Abstract

The utility model relates to a WNS4-1.O-Q type gas boiler, in particular to a gas steam boiler with a low-level eccentric furnace, which is fine in heat exchange effect and ideal in heat transfer capacity of unit area or volume, increases heat efficiency and meets development idea of energy conservation and emission reduction. The gas steam boiler is characterized by at least comprising a boiler barrel, an internal corrugated furnace and a threaded smoke tube, the corrugated furnace is eccentrically arranged on the lower portion of the boiler barrel, and the gas steam boiler further consists of auricular reversal chambers which are symmetrically arranged on two sides of the corrugated furnace, thereby increasing steam space, expanding convection heating surfaces, increasing steam quality and improving boiler heat efficiency. The gas steam boiler is novel and reasonable in structure.

Description

The eccentric low position type combustion and steam of flue boiler

Technical field

The utility model relates to WNS4-1.0-Q type gas fired-boiler, and heat exchange effect is good, and the heat output ideal of unit are or volume has improved the thermal efficiency, meets the eccentric low position type combustion and steam of a kind of flue boiler of energy-saving and emission-reduction idea of development.

Background technology

Existing gas fired-boiler blowdown heat loss about 1%, body of heater heat radiation 1-2%, imperfect combustion 1%, evenly heat efficient is about about 87%, and nearly 10% heat energy is discharged to by boiler exhaust gas and gone in the atmosphere, and simultaneously, exhaust gas temperature is up to 180 ℃-250 ℃, both waste the energy in a large number, 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 needs to consume the natural gas of Nm3 more than 80, produces the flue gas of 1300Nm3 simultaneously, steam comprising 15%-19%, there is part steam to be in superheat state, and can not in high-temperature flue, condenses into liquid water and emit the latent heat of vaporization, this part the 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%, so the flue gas calorific value is very big.Therefore, along with the continuous progress of science and technology and the continual renovation of product are regenerated, how effectively to reduce the residual heat from boiler fume loss, the thermal efficiency that improves boiler is the important topic of pendulum in field of boilers.

Summary of the invention

Technical problem to be solved in the utility model is to provide the eccentric low position type combustion and steam of a kind of flue boiler, the safety level scope of boiler is increased, can reduce the harm of lack of water accident to greatest extent, can also enlarge the steam chest space, to improve steam quality and boiler thermal output.

The technical solution of the utility model: construct the eccentric low position type combustion and steam of a kind of flue boiler, it is characterized in that, at least comprise drum and built-in corrugated flue and screw thread pyrotechnics pipe thereof, and, described corrugated flue is the bottom that off-centre is arranged at described drum, also comprises being the ear shape that the is symmetricly set in described corrugated flue both sides chamber of strile-bacing.Increase the vapor space, enlarged convection heating surface, improved steam quality, thereby improved boiler thermal output.

The eccentric low position type combustion and steam of the flue that provides according to the utility model boiler is characterized in that, described screw thread pyrotechnics Guan Chenger shape is arranged in described ear shape and strile-backs in the chamber, and the strile-back intrados of chamber of described ear shape is matched with the both sides of described corrugated flue.When concrete the use, carry out augmentation of heat transfer, can increase heat transfer area greatly.

Realize the eccentric low position type combustion and steam of flue of the present utility model boiler, have following advantage: structure is novel, and is rational in infrastructure, improved the thermal efficiency, heat-transfer effect is better, exhaust gas temperature is low, sufficient combustion, fuel saving, reduce pollution characteristics, and the employing full-automatic regulation, and it is simple to operate, also meet the sustainable development view of energy-saving and emission-reduction.

The specific embodiment

The eccentric low position type combustion and steam of flue as shown in Figure 1 and Figure 2 boiler, at least comprise drum 1 and built-in corrugated flue 2 and screw thread pyrotechnics pipe 5 thereof, and corrugated flue 2 is the bottom that off-centre is arranged at drum 1, also comprises being the ear shape that the is symmetricly set in corrugated flue 2 both sides chamber 3 of strile-bacing.Screw thread pyrotechnics pipe 5 is ear shape and is arranged in ear shape and strile-backs in the chamber 3, and the strile-back intrados of chamber 3 of ear shape is matched with the both sides of corrugated flue 2, with reference to as shown in Figure 2.

The eccentric low position type combustion and steam of flue of the present utility model boiler, make second backhaul be heated the pyrotechnics pipe better with drum in water at low temperature carry out heat exchange, enlarged convection heating surface, be fit to the natural gas fuel of combustion high heating value, and the product after the burning is a clean air, non-secondary pollution.Help efficient heat transfer, heating surface area is big, and heat-transfer effect is good, the foot of exerting oneself, and exhaust gas temperature is low.Make flame produce strong disturbance, make sufficient combustion, improve heat transfer coefficient greatly, reduce exhaust gas temperature, 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, has improved the thermal efficiency of the utility model boiler.
