Description

A kind of Waste Heat Recovery integrates side fish stove
Technical field
The present invention relates to field of waste heat recovery, more particularly to a kind of Waste Heat Recovery to integrate side fish stove.
Background technology
According to statistics, existing catering trade gas-cooker is due to serious heat loss, and sky burning phenomenon is universal, and its average thermal efficiency is only 20%, thermal loss is up to 80%, causes great energy waste.The thermal efficiency of so-called gas-cooker, it is exactly generally to fire Gas kitchen is in use to the effective rate of utilization of gas thermal energy.As can be seen that household gas range from the thermal efficiency of gas-cooker In the prevalence of the not high phenomenon of gas thermal energy utilization rate, the gas thermal energy for having about 40~50% is wasted tool in use. Used commercial gas kitchen range on Vehicles Collected from Market, its combustion system still use traditional open combustion system of malleation, combustion In gas combustion process combustion flame and high-temperature flue gas are directly leaked so as to be formed after fuel gas buring a large amount of unburnt High-carbon gas is directly discharged into surrounding environment, so that heat caused by fuel gas buring only has a small part to be utilized by pan, Efficiency of utilization is extremely low.And due to that will bring atmosphere pollution and noise dirty in imperfect combustion combustion gas release and surrounding environment Dye.Therefore, either household gas utensils or commercial gas kitchen range all suffer from energy significant wastage in use Serious problems.
Following patent document is can be found that by the retrieval to gas-cooker recuperation of heat prior art:
Applicant Hefei Shunchang distributed energy comprehensive application technology Co., Ltd discloses a series of commercial gas pots and stoves Fume waste heat retracting device, including retracting device, hot water supply system, unpowered recovery system etc., including shell, the shell Inner vertical water inlet manifold and outfall sewer be installed, water inlet manifold is arranged on the right-hand member of shell, outfall sewer is arranged on The left end of shell, the bottom of water inlet manifold are provided with water inlet pipe, outlet pipe, water inlet pipe and water outlet are provided with the top of outfall sewer Manually-operated gate is fitted with pipe, square finned tube is installed between water inlet manifold and outfall sewer, installed on square finned tube There is fin.But the configuration of its structure is complicated, inconvenience is controlled during use, it is inefficient, it can not maximize and effectively utilize used heat Energy.
Applicant's gold dollar leather discloses a kind of commercial gas-fired stove residual heat using device, is by water-jacket typ burner hearth, storage tank, stove Thorax water inlet pipe, burner hearth outlet pipe, flowing water Valve, ball-cock assembly, cold water inlet composition.It is characterized in that there are water-jacket typ burner hearth, water-jacket typ The hearth wall of burner hearth is hollow-core construction, and internal water storage forms water jacket structure, so as to realize the circulating-heating to water in water tank, has The collection fuel gas buring of effect is lost to the heat on burner hearth.But it is only through heat exchange and takes heat from gas-cooker periphery to In water tank, partial heat once focuses on more, and heat exchange efficiency necessarily declines, very inconvenient in actual use.
Applicant Nanjing Jin Gong kitchen tool apparatus Co., Ltd discloses a kind of commercial gas-fired stove for realizing flue gas waste heat recovery, Including the kitchen range top, flue gas waste heat recovery apparatus, the combustion gas branch road being connected with the kitchen range top, by the flue gas waste heat recovery apparatus and stove The air passage and flue gas branch road that platform links together.Wherein flue gas branch road passes through flue gas waste heat recovery apparatus phase with air passage Mutual interconnection, flue gas are exchanged heat with air, and air themperature is lifted while heat loss due to exhaust gas is reduced, and realization enters combustion gas The air preheat of stove burning, so as to improve fuel gas buring efficiency, energy-saving effect is notable.Flue gas waste heat recovery apparatus is a stainless steel The plate type heat exchanger of material, pressure drop are less than 20Pa, and surface is using salient point increase disturbance and heat exchange area, compact-sized, modularization Design be mountable in the smoke discharging pipe of gas-cooker.It is to be exchanged heat using flue gas and air by Btu utilization to air inlet Among air, the heating to inlet air is realized so as to improve the thermal efficiency, but this gas converting heat heat exchanging device requires higher, Actual heat transfer effect is unsatisfactory.
Therefore, in face of these problems, it is necessary to prior art is improved, realizes that one kind can maximize and realizes combustion gas The system that stove waste gas Waste Heat Recovery recycles, it can carry out the regulation of recuperation of heat according to the actual requirements, improve gas-cooker and use In energy-efficient performance, people is directly benefited from saving in combustion gas, and effective utilization for combustion gas resource and The protection of environmental resource all has important practical significance.
