Condensing gas boiler is a kind of automatic, horizontal internal combustion, low nitrogen condensation in one of the quick loading oil (gas) boiler. Condensing gas steam boiler body adopts wet back structure, the use of high efficiency and energy saving. Waveform furnace and back combustion chamber are the first return, and threaded smoke pipe is the second return. The energy saver and condenser are placed on the top of the boiler to form the third return of flue gas outside the furnace. This series of boiler energy saver, condenser heat exchange area is large, the water vapor condensation rate in flue gas is high, can fully absorb the heat released by the water vapor condensation in flue gas, thermal efficiency can be up to 99% or more.

In the exhaust heat loss of condensing steam boiler, in addition to the sensible heat of flue gas, water vapor also takes away a lot of latent heat of vaporization. If the steam in the flue gas is completely or partially condensed by reducing the exhaust temperature, and the latent heat released in the condensation process is recycled, the effective heat utilization of the boiler will be increased, and the thermal efficiency of the boiler will be significantly improved. The spiral fin tube and shell of the energy saver and condenser are made of ND steel with sulfuric acid corrosion resistance, which greatly improves the service life of the equipment. The combination of intelligent combustion control and automatic safety interlocking protection system ensures economic, environmental and safe operation.

This series of gas-fired boiler is aimed at the key technical factors such as the relationship between water vapor condensation rate and exhaust temperature, the relationship between condensation rate and thermal efficiency, and the corrosion rate of condensed water to different steel. Through the reasonable design of heating surface, reduce the exhaust temperature, to ensure that the steam in the flue gas to meet the design requirements of the condensation rate, so that the boiler thermal efficiency greatly increased. Due to the use of large size furnace structure and flue gas recirculation technology. Condensing gas steam boiler can fully achieve ultra-low nitrogen emissions, NOx emissions ≤30mg/Nm3.

Condensing steam boiler normal pressure operation, combustion, over temperature, water shortage and other multiple interlock protection. Fully automatic control, double open door, very convenient repair and maintenance. Working principle of the boiler is through a certain device will be the hot flue gas after the boiler combustion emissions (generally at about 140 ℃) heat from the recycle, after recycling the exhaust temperature of 60 ℃ or so, thermal efficiency is increased about 10%, so naturally to save about 10% of the gas, in the process of energy recovery, at the same time also can reduce the emissions of harmful gas, reduce the pollution of the environment.

Condensing gas steam boiler using flue gas rotary combustion technology, fuel is fully burned, harmful gas emissions to meet the relevant standards. This series of steam boiler energy saving device, condenser three-dimensional design, using high efficiency heat transfer, corrosion resistant materials, exhaust temperature can reach 60%-90%. High quality aluminum silicate insulation material and double sealing structure, good heat preservation and sealing performance.
