China Horizontal Firetube Oil Gas Fired Steam Boiler for building material industry
Horizontal Firetube Oil (Gas) Fired Steam Boiler for building material industry
WNS series horizontal internal combustion full wet back oil and gas fired steam boiler, the flue gas flow can be divided into two forms of two return journey and three return journey.After the fuel is burned by the burner, the torch is filled in the full corrugated furnace chamber and transmits radiant heat through the furnace chamber wall, which is the first return journey.Of high temperature flue gas in the indoor together, to go to a second return, that is threaded pipe bundle area, the convective heat transfer, after the flue gas temperature is gradually reduced to smoke box, before the return of boiler flue gas used to smoke into the Settings in the top box out of the boiler economizer and condenser, three return boiler flue gas smoke box to enter the third return once upon a time, the light tube bundle area, then the smoke box after entering the economizer, finally into the chimney, the atmosphere.
Boiler Features:
1. The design, production, supervision and inspection of boilers are strictly in accordance with the Safety Supervision Regulations for Steam Boilers, JB/T 10094-2002 General Technical Conditions for Industrial Boilers, and JB/T 1619-2002 Technical Conditions for Boiler Body Manufacturing, so as to ensure long-term safety and stability of boilers.
2, the body for the pot shell type full wet back downstream three return firework tube structure, the flame in the large combustion chamber micro positive pressure combustion, complete extension, low burning heat load, less NOx emission of harmful substances.
3, corrugated furnace and threaded pipe structure, that is, to improve the strength, but also to meet the needs of the heat expansion of each part.
4. Butt joint is adopted in the welding of the main welding seam, and non-destructive inspection is conducted by X-ray and ultrasonic to ensure that the welding quality meets the national requirements.
5, the boiler water volume and gas space is large, strong capacity to adapt to the load.Reasonable design of boiler installation, to ensure that the steam water rate is less than 4%, to meet the higher requirements of users on the quality of steam.
6, the use of new heat insulation material, light weight, less heat loss, good insulation performance.
7. The water level alarm adopts stainless steel as electrode rod and teflon as insulation material.Inserted from the top, not easy to hang dirt, reliable performance, long service life.
8. The front and rear smoke boxes are connected by hinges, which can be easily opened, convenient for maintenance and maintenance.
This series boiler is three return fire tube steam boiler.It equipped with good performance burner and advanced techniques.The burning control,water feed,programs run,etc,is full automatic.This fantasy boiler is safe and reliable,and also has the advantage of compact structure,simple operation,easy installation,high efficiency,less pollution and noise,etc.

Production process
Production Line Quality Control:
1.Strict quality control system,From the material, welding, to
finished boiler shipment, from project , establishment, drawing
design, to final audit;
2. 100%NDT(non-destructive inspection) report of steel plate, tube
and welding rod;
3. 100%X-ray inspection report (welding seam): to ensure the
quality of the entire generator;
4. Hydraulic test report: ensure the standard working pressure and
safety.
