Abstract

The utility model discloses an energy-saving oil and gas fired boiler. The energy-saving oil and gas fired boiler comprises a burner, a safety assembly, a base, a boiler shell, a boiler furnace in the boiler shell, one, two or more return-stroke smoke pipes, a smoke chamber connected with the boiler furnace and a first return-stroke flue pipe, a smoke exhausting box connected with a tail-return-stroke smoke pipe and a chimney, a connecting smoke box among the return-stroke smoke pipes, and a heat-absorbing medium in the boiler shell, wherein a heat-absorbing medium sleeve is arranged on the wall of the smoke exhaust box; a hot heat-absorbing medium outlet in the upper end of the heat-absorbing medium sleeve is connected with the boiler shell, and a cold heat-absorbing medium inlet in the lower end of the heat-absorbing medium sleeve is connected with a return heat-absorbing medium port formed in the wall of the boiler shell; a plurality of heat-absorbing medium pipes which are communicated with the heat-absorbing medium sleeve and incline upwards towards the hot heat-absorbing medium outlet are fixed in the smoke exhaust box. The energy-saving oil and gas fired boiler has the advantages of low temperature of flue gas exhausted from the chimney, high heat exchange efficiency, over 97 percent of the thermal efficiency of the boiler, saving of energy, reduction of the environmental pollution, simple structure, relatively low cost and long service life.

Description

A kind of energy-conservation gas fuel boiler
Technical field
The utility model belongs to burning boiler equipment technical field, particularly a kind of gas fuel boiler.
Background technology
The oil-burning gas-fired boiler using is at present generally by the flue in burner, shell, shell, a backhaul, two backhauls or many backhauls smoke pipe, connect the smoke-box of flue and the first backhaul smoke pipe, connect the smoke box of last backhaul smoke pipe and chimney, the heat-absorbing medium that the connection smoke box between each backhaul smoke pipe and shell are full of.In order to ensure the burning of gas or oil, need to ensure that furnace wall has higher temperature, like this, the flue-gas temperature that flows into chimney is just very high, can reach more than 180 DEG C, and the flue-gas temperature of namely getting rid of is very high, and not only contaminated environment, also forms the waste of the energy.
Utility model content
The purpose of this utility model solves the above-mentioned problems in the prior art exactly, and the flue-gas temperature that provides a kind of chimney to discharge is low, and heat exchange efficiency is high, saves the energy-conservation gas fuel boiler of the energy.
For achieving the above object, technical solution of the present utility model is: a kind of energy-conservation gas fuel boiler, and it comprises burner, security component, base, shell, the flue in shell, a backhaul, two backhauls or many backhauls smoke pipe, connect the smoke-box of flue and the first backhaul smoke pipe, connect the smoking box of last backhaul smoke pipe and chimney, the connection smoke box between each backhaul smoke pipe, the heat-absorbing medium that shell is full of; On smoke evacuation tank wall, have heat-absorbing medium cover, the hot heat-absorbing medium outlet in upper end of this heat-absorbing medium cover is connected with shell, and the enfleurage thermal medium import of lower end connects the resorption thermal medium mouth being arranged on shell wall; In smoking box, be fixed with multiple acclivitous heat-absorbing medium pipes of thermotropism heat-absorbing medium Way out that are connected with heat-absorbing medium cover.
Burner described above is fully automatic burner.Adopt fully automatic burner, safe, workload is little, load adjustment is flexible.
On the outer wall of heat-absorbing medium pipe described above, be distributed with multiple fins, to increase its endotherm area.
Flue described above is corrugated flue, energy absorbing thermal expansion, and Strength Safety is higher.
Because the utility model smoking box is set to waste-heat recovery device, the flue gas entering before chimney is carried out to waste heat recovery, make the flue-gas temperature that gives off low, exhaust gas temperature is minimum to be reached below 100 DEG C, not only save the energy, the thermal pollution of also having avoided high-temperature flue gas to cause environment; The heat-absorbing medium entering in shell has been carried out to preheating simultaneously, followed the position low in flue-gas temperature, heat-absorbing medium temperature is lower, at the high high medium of position set temperature of flue-gas temperature, always make to keep temperature difference multiplying power between high-temperature flue gas and heat-absorbing medium, it is the highest that heat exchange efficiency reaches.In a word, the flue-gas temperature that the utility model chimney is discharged is low, and heat exchange efficiency is high, and boiler thermal output can reach more than 97%, has saved the energy, has reduced environmental pollution, and simple in structure, and cost is relatively low, long service life.
Brief description of the drawings
Fig. 1 is left view of the present utility model;
Fig. 2 is the AA cutaway view of Fig. 1.
Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the utility model is further described.
As depicted in figs. 1 and 2, the present embodiment is atmospheric gas oil-fired water-boiler, and it comprises fully automatic burner 17, security component: the explosion-protection equipment on atmospheric air port 20 and the burner having on shell 2 upper surfaces, base 1, shell 2, flue 4, the two backhaul smoke pipes 9,18 in shell, connect the smoke-box 13 of flue 4 and the first backhaul smoke pipe 9, connect the smoking box 11 of the second backhaul smoke pipe 18 and chimney, the connection smoke box 8 between each backhaul smoke pipe 9,18, the heat-absorbing medium being full of in shell 2: water.Flue 4 is like corrugated flue (can be also non-corrugated flue).On smoking box 11 walls, there is heat-absorbing medium cover: water jacket 22, the upper end hot water outlet of this water jacket 22 is connected with shell 2, and the cooling water inlet of lower end connects the water return outlet 21 being arranged on shell 2 walls.In smoking box 11, be welded with multiple be connected with water jacket 22 to the acclivitous heat-absorbing medium pipe of hot water outlet direction: water pipe 10.3 is the heat-insulation layer of shell 2 outsides, and 6 is the interface of fully automatic burner 17, and 12 is the outlet flue of smoking box 11, and this outlet flue 12 connects chimney, and 16 is sewage draining exit, and 19 is hot water outlet, and 5 is flame retardant coating.
Also pressure hot water boiler of the atmospheric gas oil-fired water-boiler of above-described embodiment; Burner also can be manual burner; Smoke pipe can be set to single backhaul smoke pipe, three backhaul smoke pipes, four backhaul smoke pipes etc. as required, other heat-conducting medium outside heat-absorbing medium also dewaters.It is all covered by the protection domain of this patent.
