Background technology

Existing water-storage heater, as China's patent No. is 200920108310.x, it is a kind of immersion water heater, it is by burner, the burning cylindrical shell, end cover interlayer, the awl cap, heat exchanger tube, jet head sets, the impeller current divider, exhaust opening, dewater unit, bolt, water inlet pipe, outlet pipe, relief valve, burner hearth, the spraying part flow arrangement, Heat Room and water jacket are formed, described spraying part flow arrangement is discoid cylindrical shell, the upper end, middle part of discoid cylindrical shell communicates with water inlet pipe, spacing distance is provided with 4-12 and crosses water pipe on the side perisporium of discoid cylindrical shell, each is crossed and is connected to fog-spray nozzle on the water pipe, described dewater unit bottom is a funnelform funnel dish, the upper end-face edge of funnel dish is provided with ring-shaped baffle, and spacing distance is provided with shredded tobacco for water pipes and enters the hole on the ring-shaped baffle.Its weak point is: one, atmosphere direct combustion formula burner, and flame is long, has increased the volume of combustion barrel and boiler; Flame divides three parts, and outer light is the high-temperature region, can reach more than 1500 ℃, easily produces nitrogen oxide, and the internal layer anoxycausis easily produces carbon monoxide, and is unfavorable to discharging; It is little to regulate the large and small fire scope in addition, and poor stability influences efficiency of combustion.Two, flue gas mixes undesirable with the water smoke of spray.Three, Pen Lin insufficient strength, exhaust gas temperature is higher.Four, exhaust opening fog is bigger, and water smoke escape loss is bigger.

Summary of the invention

The purpose of this utility model is to overcome the deficiencies in the prior art, has adopted a kind of full premix metallic fiber combustor, has set up flue gas cyclone, moisture trap, one deck shower nozzle.

The purpose of this utility model is achieved in that this spray condensing gas water-heating furnace mainly is made up of moisture trap, heat exchange bucket, nozzle component, waterproof awl cap, flue gas cyclone, combustion barrel bend pipe, header tank and full premix metallic fiber combustor etc.Full premix metallic fiber combustor and combustion barrel bend pipe are separately fixed at the interior outside of the same sidewall of header tank.Waterproof awl cap and flue gas cyclone are fixed on the upper end of combustion barrel bend pipe.Nozzle component is fixed on the heat exchange bucket by angle steel, which is provided with water inlet.The heat exchange bucket is by being bolted on the header tank, and moisture trap is fixed on the exhaust outlet of heat exchange bucket, is respectively equipped with outlet pipe and blow-off pipe on the header tank.

Nozzle component is two-layer by compositions such as nozzle, communicating pipe and spraying part flow arrangements.On the spraying part flow arrangement be housed 8～16 communicating pipe, nozzle is equipped with in the end of communicating pipe.The pressurization backwater that enters from water inlet through the spraying part flow arrangement, communicating pipe enter nozzle, be vaporific and spray in the heat exchange bucket, and become high-temperature-hot-water to fall into header tank after the high-temperature flue gas heat exchange.

Advantage of the present utility model: the one, adopted full premix metallic fiber combustor.This is present state-of-the-art gas burner system.Accurate metering and proportioning, mixing, the metallic fiber Cheng Weiyan burning of so closing permeation high temperature resistant are all passed through in whole air and combustion gas before the burning.Owing to be near ideal air-fuel ratio, so sufficient combustion, carbon monoxide is minimum and the flue gas loss is minimum.Owing to be little flame burning, there is not thermal extremes, so nitrogen oxide is few, environmental protection is good.The metallic fiber combustion can reach 2500kw/m around device combustion intensity height ², can reduce to fire volume greatly around device, combustion barrel and boiler; The power output adjustable range is big, from 25%～100%, is particularly suitable for the automatic adjusting of heating according to need, saves the energy greatly.In addition, metal fiber burner also has heat shock resistance, lower resistance, safety no tempering, durable in use, and the life-span can reach 40 years.The 2nd, the burner exhanst gas outlet is provided with the flue gas cyclone, improves the efficient of flue gas and water smoke exchange heat.The 3rd, before exhaust opening, establish a centrifugal moisture trap, drop to the escape of water smoke loss minimum.The 4th, nozzle component is established two-layer, and flue gas is fully cooled off, and reduces the flue gas heat loss to greatest extent.The combination of above advantage can make boiler efficiency reach more than 98%.
