a bad contact, the combustion disorder. (4) abnormal accident. (5) the fuel as received too much water, the moisture of more than 45% of the fuel is difficult to ensure the normal combustion boiler. (6) the fuel particles are too large, is not conducive to the combustion reaction. (7) The reaction time is insufficient combustion, boiler grate vibration amplitude is too large, the interval is too short, short burning time. (8) much ash, ash coke particles wrapping, slow combustion, (9) a feed lot, on the grate boiler fabric layer is too thick, not gas-solid benign mixed. (10) the feed grate or thin material less heat storage capacity is not strong. Incomplete combustion of fuel, not only a waste of fuel, while the impact performance of the boiler also to some extent, so we must note that when using these factors mentioned above.
Shandong Zhaoyuan Mining Group Co., Ltd. is a large state-owned local asset management companies, gold mining dressing and smelting for leading industries, operates in the area of tourism, services, precious metals, real estate, eco-agriculture, with total assets of 10.2 billion yuan, Shanghai gold Exchange is an international provider of standard gold bullion. July 2017, Shandong Mining Group and fast boiler steam signed a 0.5-ton electric heating steam boiler which mainly produce steam for metallurgical mineral processing and other manufacturing processes, energy defeating small, strong ability to supply steam .
The reason gas steam boiler flame of abnormal phenomena and processing method. Flameout for the following reasons: 1. Auxiliary trip or power interruption. 2. boiler combustion instability. 3. When the load is too low, due to the sudden drop in load, ignition energy mill will be lost or the combustion is automatically stopped. 4. mutation coal, low volatile or low calorific value. Fuel gas boiler is not only fuel but also refers to the gas boiler. Previously no such dual-fuel boiler, burner because either fuel or gas, no dual fuel burners. With the rapid development of the world energy equipment, some European countries begin production and sales of fuel gas burner, dual fuel burner and boiler combination of organic birth of a new breed of boiler - fuel gas-fired boiler. 5, the automatic combustion flame detectors or failure resulting in failure to trip mill. 6. The furnace wall or squib serious improper boiler soot-blowing operation, a large amount of steam into the combustion chamber. 7, coal pulverizing system, fuel system failure, resulting in a substantial amount of fuel reduction or interruption. A large amount of water or impurities in the fuel oil gun clogging, or atomized vapor pressure is too low. Second, the phenomenon: 1, furnace pressure was significantly higher, flameless furnace flame monitoring CRT display. Pit of fire no fire. BTG MFT alarm window alarm indicator lights. 2. The unit load is reduced, steam flow drops rapidly, and the temperature of each section of the working medium vapor pressure decrease, a sharp increase in oxygen index. 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. 3. Treatment: 1. If you refuse to run MFT protection, emergency stop should be handled according to the situation and stop the supply of fuel. 2.2. Identify the cause of stalling, and try to eliminate it. Conduct a comprehensive inspection of the boiler, and to confirm proper before the device is restarted.
