Condensing gas fired 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 combustion chamber of the series steam boiler is completely immersed in water, with good cooling conditions and long service life, and the back tube plate is not scoured by high temperature flue gas. 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. The front and rear smoke boxes are hinged for easy opening and maintenance.

This series of boiler products large steam space to steam out of the water speed is low, and built-in soda water separation device to ensure stable steam output. The steam boiler adopts threaded smoke pipe to enhance the heat exchange effect and improve the thermal efficiency. WNS series boiler adopts digital control technology, which can remotely control the combustion process. Boiler automation degree is high, all kinds of protection is perfect, to achieve automatic control of water level and pressure. The condensation heat exchanger made of special material can be added to the smoke outlet to reduce the smoke exhaust temperature and collect the sensible heat and latent heat in the flue gas, and improve the efficiency of the boiler (up to 95). 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 steam boiler fuel is ejected from the burner and ignited by high pressure electron ignition. After burning, the high temperature flue gas from the rear smoke chamber turns 180° and enters the second return. From the front smoke box turn 180° into the energy saver and condenser from the chimney into the atmosphere. Condensing gas fired boiler front smoke box adopts integral double door setting, smoke box door double seal. The form of integrity is good, beautiful, generous, maintenance when the opening is also very portable. The height of the chimney shall be 8 meters before delivery. The user shall determine the actual height according to the requirements of the environmental impact report approved by the local environmental protection department, but it shall not be less than 8 meters.

Condensing fired boiler can recover the latent heat of condensation of steam in the exhaust, but also reduce the harmful gas in the flue gas. The exhaust temperature of traditional oil and gas boiler is generally 160~ 250℃. It is impossible to condense into liquid water and release latent heat of vaporization, resulting in much heat loss. Gas fired boiler using condensation recovery device, reduce the exhaust temperature to 50~70℃. The sensible heat of flue gas and condensation latent heat of water vapor are fully recovered. The thermal efficiency of WNS gas steam boiler can reach more than 95%.

Gas fired steam boiler has rich economic benefits, improve the thermal efficiency of steam boiler. In the same time, the fuel can be greatly saved, thus greatly reducing the operating cost. Take 1 ton oil-gas steam boiler wan as an example, the natural gas consumption of ordinary boiler is 75.9nm3 / N (low calorific value of natural gas is 8500kcalNm3). Condensing boiler gas consumption is 66Nm3/h, if the boiler runs 24 hours a day. The condensing boiler can save 237.6Nm3 of natural gas per day, and 689.04 yuan of operating cost per day is saved based on the natural gas price of 2.9 yuan Nm3. The annual operating cost savings are $248,000 (based on 360 days of working time), even more than the cost of the boiler.

Condensing heat exchanger made of special material can be added to the smoke outlet of condensing gas fired boiler. Reduce the exhaust temperature to absorb the sensible heat and latent heat in the flue gas, improve the boiler efficiency (up to 95%). The flue has no bypass flue, which can be adjusted according to the size of the boiler load to adjust the use of the condenser. The boiler high temperature flue gas condensation treatment, and then recover part of the heat energy in the flue gas, after the recovery of the boiler exhaust temperature is about 80℃, flue gas temperature effectively reduced about 15%, boiler overall thermal efficiency increased about 8%. WNS type condensing gas boiler can effectively reduce the discharge of harmful gases and reduce the pollution to the environment in the process of heat condensing recovery of flue gas.
