The waste heat boiler for hazardous waste incineration is an important part of the hazardous waste rotary kiln incineration system. The heat source is the high-temperature waste gas containing strongly coking and cohesive ash after hazardous waste incineration. Hunan Horizontal gas steam generator Generally, this type of waste heat boiler adopts single flue or multi flue layout, and convection heating surface is arranged in the flue. During operation, strongly coking cohesive ash is easy to adhere to the convection heating surface, leading to flue blockage, affecting the safe and normal operation of the waste heat boiler. According to the characteristics of hazardous waste rotary kiln incineration system, a kind of waste heat boiler with special structure suitable for the system was developed, which successfully solved the problems of ash deposition, wear, air leakage, corrosion, etc. vertical Horizontal gas steam generator manufactor The water circulation mode of the waste heat boiler is natural circulation. The working medium directly enters the drum, then is led out from the drum, flows into each membrane water wall through the downcomer, is heated here, then led back to the drum through the steam conduit, and is separated by the steam water separator, and then led out of the drum saturated steam with rated parameters.

Inspection and use preparation of oil and gas boiler. Inspection of the furnace and flue, and the soot and sundries in the furnace and flue shall be removed. Hunan Horizontal gas steam generator Check the boiler accessories to see if they are in good condition; Whether the cock can rotate easily; Whether the instruments and control devices are in good condition and clean. After inspection, the pressure gauge cock shall be in working condition. Check the automatic control system. Check the auxiliary equipment of oil and gas boiler. Check the combustion equipment to see if the combustion equipment is in good condition; For mechanical transmission system, coal handling system and ballast system, the test steering is normal; The spring of the gearbox shall be properly compressed and lubricated; The indication of coal door gauge is correct. vertical Horizontal gas steam generator manufactor The eagle iron is neat and complete, and the ballast plate is complete. Check the heating surface and ensure that the equipment coupling is firmly connected; V-belt is loose properly; The lubricating oil is in good condition; The cooling water is smooth. After passing the test, install the protective cover, test run separately, and pay attention to the current during idling.

When the boiler is shut down, the temperature of the heat transfer oil can be reduced to below 70 ℃ before the shutdown of the hot oil pump. In case of sudden power failure, extinguish the fire immediately, and then implement the operating procedures. Otherwise, the furnace tube will be burned out and the loss will be large. According to the type of heat transfer oil boiler, heat transfer oil shall be reasonably selected to prevent overheating. Hunan Horizontal gas steam generator When purchasing unqualified heat transfer oil, do not save money or mix heat transfer oil indiscriminately. Otherwise, the consequences will be very serious. Prevent the oxidation of heat transfer oil. The strict heat transfer oil is more than 50 degrees in contact with the air, which will make the heat transfer oil crack. Its speed is amazing, and the consequences are relatively serious. After normal operation, the test crew needs to close the exhaust valve on the auxiliary exhaust pipe. After 6 months of use, the heat transfer oil must be sampled and tested according to the instructions. If problems are found, the heat transfer oil must be replaced immediately. vertical Horizontal gas steam generator manufactor However, it should be noted that different types of heat transfer oil should not be mixed. The circulation speed of the heat transfer oil should not be less than 1.5m/s. Due to the excessive temperature difference between some entrances and exits, the original design requirements were destroyed, the heat transfer oil could not maintain the original circulation state, the boundary layer became thicker, and the thermal resistance became larger, making the furnace wall exceed the oil film temperature, leading to carbon deposition, cracking, polymerization, coking, and even burning through the furnace tube.

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. Hunan Horizontal gas 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. vertical Horizontal gas steam generator manufactor 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.
