The waste heat recovery of flue gas can not only be used for heating or power generation to achieve energy-saving effect, but also can be beneficial to environmental protection and achieve dual effects of energy conservation and environmental protection. Shenyang Automatic electric steam generator In general, the important equipment of waste heat power generation is waste heat boiler, which mainly uses heat or combustible substances in waste gas, waste liquid and other working medium as heat source, and produces steam mainly for power generation. There are many ways to recover waste heat from flue gas of waste heat boiler. Generally, comprehensive utilization of waste heat is followed by direct utilization and indirect utilization. small-scale Automatic electric steam generator factory Generally speaking, if heat sources are needed in the process, the waste heat utilization is mainly comprehensive utilization. First, the heat source is recovered and fed back to the process for reuse. If there is any surplus, it can be used for power generation or as the heat source for central heating; If there is no surplus, it will be directly used instead of being used for power generation; If the process does not need more heat sources, then indirect use, mainly power generation or public heating.

It can only be prevented by adding medicine to the pot. Shenyang Automatic electric steam generator Adding drugs to the boiler can further soften the water quality, making up that the softening water equipment cannot replace silicon, sulfur and heavy metal ions and anions, so that impurities such as suspended solids, water slag and scale in dissolved water have good looseness and fluidity, and then the impurities are discharged by sewage, thus preventing scale. The water treatment method is carried out in the pot, so it is called water treatment method in the pot. small-scale Automatic electric steam generator factory Therefore, boiler water treatment actually includes water treatment of feed water and quantitative feeding treatment in the boiler. Water treatment should only be carried out without adding drugs. The boiler water index basically does not meet the specified requirements, and the boiler cannot operate under good water quality. This is also the main reason for the softened water device. The softened water is also qualified, and the boiler will also be polluted.

The air storage tank in the air source system shall be installed behind the rear cooler, so as to prevent oil vapor and liquid water from gathering in the tank and reduce potential safety hazards as far as possible; The lower temperature of other air stored in the tank can also reduce the volume of the body. Shenyang Automatic electric steam generator When connected with screw compressor and other air supply equipment, the air receiver can be installed behind the dryer. At this moment, the air entering the air receiver is dry and there is no condensate in the tank. The air tank is a pressure vessel, and each air tank shall be equipped with safety valve, pressure gauge and other necessary safety supervision equipment. small-scale Automatic electric steam generator factory The application and maintenance shall strictly comply with the relevant provisions of pressure vessels; The air tank shall be equipped with a manhole or hand hole for maintenance, and the lower part of the tank shall be equipped with a drain valve, which shall be regularly drained; The air storage tank is usually installed outdoors, so it should be protected from direct sunlight and there should be no high temperature heat source nearby.

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. Shenyang Automatic electric 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 Automatic electric 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.

The boiler adopts the combustion equipment suitable for the combustion of biomass fuel - reciprocating grate. In the structural design of the boiler, the furnace space of the boiler is larger than that of the traditional boiler, and the reasonable arrangement of the secondary air is conducive to the full combustion of a large amount of volatile matter released instantaneously during the combustion of biomass fuel. The boiler can be equipped with oil (gas) ignition burner to realize ignition automation. Shenyang Automatic electric steam generator The feeding, combustion, slag removal, water supply and ignition of the boiler can be automatically controlled, and the operation is convenient. The boiler is equipped with an automatic ash cleaning device, which can remove the ash on the heating surface of the boiler in time to ensure the efficient and stable operation of the boiler. The tail of the boiler is equipped with an economizer, or an air preheater according to the user's needs. Compared with the traditional boiler, the boiler has higher efficiency and lower exhaust gas temperature. High efficiency thermal insulation materials are used, the boiler surface temperature is low, and the heat dissipation loss can be ignored. small-scale Automatic electric steam generator factory All pressure parts are made of excellent boiler steel in strict accordance with Chinese national codes and standards. Each boiler shall be strictly inspected and tested before leaving the factory, including hydrostatic test and X-ray inspection. Manholes, inspection doors, fire observation holes, etc. are set to facilitate maintenance. The major characteristics of biomass boiler are: energy conservation, environmental protection, and easy installation and use.
