Abstract
The invention relates to a waste heat recovery gas boiler which comprises a gas boiler body. The gas boiler body is provided with a tail gas outlet which is sequentially connected with an energy saver, a waste heat recovery device, a diverter and a draught fan through a pipeline. The diverter is further connected with a chimney through the pipeline. According to the waste heat recovery gas boiler provided by the invention, tail gas waste heat of the gas boiler is recycled by means of a steam generator or a hot water heat exchanger, and the problem that the pressure head of the system is damaged caused by large tail gas resistance of the combustion system is solved through the draught fan, so that the waste heat recovery gas boiler is simple in structure and is practical.
Description
Technical field
The present invention relates to a kind of gas fired-boiler, relate in particular to a kind of gas fired-boiler with waste heat recovery.
Background technology
Gas fired-boiler is as the term suggests refer to the boiler that fuel is combustion gas, and gas fired-boiler and oil burning boiler, electric boiler are most economical by comparison, so most of people have selected gas fired-boiler.
And in routine use, the tail gas of gas fired-boiler directly discharges, cause a large amount of energy loss, and some baroque exhaust waste heat recovery devices, cost is higher, simultaneously, also can so that the tail gas resistance increment of gas burning system, can cause the loss in head of whole system if directly add some exhaust waste heat recovery devices.
Summary of the invention
The technical problem to be solved in the present invention is: directly discharge energy waste in order to solve gas fired-boiler tail gas, baroque exhaust waste heat recovery device, cost is too high again, can cause gas burning system tail gas resistance increment and directly add exhaust waste heat recovery device, the problem of loss in head the invention provides a kind of gas fired-boiler with waste heat recovery and solves the problems referred to above.
The technical solution adopted for the present invention to solve the technical problems is: a kind of gas fired-boiler with waste heat recovery, comprise gas fired-boiler, described gas fired-boiler has the tail gas outlet, the outlet of described tail gas is connected with energy-saving appliance, waste-heat recovery device, current divider and air-introduced machine in turn by pipeline, also being connected with chimney by pipeline of described current divider.
Embodiment 1: described waste-heat recovery device is steam generator.
Embodiment 2: described waste-heat recovery device is hot water heat exchanger.
The invention has the beneficial effects as follows, a kind of gas fired-boiler with waste heat recovery of the present invention, utilize steam generator or hot water heat exchanger, realize the recycling of gas fired-boiler using waste heat from tail gas, solved the problem that combustion system tail gas resistance causes system head to lose greatly by air-introduced machine, simple in structure, be suitable for practicality.
Description of drawings
The present invention is further described below in conjunction with drawings and Examples.
Fig. 1 is the structural representation that the present invention has the optimum embodiment of gas fired-boiler of waste heat recovery.
Among the figure 1, gas fired-boiler, 2, energy-saving appliance, 3, waste-heat recovery device, 4, current divider, 5, air-introduced machine, 6, chimney.
The specific embodiment
In conjunction with the accompanying drawings, the present invention is further detailed explanation.These accompanying drawings are the schematic diagram of simplification, basic structure of the present invention only is described in a schematic way, so it only show the formation relevant with the present invention.
As shown in Figure 1, a kind of gas fired-boiler with waste heat recovery of the present invention, comprise gas fired-boiler main body 1, gas fired-boiler main body 1 has the tail gas outlet, tail gas outlet is connected with energy-saving appliance 2, waste-heat recovery device 3, current divider 4 and air-introduced machine 5 in turn by pipeline, current divider 4 also are connected connection with chimney by pipeline.
Embodiment 1: waste-heat recovery device 3 is steam generator.
Embodiment 2: waste-heat recovery device 3 is hot water heat exchanger.
Take above-mentioned foundation desirable embodiment of the present invention as enlightenment, by above-mentioned description, the relevant staff can in the scope that does not depart from this invention technological thought, carry out various change and modification fully.The technical scope of this invention is not limited to the content on the specification, must determine its technical scope according to the claim scope.
