Description
Technical field
This utility model relates to gas fired-boiler field, is specifically related to a kind of efficiently double-condensing gas module stove.
Background technology
Condensed type combustion gas module furnace is a kind of novel central heating appliance, and its effects of energy conservation and environmental protection is notable, is widely used in large-scale occasion central heating, the supplying hot waters such as Factory Building, office block, Shang Zhu community, hospital, supermarket, hotel, bath center, swimming pool.
Being provided with several gas modules in the body of heater of gas module, gas module is connected with the outlet flue above body of heater by smoke collection pipe.Mainly use natural gas or coal gas as fuel due to gas module.Burning formula (example is in natural gas CH4+2O2=CO2+2H2O) and the ratio of air oxygen according to fuel are learnt: during gas module work, the air supply needing more than 10 times is just provided that the oxygen needed for full combustion of fuel, and air supply is from the periphery of burner assembly and bottom.
Period, during fuel combustion, producing high temperature heat in the combustor of gas module, this high temperature heat also can discharge 160 DEG C～the high-temperature flue gas of 200 DEG C after main heat exchanger.High-temperature flue gas is discharged in air after flowing to the fume collecting chamber of gas module, smoke collection pipe by air-introduced machine.Even, the exhaust gas temperature of conventional boiler is even as high as more than 250 DEG C, and energy loss is big.
For above-mentioned, generally also can absorb the part sensible heat in high-temperature flue gas with retracting device, but owing to being limited by retracting device structure and material, exhaust gas temperature all drops less than condensation temperature.It is clear that the sensible heat in high-temperature flue gas does not make full use of.The more important thing is: the superheated vapour in high-temperature flue gas can condense when dropping to condensation temperature and discharge substantial amounts of latent heat then entirely without utilization, and therefore, the thermal efficiency can only achieve 86%～90%, and same energy loss is big.

Therefore, in order to ensure the normal work and use life-span of gas module, the exhaust temperature of flue gas cannot be below 150 DEG C, which limits the further raising of gas module furnace thermal efficiency.Further, the water (such as natural gas CH4+2O2=CO2+2H2O) produced during fuel combustion, when high temperature discharge, is to be discharged in air with the form of acid superheated vapour equally, and this not only can give environment, also can aggravate the greenhouse effect of the earth.
At present, condensed type combustion gas module furnace is the mode utilizing heating water return condensation heat exchange, absorb the sensible heat in flue gas and the latent heat preboiler backwater of steam coagulation precipitation, but in the actual application of building heating, owing to being restricted by heating water return lowest temperature, utilizing heating water return condensation heat exchange, the exhaust gas temperature of module boiler typically can only drop to 80 DEG C to 60 DEG C, it is clear that sensible heat and latent heat in flue gas the most do not make full use of.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, a kind of efficiently double-condensing gas module stove is provided, it is by preheating heating water return condensation heat exchange and preheated air condensation heat exchange two ways simultaneously, more make full use of the sensible heat in boiler exhaust gas and latent heat, improving the thermal efficiency of gas module stove, exhaust gas temperature can drop to less than 40 DEG C, and boiler thermal output reaches 105%, and by differently configured technology, nitrogen oxides (NOX) discharge capacity can drop to 70mg/m～30mg/m, there is preferable effects of energy conservation and environmental protection.
