Fire Tube Boiler for Sale

Fire tube boiler is the flue gas generated after the combustion of fuel flows through the fire tube or smoke tube to heat the water, steam or steam-water mixture outside the fire tube or smoke tube. Fire tube boiler is also called shell boiler. Due to the limitation of its structural conditions and characteristics, fire tube boilers have low efficiency and are generally used by users with small capacity.

1. Different nature: Water tube boiler is an industrial boiler with a combustion chamber and a heating surface arranged outside the drum, causing water and steam to flow in the tube. Fire tube boiler is the flue gas generated after the combustion of fuel flows in the fire tube or smoke tube, heating the water, steam or steam-water mixture outside the fire tube or smoke tube.

2. Different characteristics: Due to the limitation of its structural conditions, fire tube boilers have low efficiency, and are generally used by users with small capacity. Since the cross section of the inner tube of the water tube boiler is smaller than that of the outer tube, the flow rate of the steam water is greatly increased, and the steam generated on the heated surface is immediately washed away, which improves the water absorption rate of the boiler.

3. Different structure: The overall structure of the water tube boiler includes two parts: the boiler body and auxiliary equipment. The basic structure of the fire tube boiler is to install small cylinders, tubes or other shaped shells in the large cylinder (pot shell).

WNS Series Gas Oil Fired Industrial Steam Boiler

The most optimized threaded smoke pipe is used to ensure the output, efficiency and performance during operation. During normal operation of the boiler, there is no dust accumulation in the threaded smoke pipe. The outlet flue gas window is provided with a coarse dust separation steering chamber to achieve the purpose of removing dust in the boiler and to ensure that the boiler smoke emissions meet the national environmental regulations. The use of arched tube sheets reduces thermal stress, advanced technology and technology to eliminate the possibility of tube sheet cracks. Install a baffle at the front tube plate to direct the return water flow to the front tube plate, improve the water circulation here, and make the front tube plate fully cooled; there are risers on the left and right of the boiler. It produces supercoiled boiling, and the sludge is not easy to deposit, and there is no drum bulge. The boiler has a compact structure, the smallest size of the boiler, and light weight, saving the construction cost of the boiler room.
