Abstract
The utility model provides a gas boiler and a thermal cycling device, comprising a water inlet and a water outlet on a boiler body, a burner at the front end of the boiler body, a condensing heat exchanger that is arranged in a smokebox at the rear end of the boiler body and is circularly connected with a hot water tank outside the boiler body, and water tubes communicated with the water inlet and the water outlet of the boiler body is also internally and circularly connected through the hot water tank. The condensing heat exchanger is arranged in the smokebox at the rear end of the boiler, which can not only reduce the temperature of flue gas, but also condense the steam in the flue gas. The utility model recovers the sensible heat in the flue gas and the condensation latent heat in the steam, reduces the temperature of the flue gas to 50 to 70 DEG C, the boiler efficiency is improved by 10 percent to 15 percent; because of the condensation of the steam, the SO2 and SO3 in the flue gas can be separated, thereby reaching the requirement of environmental protection.
Description
Technical field
The utility model belongs to boiler plant, is the improvement to existing hot-water boiler, specifically a kind of gas fired-boiler and thermocirculator.
Background technology
In the conventional boiler, exhaust gas temperature is generally at 160～250 ℃, and the water vapour in the flue gas still is in superheat state, can not condense into liquid water and emit the latent heat of vaporization, so the conventional boiler thermal efficiency generally can only reach 87%～91%.Be fully to reduce flue-gas temperature, improve boiler efficiency, people generally adopt the way of increase along the road backhaul, or in the way that exhanst gas outlet is installed condenser, improve absorbing of heat in the flue gas, the particularly DeGrain of condensed water comprehensive utilization.
Summary of the invention
The utility model is exactly in order to overcome the defective in the above-mentioned technology, provide a kind of in reducing the process of flue-gas temperature with the water vapor condensation in the flue gas, the latent heat of vaporization wherein is fully utilized, thereby improves the gas fired-boiler and the thermocirculator of the thermal efficiency and condensed water comprehensive utilization.
The purpose of this utility model is achieved through the following technical solutions: a kind of gas fired-boiler and thermocirculator, be included in the entery and delivery port on the boiler body 2, the burner 1 of boiler body 2 front ends, it is characterized in that condensing heat exchanger 3 is installed in the smoke box of boiler body 2 rear ends, and be connected with body of heater boiler 5 circulations outward; The water pipe that is communicated with boiler body 2 entery and delivery ports also connects by circulation in the boiler 5.
Can fully reclaim the sensible heat in the flue gas and the latent heat of condensation of water vapour, can be reduced to 50～70 ℃ to exhaust gas temperature, the comparable conventional boiler of boiler efficiency improves 10%～15%, therefore, the boiler efficiency of calculating by the fuel low heat value can reach 100%, even surpass 100%, and because the condensation of water vapour, can be with the SO in the flue gas
2, SO
3Separate, avoided environmental pollution.
The delivery port of condensing heat exchanger 3 connects boiler 5 by water pipe; One end of condensed water circulating pump 4 connects boiler 5, and the other end connects the water inlet of condensing heat exchanger 3.The condensed water intensification back that has absorbed fume afterheat flows in the boiler 5, is used for domestic water.
The water pipe that connects boiler body 2 entery and delivery ports is coiled in the boiler 5.Utilize the condensed water that has certain heat in the hot water heat hot water tank 5 of boiler body 2, to guarantee the requirement of domestic water.
An end that is coiled in boiler 5 inner conduits connects and divides water vat 8, the delivery port that divides water vat 8 to be communicated with on the boiler body 2; The water inlet that the other end of water pipe connects the cylinder 7 that catchments, the cylinder 7 that catchments is communicated with on the boiler body 2.Can realize controlling the temperature requirement of boiler 5.
The outlet pipe of condensing heat exchanger 3 connects expansion tank 9.Formed the whole system of heat integration.
The domestic water circulating water pipe is housed on the boiler 5, and its circulating water pipe connects the domestic water load; Load goes into the domestic water circulating pump is housed in the water loop.Form a hot water supply area among a small circle.
The utility model has the advantages that: condensing heat exchanger is installed in the smoke box of boiler rear end, not only can reduce the temperature of flue gas, water vapour in all right condensation flue gas, the sensible heat in the flue gas and the latent heat of condensation of water vapour have fully been reclaimed, can be reduced to 50～70 ℃ to exhaust gas temperature, the comparable conventional boiler of boiler efficiency improves 10%～15%, and because the condensation of water vapour, can be with the SO in the flue gas
2, SO
3Separate, reach environmental requirement.
