Abstract
The utility model relates to a WNS6-1.0-Q type gas fired boiler, which has the characteristics of sufficient combustion, small dust discharge concentration, large heated area, good heat transfer effect and the like. Thereby, the utility model belongs to the novel gas fired steam boiler with the advantages of energy source saving, pollution reduction, smoke discharge temperature reduction and heat efficiency improvement. The utility model is characterized in that the novel gas fired steam boiler at least comprises a boiler tube and a wave-shaped furnace liner arranged in the boiler tube, wherein the wave-shaped furnace liner is arranged at the lower part of the boiler tube in an eccentric way, symmetrical ear-shaped combustion chambers are arranged at both sides of the wave-shaped furnace liner, and in addition, a plurality of threaded smoke fire pipes are arranged in the ear-shaped combustion returning chambers. The conversion heated surface is enlarged, the heat exchange is perfectly carried out with low-temperature water in the boiler tube, the heat efficiency of the boiler is improved, the safety water level range of the steam boiler is enlarged, and the harm of water lack accidents can be reduced to the furthest degree, the wave-shaped furnace liner is possibly distributed in a position at the bottom part of the boiler tube, the steam space is enlarged, and the steam quality is improved.
Description
Technical field
The utility model relates to WNS6-1.0-Q type gas fired-boiler, have characteristics such as sufficient combustion, smoke dust discharge concentration is little, heating surface area is big, heat-transfer effect is good, thereby energy savings, reduce to pollute, reduce exhaust gas temperature, improve a kind of novel gas steam boiler of the thermal efficiency.
Background technology
At present, in general, the gas fired-boiler heat loss due to exhaust gas is about 8%-16%, blowdown heat loss about 1%, body of heater heat radiation 1-2%, imperfect combustion 1%, the evenly heat efficient of existing domestic combustion and steam boiler is about about 87%, wherein, comprise and adopt the strile-back boiler of chamber of little tube sheet, and nearly 10% heat energy is discharged to by boiler exhaust gas and has gone in the atmosphere, simultaneously, exhaust gas temperature had both been wasted the energy in a large number up to 180 ℃-250 ℃, caused the serious environmental thermal pollution again.Moreover, 1 ton of steam of the every generation of the part gas fired-boiler of existing market, approximately need to consume the natural gas of Nm3 more than 80, produce the flue gas of 1300Nm3 simultaneously, water vapour comprising 15%-19%, there is the part water vapour to be in superheat state, and can not in high-temperature flue, condense into liquid water and emit the latent heat of vaporization, this part latent heat enormous amount in the flue gas can reach kcal more than 5.6 ten thousand, account for natural gas low heat valve about 6%, because the flue gas calorific value is very big, only the latent heat of vaporization of water vapour just is enough to boiler feedwater is preheating to more than 100 ℃, not only can be used for boiler replenishing water, and unnecessary hot water also can be used to heating life hot water.Therefore, along with the continual renovation of the continuous progress of science and technology and product is regenerated, how to improve the thermal efficiency of boiler, effectively reduce residual heat from boiler fume, reduce that to pollute be the important topic that solves current boiler energy-saving emission-reduction.
Summary of the invention
Technical problem to be solved in the utility model is to provide a kind of novel gas steam boiler, increases convection heating surface, improves heat-transfer effect, reduces fume afterheat, to improve boiler thermal output, reduces fuel cost, and demonstrates fully the characteristics of environmental protection and energy saving.
The technical solution of the utility model: construct a kind of novel gas steam boiler, at least comprise drum and built-in flue thereof, it is characterized in that, at least comprise drum and built-in corrugated flue thereof, described corrugated flue is the bottom that off-centre is arranged at described drum, and the ear shape that is provided with symmetry in the both sides of the described corrugated flue chamber of strile-bacing, and in strile-bacing the chamber, described ear shape is provided with some screw thread pyrotechnics pipes.Increased convection heating surface, better with drum in water at low temperature carry out heat exchange, improved boiler thermal output; The safety level scope of steam boiler is increased, can reduce the harm of lack of water accident to greatest extent; Still more, corrugated flue can be arranged in the boiler drum bottom position as far as possible, therefore, has increased the vapor space, has improved steam quality.
The novel gas steam boiler that provides according to the utility model, it is characterized in that, described screw thread pyrotechnics pipe strile-backs respectively at described ear shape and is ear shape in the chamber and arranges, and, the described screw thread pyrotechnics pipe quantity of described corrugated flue both sides equates, the strile-back intrados of chamber of ear shape cooperates respectively with the both sides of corrugated flue.Carry out augmentation of heat transfer, can increase heat transfer area greatly, heat-transfer effect is good, sufficient combustion, and smoke dust discharge concentration is little, and exhaust gas temperature is low, and energy savings reduces and pollutes.
Realize a kind of novel gas steam boiler of the present utility model; have following advantage: thermal efficiency height, increased the vapor space, improved steam quality; not only saved the energy; also protect environment, adopted full-automatic regulation, the automaticity height; simple to operate; structure is novel, and is rational in infrastructure, meets the Scientific Outlook on Development of energy-saving and emission-reduction.

Fig. 2 is the left TV structure schematic diagram of the utility model Fig. 1.
The specific embodiment
A kind of novel gas steam boiler as shown in Figure 1 and Figure 2, at least comprise drum 1 and built-in corrugated flue 2 thereof, corrugated flue 2 is the bottom that off-centre is arranged at drum 1, and the ear shape that is provided with symmetry in the both sides of corrugated flue 2 chamber 3 of strile-bacing, and in strile-bacing chamber 3, ear shape is provided with some screw thread pyrotechnics pipes 5.Screw thread pyrotechnics pipe 5 strile-backs respectively at ear shape and is ear shape in the chamber 3 and arranges, and the quantity of the screw thread pyrotechnics pipe 5 of corrugated flue 2 both sides equates, the strile-back intrados of chamber 3 of ear shape cooperates respectively with the both sides of corrugated flue 2, and reference is shown in Figure 2.
A kind of novel gas steam boiler of the present utility model by full-automatic regulation, makes sufficient combustion, and fuel saving has been saved the energy in a large number, simultaneously, because the natural gas sulfur content is seldom, SO in the flue gas
2Content is very low, and the overwhelming majority all has been dissolved in the flue gas condensing water and has discharged, and effectively reduces pollution.The more important thing is and improved boiler thermal output, enlarged convection heating surface, help energy savings; The safety level scope of steam boiler is increased; sufficient combustion; no flue dust, noiseless, smoke dust discharge concentration is all less than 20mg/Nm3; sulfur dioxide emissioning concentration is all less than 200mg/Nm3; the pertinent regulations that meet JB13271-2002 " emission standard of air pollutants for boilers ", the natural gas fuel of the most suitable combustion high heating value, and the product after the burning is a clean air; non-secondary pollution helps environmental protection.
