Gas steam boiler is horizontal, internal combustion, three return shell structure, and oil, gas as fuel steam boiler series products. 8Tons steam boiler using programmable controller as a central control type of operation interface for users to choose. The main functions of the boiler control system include automatic water supply control, automatic combustion control, automatic oil temperature control (heavy oil and residual oil), high pressure (low pressure) protection (gas fuel), program control, automatic ignition, furnace shutdown and other safety protection, etc.

Gas fired steam boiler adopts wet-back three-return structure, symmetrical arrangement of smoke pipe, uniform distribution, can improve the stress distribution of tube plate. The wet-back combustors of this series gas fired boiler are completely immersed in water, with good cooling conditions and long service life. The application of corrugated furnace liner not only increases the heating surface but also relieves the damage caused by thermal expansion and contraction to the combustion chamber and improves the intensity. Large steam space makes the steam out of the water speed is low, and the built-in soda water separation device, to ensure stable steam output.

This series of steam boiler smoke outlet can add condensation heat exchanger made of special material, reduce the smoke exhaust temperature and collect the sensible heat and latent heat in the flue gas, improve the boiler efficiency (up to 98%). 8Tons steam boiler using threaded smoke pipe, enhance heat exchange effect, improve the thermal efficiency. The flue has a bypass flue, which can be adjusted according to the size of the boiler load to adjust whether to put into the use of the condenser. Gas fired boiler with good technical performance of the automatic burner as the main combustion equipment, the combustion program of the burner by the more advanced combustion program controller control, can achieve the normal combustion of the necessary various functions, can be in the normal state, accident state and under special circumstances, automatic implementation of protective furnace stop.

WNS series steam boiler combustion chamber adopts corrugated furnace, low position layout, effectively increase the heat exchange area, enhance the turbulent heat transfer of high temperature flue gas. At the same time, it can reduce the service life of equipment caused by thermal expansion and cold contraction. Boiler control adopts fully automatic operation, computer program control combustion automatic adjustment, steam boiler has automatic ignition flameout of water level, high and low water level steam overpressure automatic protection and other functions, to ensure the safe operation of boiler combustion. Gas fired steam boiler is widely used in schools, textile factory, clothing factory, printing and dyeing factory, restaurant, food factory, beverage factory, bean products factory, meat products factory, cannery, brewery, pharmaceutical factory, packaging factory, building materials factory, coating factory, swimming pool and other enterprises and institutions.

8Tons steam boiler front smoke box with hinge connection, double seal and easy to open. Adopt light quality sealing heat insulation material, smoke insulation, reduce the temperature of front and rear panels and improve the thermal efficiency. The inlet of the boiler water supply is provided with a mixing device. The low temperature water supply first scour the smoke tube bundle, and then contact the furnace and fire box and other high temperature parts after the temperature of the water supply is raised, which effectively avoids the occurrence of local subcooling boiling phenomenon and ensures the safety performance of the boiler. WNS series boiler adopts intelligent energy-saving control system to control the boiler and steam supply (water supply) system, and adjust the fuel supply according to different loads to save energy.
