The gas-fired condensing steam boiler is a shell type three pass wet back oil (gas) boiler designed by our company according to the previous technology and experience at home and abroad.The operation of oil fired and gas-fired condensing steam boiler is automatic. The furnace adopts a corrugated furnace liner, which transfers radiant heat through the furnace liner wall. This is a return.The high-temperature flue gas generated by combustion converges in the return combustion chamber and turns into the secondary path, namely the spiral tube bundle area. After convection heat exchange, the flue gas temperature gradually decreases to the front smoke box, where it turns into the tertiary path, namely the light tube bundle area, and then the smoke box flows into the chimney and is discharged into the atmosphere.This series of products have the characteristics of safety, reliability, high efficiency, convenient maintenance, durability, automatic intelligent control, etc;All of them have been tested by the energy efficiency test center of the Special Inspection Institute, and all performance indicators are higher than the design requirements. The condensing boiler has reached the level at home and abroad.
The fuel gas steam boiler is a shell type full wet back downstream three pass pyrotechnic tube structure. The flame burns in a large combustion chamber under slight positive pressure and spreads. The combustion heat load is low and the nox emission of harmful substances is low.The corrugated furnace liner and threaded smoke tube structure of Yongxin boiler oil and steam boiler have improved the strength, and the gas-fired steam boiler has met the needs of thermal expansion of all parts.
Electric heating steam boiler, electric heating steam boiler is mainly composed of shell cylinder, shell head, electric heating tube installation tube, etc.The electric heating steam boiler has simple structure, convenient installation and use, and small floor area.Fully automatic operation, no noise in operation, no pollution to the environment.
Generally, the production of coke products is mainly based on high temperature retorting, and the retorting temperature usually needs to reach about 1000 ℃.After years of development, the technology and process of large-scale semicarbon heat transfer oil furnace are relatively mature, and the conditions for improving the unit output of equipment to achieve large-scale production have been met. In recent years, the output of each newly built semicarbon steam boiler can reach about 500000 tons/year, or even more than 1 million tons/year. For example, two recently put into production semicarbon boiler furnaces with 7.63 meters high carbonization chamber in the mining and coking plant,The output of each building can reach 1.1 million tons/year.However, the production of semicarbon is dominated by low-temperature retorting. The retorting temperature is generally about 600 ℃. Due to the late start, the annual output of a single furnace of the semicarbon low-temperature retorting furnace equipment is mostly around 30000 tons/year. The Forum low-temperature retorting furnace equipment with a scale of more than 50000 tons/year is still in the exploration and test stage, and the technology of large-scale equipment is still immature,Only one furnace with multiple doors and other combined technologies can be used to realize centralized mass production.
The horizontal biomass steam boiler body is designed and manufactured with three return, wet back, eccentric furnace and asymmetric structure.The furnace liner can be designed as a waveform to reduce the thermal expansion stress and increase the radiant heating surface.The use of heat transfer threaded smoke tubes has strengthened the heat transfer effect, achieved the characteristics of fast boiler temperature rise and pressure rise, and improved the thermal efficiency of horizontal steam boilers.At the same time, due to the disturbance of flue gas in the pipe, it is not easy to accumulate ash in the pipe, which plays a role of self-cleaning.Preferential price for steam boiler.
