natural gas fire tube boiler, ZOZEN knock-out product WNS series natural gas boilers have good performance

In the fire tube boiler, the flue gas produced by fuel combustion passes through the fire tubes or smoke tubes to heat the water, steam or water and steam mixture outside the fire tubes or smoke tubes. According to the flue gas passes, there is two-pass or three-pass fire tube boiler. Then, what is the natural gas fire tube boiler? The natural gas fire tube boiler refers to the fire tube boiler which burns the natural gas.

2.ZOZEN natural gas fire tube boiler working principle

ZOZEN WNS series natural gas fire tube boiler is a kind of horizontal internal combustion wetback boiler. The combustor burns the fuel to form the flame filling the corrugated furnace and transferring the radiant heat, this is the first pass. The high-temperature flue gas generated by the combustion gathers in the reversal chamber and turns to the second pass where is filled with threaded smoke tubes. After convective heat exchange, the flue gas gradually cools down and turns to the front smoke chamber, then the flue gas leaves the front smoke chamber and turns to the third pass that is light tubes area, then the flue gas passes the back smoke chamber and enters the economizer and condenser, and finally is exhausted into the atmosphere via the chimney. This is the working principle of ZOZEN natural gas fire tube boiler.

3.ZOZEN natural gas fire tube boiler advantages

1) The natural gas fire tube boiler has simple structure, compact size, easy installation, low production and construction costs.

2) The natural gas fire tube boiler has low failure rate, convenient maintenance, low maintenance and operating costs.

3) The natural gas fire tube boiler adopts the threaded smoke tube with high heat transfer efficiency which is independently developed by ZOZEN Boiler, which can extend the staying time of flue gas in the furnace to improve the thermal efficiency.

4) The natural gas fire tube boiler adopts the large-diameter corrugated furnace with sufficient steam storage and heating surface, which can reduce the thermal resistance to ensure that the boiler can produce the high thermal power and high-quality steam with a high efficiency.
