The gas condensing steam boiler is a mechatronics equipment, which is composed of the boiler body, burner, electric control cabinet, feed water pump, pipeline valve instrument and so on. The gas fired condensing boiler unit is equipped with the original imported burner, and the unit body adopts the mature structure of the horizontal internal combustion three-pass wet back type. The fuel (oil/gas) is sprayed out from the burner through pressure atomization at high speed, and burns in the furnace with slight positive pressure. The high-temperature flue gas after combustion is radiated and heat exchanged in the furnace and then turns into the second return smoke pipe to the front smoke The box, then turned 180° into the third return smoke pipe, and then discharged into the chimney through the rear smoke box and condenser into the atmosphere.

This series of steam boilers eliminates the traditional two- and three-pass “equal flow rate” design point of view in the arrangement of the convection heat exchange flue pipe area. The new idea of ​​”equal resistance” design is adopted to lay out the convection heat exchange surface, which breaks through the traditional design idea of ​​determining the diameter of the furnace by the size of the flame diameter in the furnace design. The gas-fired steam boiler adopts a large corrugated furnace structure, which greatly increases the radiant heat transfer area and reduces NOX emissions.

The condensing steam boiler uses threaded smoke tube technology in the convection heat exchange tube area, and the boiler efficiency reaches more than 96.2%, which greatly improves the boiler efficiency. The gas fired condensing boiler smoke box adopts a double-sealed small smoke chamber structure to prevent smoke leakage and facilitate user maintenance. This series of boiler heat preservation uses aluminum silicate fiber felt, which has a good heat preservation effect. As we have done a lot of work in combustion and heat transfer, we have adopted some new structures and new technologies to greatly reduce the volume of this product, reduce the area of ​​the machine room, and reduce the weight.

The combustion chamber of the WNS series steam boiler adopts a corrugated furnace, which has good thermal expansion performance. The gas fired condensing boiler combustion chamber is equipped with an explosion-proof door. The furnace body is equipped with high-sensitivity temperature, pressure and water level sensors. The controller constitutes a high-reliability and multiple safety protection. The control system ensures the safe operation of the boiler; the boiler has large water volume, stable and reliable operation, and high heating quality.

The condensing steam boiler adopts a large furnace and corrugated furnace structure, which increases the radiation heat transfer area and facilitates the full combustion of fuel. This series of gas fired boilers uses fuzzy control technology based on artificial neural networks and world-famous burners to realize automatic adjustment of combustion according to temperature, pressure and time, so that the boiler can operate efficiently and economically under different conditions and minimize The fuel consumption is reduced.
