1.The body is a pot shell type full wet back downstream three return pyrotechnics tube structure, the flame in the large combustion chamber micro positive pressure combustion, combustion is full, the furnace heat load is low, harmful substances SOX,NOx emissions are small.
2.Corrugated furnace and threaded smoke tube structure, not only improve the strength and enhance the heat transfer effect, but also meet the needs of thermal expansion of each part.
3.Large boiler water volume and steam space, large range of load regulation. Reasonable design of the pot device, to ensure high quality steam quality.
4.Adopt new heat insulation material, light weight, less heat loss, good heat preservation performance.
5.The water level alarm adopts stainless steel as electrode rod and ptfe as insulation material. Insert from the top, not easy to stain, reliable performance, long service life.
6.The front and rear smoke boxes are connected by hyun chain, which can be opened easily and maintenance is convenient and quick.
7.Oxygen content adjustment (optional) system: the system can monitor the successful extension of the oxygen content, and the real-time data transmission to the control system, intelligent analysis by computer, automatically adjust the ratio of combustion equipment, make it always in the best working state, combustion efficiency greatly improved, which can greatly decrease the fuel consumption.
