Abstract

The utility model discloses a gas-and-oil-fired boiler with sufficient burning. The gas-and-oil-fired boiler comprises a combustor, a safety component, a base, a boiler shell, a boiler furnace in the boiler shell, one, two or more return stroke smoke tubes, a smoke chamber connected with the boiler furnace and a first return stroke smoke tube, a smoke discharge box connected with the last return stroke smoke tube and a chimney, connecting smoke boxes among the return stroke smoke tubes, and a heat absorptive medium filled in the boiler shell, wherein the boiler furnace is in the shape similar to a wave of which the peak is a part of a sine curve and the bottom surface of a valley is a plane, and the valley is much wider than the peak; a flame retardant layer capable of covering the peak and the valley is fixed on the inner wall of the boiler furnace; a plurality of heat transfer needles that penetrate the flame retardant layer are fixed on the inner wall of the boiler furnace at the valley. The gas-and-oil-fired boiler with sufficient burning disclosed by the utility model is high in heat transfer efficiency, specifically at least 97%, relatively low in temperature of smoke discharged by the chimney, energy-saving, reduced in environmental pollution, simple in structure, low in cost, and long in service life.

Description

A kind of gas fuel boiler of sufficient combustion
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; Flue is uniformly distributed waveform or the non-waveform of crest and trough.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; If reduction exhaust gas temperature, the temperature of furnace wall also can reduce, and causes gas or oil firing in flue insufficient, and over-emitting black exhaust, has not only caused the waste of the energy, the harmful substance that black smoke contains contaminated environment in the same old way.And inboard wall of furnace is directly burnt by high temperature, its life-span is short.
Utility model content
The purpose of this utility model solves the above-mentioned problems in the prior art exactly, provides a kind of gas or oil firing abundant, and heat energy transformation efficiency is high, long service life, and the gas fuel boiler of the chimney relatively low sufficient combustion of flue-gas temperature of discharging.
For achieving the above object, technical solution of the present utility model is: a kind of gas fuel boiler of sufficient combustion, 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; Flue is like corrugated flue, crest is a sinusoidal part, and the bottom surface of trough is plane, and trough is far wider than crest, on inboard wall of furnace, be fixed with the flame retardant coating that one deck can hide Wave crest and wave trough, on the inboard wall of furnace at trough place, be fixed with multiple heat transfer pins that penetrate flame retardant coating.
Burner described above is fully automatic burner.Adopt fully automatic burner, safe, workload is little, load adjustment is flexible.
Heat transfer pin described above is carbon steel heat transfer pin or stainless steel heat transfer pin, and its heat-transfer effect is good, and cost is low.
Because the utility model has increased flame retardant coating on inboard wall of furnace, the anti-barbecue ability of flame retardant coating is strong, it has not only prevented that its furnace wall is subject to the direct barbecue of high temp fire and reduces service life, and the heat-transfer effect of flame retardant coating is poor, can make the gas of burning in flue or temperature and the heat-absorbing medium of oil separated, in the time that the flue gas that makes to discharge reaches lower temperature, make gas or oil keep higher temperature, make its combustion efficiency better, what burn is more abundant, thermal conversion efficiency is the highest, no longer produces black smoke, has reduced the generation of pernicious gas simultaneously; Heat transfer pin on inboard wall of furnace has ensured that again the heat that gas or oil firing produce directly passes to heat-absorbing medium, makes heat exchange efficiency of the present utility model high.Its corrugated flue, energy absorbing thermal expansion, Strength Safety is higher.In a word, thermal transition efficiency of the present utility model is high, can reach more than 97%, and the flue-gas temperature that chimney is discharged is relatively low; Save the energy, reduced environmental pollution, and simple in structure, cost is 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, crest 15 is a sinusoidal part, the bottom surface of trough 14 is plane, and trough 14 is far wider than crest 15, on flue 4 inwalls, be adhesively fixed with the flame retardant coating 5 that one deck can hide crest 15, trough 14, on flue 4 inwalls at trough 14 places, be welded with multiple carbon steel heat transfer pins 7 that penetrate flame retardant coating 5.3 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 21 is water return outlet.
Also pressure hot water boiler of the atmospheric gas oil-fired water-boiler of above-described embodiment; Burner also can be manual burner; Carbon steel also can be the heat transfer pin of other material; 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.
