Description
[technical field]
The present invention relates to gas furnace, relate in particular to gas safe prewarming circulating system in the gas furnace.
[background technology]
For curbing environmental pollution, force without the coal furnace of qualified discharge and to have been stopped using, be that the stove of fuel is widely used with the natural gas of cleaning, oil gas etc.Combustion gas and preheating of air temperature are high more in this class stove, and combustion gas utilizes the diffusion reaction of combustion-supporting combustion air fast more, and mixability is abundant more, and it is complete more to burn, and be more little by the cooling loss that cold combustion gas, cold air produce, thereby make the temperature of combustion product high more.
Present stove all adopts and concentrate preheating in flue, and the mode of disperseing to be transported to each burner then wherein also needs electronic air inducing and air blast.Adopt the preheat temperature of this mode not high, air preheating temperature rests between 300-700 ℃; Hot-air cooling loss unavoidably needs to use more combustion gas keep high temperature in the course of conveying; Air inducing, air blast energy consumption are big.For addressing the above problem, the applicant has also applied for a kind of gas-saving type energy-saving-type gas furnace simultaneously, to the preheating of combustion air overlength, is preheating to maximum temperature and uses immediately, has reduced heat loss.
Simultaneously, all the combustion gas of adopting normal temperature in the present stove, some combustion gas districts are cold-producing medium sky combustion mixing to combustion gas, raising to the combustion product temperature all seriously influences, make fuel gas buring abundant inadequately, efficiency of combustion is low, finishes certain need of work of firing and uses more combustion gas, wastes energy.
[summary of the invention]
Purpose of the present invention solves the problems of the prior art exactly, proposes a kind of gas safe prewarming circulating system, can make the more abundant burning of combustion gas, and the efficiency of combustion height is finished certain need of work of firing and used still less combustion gas, saves the energy.
For achieving the above object, the present invention proposes a kind of gas safe prewarming circulating system, comprise burner, Gas Pipe, one end of described Gas Pipe is provided with burner, also comprise boiling water carrier pipe, preheating water pipe, return pipe, cistern, heat-exchanger pump, preheater and hot-water line, described Gas Pipe and boiling water carrier pipe are set up in parallel in the preheating water pipe, described return pipe one end is arranged on the preheating water pipe, the other end is connected to cistern, described cistern is connected to preheater by heat-exchanger pump, and preheater is connected to the boiling water carrier pipe by hot-water line.
As preferably, also comprise circulating-water valve, described circulating-water valve is arranged between cistern and the heat-exchanger pump.
As preferably, also comprise water valve from the beginning, described water valve from the beginning is arranged on the front end of heat-exchanger pump.
Beneficial effect of the present invention: the present invention adopts circulating hot water that preheating is carried out in combustion gas outside Gas Pipe, between gas-preheating to 90 ℃-100 ℃, and is preheating to the fuel gas inlet place of every burner, immediately with the hot-air hybrid reaction always.The combustion gas of preheating can more abundant burning, and efficiency of combustion is higher, finishes certain need of work of firing and uses still less combustion gas, has saved the energy.The preheat temperature of control combustion gas far below 465 ℃ the burning-point of combustion gas in ignition range, guarantees the safe and reliable of native system between 90 ℃-100 ℃.
Feature of the present invention and advantage will be elaborated in conjunction with the accompanying drawings by embodiment.
[description of drawings]
The structural representation of a kind of gas safe prewarming circulating system of Fig. 1 the present invention.
[specific embodiment]
As shown in Figure 1, a kind of gas safe prewarming circulating system, comprise burner 1, Gas Pipe 2, one end of described Gas Pipe 2 is provided with burner 1, also comprise boiling water carrier pipe 3, preheating water pipe 4, return pipe 5, cistern 6, heat-exchanger pump 9, preheater 10 and hot-water line 11, described Gas Pipe 2 and boiling water carrier pipe 3 are set up in parallel in preheating water pipe 4, described return pipe 5 one ends are arranged in the preheating water pipe 4, the other end is connected to cistern 6, described cistern 6 is connected to preheater 10 by heat-exchanger pump 9, and preheater 10 is connected to boiling water carrier pipe 3 by hot-water line 11.Preheater 10 is arranged in the outer discharge flue of gate mouth, utilizes the fume afterheat in the stove that the water in the preheater 10 is carried out preheating.To be used for the preheating of water through the hot flue gas that stove discharges voluntarily, to hot flue gas function at the present and the past reasonable utilization.
In the combustion gas course of conveying, in boiling water carrier pipe 3, feed hot water, hot water enters preheating water pipe 4 heat is delivered in the Gas Pipe 2, make gas-preheating to 90 ℃ about-100 ℃, through overheated conversion, slightly Jiang Wen water flows in the cistern 6 by return pipe 5, by heat-exchanger pump 9 water is pumped in the preheater 10 then, preheater 10 will be delivered to new hot water in the boiling water carrier pipe 3 by hot-water line 11 behind the water preheat again, so repeatedly circulation.
Also comprise circulating-water valve 7, described circulating-water valve 7 is arranged between cistern 6 and the heat-exchanger pump 9.Circulating-water valve 7 can cut off the output of the water in the cistern 6, stops the circulation of hot water.When the preheat temperature of combustion gas is too high, hot water can be disconnected.Also comprise water valve 8 from the beginning, described water valve from the beginning 8 is arranged on the front end of heat-exchanger pump 9, and when needs were changed intrasystem water, water valve 8 was opened from the beginning, and new running water is input in the system.During work, water valve 8 cuts out from the beginning, and intrasystem water circulates repeatedly.
Combustion gas is in ignition range, and burning-point is at 465 ℃, therefore, is feasible to carrying out preheating without the combustion gas that mixes with air.Present embodiment preferably is controlled at the preheat temperature of combustion gas between 90 ℃-100 ℃, can either guarantee the safe and reliable of system, can make the more abundant burning of combustion gas again, significantly improves the efficiency of combustion of combustion gas.Adopt the present invention can save combustion gas about 20% separately.Adopt this present invention to combine and to save combustion gas about 40% with a kind of gas-saving type energy-saving-type gas furnace of the applicant's application.And needed furnace temperature is high more, and the needed temperature retention time of product is long more, and then energy-saving effect is obvious more, and the solar term rate is high more.About 1450 ℃, fire to use in the kiln of corundum refractory brick and can save combustion gas more than 40%.
The foregoing description is to explanation of the present invention, is not limitation of the invention, any scheme after the simple transformation of the present invention is all belonged to protection scope of the present invention.
