Oil gas boilers have obvious characteristics. The main fuel is oil or gas. According to their functions, they can be divided into steam boilers and hot water boilers. Most of them are designed with large furnaces, with thermal efficiency of more than 98%. At the same time, they also have the characteristics of fully automatic and safe operation. Shanghai Horizontal fuel gas steam generator Generally speaking, oil and gas boilers adopt excellent boiler body design. WNS horizontal boiler adopts wet back three return structure, which can reduce the exhaust gas temperature and make the boiler thermal efficiency reach more than 90%. Therefore, the combustion efficiency is relatively high, greatly extending its service life. small-scale Horizontal fuel gas steam generator factory In addition, in the design of oil and gas boiler, there are often hinged front and rear smoke boxes. The maintenance method is simple. Most of them are insulated with light aluminum silicate fiber to reduce heat loss. The external use of all stainless steel plate skin improves the appearance quality. In addition, the oil and gas boiler is equipped with an excellent combustion machine, which greatly improves its stability. The combustion machine has an automatic purging function, It can also prevent deflagration during ignition.
To understand the advantages and disadvantages of hot blast stove and hot water stove, we should start from the working principles of the two boilers. The hot water boiler can increase the indoor temperature by burning hot water, circulating hot water, heat dissipation, etc. General purpose (radiators, floor heating pipes, water heating air conditioners are generally used for heating in families, enterprises and institutions). Shanghai Horizontal fuel gas steam generator The hot blast stove can increase the indoor temperature by heating the air. Generally, a hot channel wind belt is required. It is generally used for workshop, breeding, planting and special heating or drying. Most areas in northern China are cold, such as the three northeastern provinces, Inner Mongolia, Xinjiang and other cities. The colder temperature is more than minus 40 degrees Celsius. There are hot water boilers and steam boilers for heating. Its disadvantage is that it is afraid of circulatory system failure or power failure. small-scale Horizontal fuel gas steam generator factory Once the power failure exceeds two to three hours, if the insulation is not good, the pipeline will freeze. The heating of hot blast furnace is not frozen, and the temperature can be set. It can save 40% energy than hot water heating and 50% energy than steam boiler heating. This comparison is practical. The hot blast stove does not need to apply for a use certificate, the steam boiler and pressure hot water boiler need to apply for a use certificate, and the functional department also needs to carry out annual inspection every year, but also has to bear the cost.
Gas steam generator is also called gas steam boiler. The steam temperature is not high when the steam gas and steam generator has a fault. How can we solve this problem. Shanghai Horizontal fuel gas steam generator Generally, there are two situations: physical characteristics of water vapor: it will evaporate when reaching 100 ℃, and it is impossible for steam to reach a higher temperature. Although the measured temperature of steam is higher when it receives pressure, the temperature will drop to 100 ℃ as soon as it reaches normal atmospheric pressure. small-scale Horizontal fuel gas steam generator factory The way not to imagine that the pressure of the steam engine will rise is to make the steam negative pressure. Every increase of about 1kg in steam pressure will increase the steam temperature by about 10 ℃, so by analogy, you need to increase the pressure as much as you need the temperature. I hope it is useful to you.
The waste heat boiler greatly improves the utilization rate of heat released by fuel combustion, so this kind of boiler saves energy; Fuel oil, gas and coal combustion generate high-temperature flue gas to release heat. The high-temperature flue gas first enters the furnace, then enters the waste heat recovery device of the front smoke box, then enters the pyrotechnic tube, and then enters the waste heat recovery device in the flue of the rear smoke box. The high-temperature flue gas turns into low-temperature flue gas and is discharged into the atmosphere through the chimney. Shanghai Horizontal fuel gas steam generator Conditions conducive to quick startup of waste heat boiler: (1) The waste heat boiler adopts forced circulation, which has the priority of quick startup. (2) The flue gas baffle is hydraulically controlled, which can be used to adjust the sky in principle. The flue gas flow into the boiler is reduced. (3) The adjustable guide vane at the inlet of gas turbine can not only adjust the flue gas flow of gas turbine, but also increase or decrease the exhaust gas temperature of gas turbine through the selection of IGV temperature control mode. (4) The steam turbine bypass is designed for the rated evaporation capacity of the boiler. (5) The welded bends and headers of each heating module of the boiler are in the boiler. (6) Similar boilers in other gas turbine power plants can not be reduced when starting, and can be used to adjust the main steam pressure of the boiler. Outside the wall, contact with high-temperature smoke is avoided. small-scale Horizontal fuel gas steam generator factory Operating experience of gas turbine load, such as simultaneous startup of gas turbine and waste heat boiler (flue gas damper fully open). Under the possibility of quick startup of waste heat boiler, the water level of steam drum and deaerator will lose control after the flue gas baffle is opened.
Economical and energy-saving: the new generation of biomass pellet fuel can save 30% - 60% of the operating cost compared with oil, gas and electric heating boilers. Convenient installation: this series of generators do not need to be inspected, and the tedious annual approval procedure can be avoided. Shanghai Horizontal fuel gas steam generator At the same time, the machine is assembled for modules, and professional installation procedures are not required. High efficiency operation: adopt the design of multiple flue gas backflow, optimize oxygen enrichment for many times, cooperate with professional dust removal and energy saving equipment, the thermal efficiency reaches more than 90%, and can continuously produce steam. Low carbon and environmental protection: Through reasonable design, biomass fuel is semi gasified and burned, and smokeless combustion is achieved. Reliable security: It is equipped with pressure, water shortage, security valve and other protection devices to ensure stable operation and reliable security of the boiler. small-scale Horizontal fuel gas steam generator factory Simple operation: microcomputer intelligent one button operation, automatic feeding, automatic ignition, cycle start stop and fault alarm functions are used for simple operation. The labor intensity is greatly reduced, and the use of the boiler is more humanized. Convenient maintenance: the overall structure of the boiler is reasonable, and the installation is convenient. There is a cleaning port under each furnace. The main components have inspection ports for future maintenance and repair.
As a large equipment, the maintenance of gas-fired hot blast stove is one of the things that must be done. Shanghai Horizontal fuel gas steam generator Regular maintenance can not only keep the hot blast stove clean, but also improve the service life of the hot blast stove. Therefore, it is the top priority in the use of hot blast stove. Today's editor will tell you how to maintain the hot blast stove regularly. In many manufacturers that use hot blast stoves, in order to better develop the enterprise, it is necessary to increase the number of hot blast stoves and improve the performance of hot blast stoves. small-scale Horizontal fuel gas steam generator factory When enterprises purchase hot blast stove equipment, they must understand their own needs and the products of hot blast stove manufacturers in the market. Therefore, the small edition of gas-fired hot blast stove tells us the problems to be considered in the selection of hot blast stove.
