The heating methods of twice combustions and multiple fumings meet the feature of combustion and heat release of coal, and the utility model has the advantages of sufficient combustion, little heat loss, high efficiency, no leakage of the flue gas, no dust or color, cleaning and environmental protection, saving coal 40-50% compared with the prior art.

Description

Second-time burning smokeless and dust free efficient energy-saving furnace

Technical field the utility model belongs to a kind of life to be used or production usefulness, particularly the second-time burning formula smokeless and dust free efficient energy-saving furnace of bean product manufacturer use.

Background technology people know, in doing the process of bean curd, need a large amount of boiling water or hot water, and the existing way that boils water is to burn bavins or burning coal with several mouthfuls big iron pans, has plenty of with steam boiler and burns steam, and then remove to heat cold water with steam and become hot water.With big iron pan manufacture hot water's way is for thousands of years traditional method, simple to operate, everybody can, problem is that this way will produce volume of smoke, contaminated air, hinder ecology and environmental protection, next is the flame time of staying weak point that imitation frosted glass forms in the chamber of a kitchen range, has little time heat is passed to a pot body, and oxygen supply is insufficient, incomplete combustion, the heat utilization efficiency of fuel is low.The way of modern burning boiler; owing to increased thermal interface; the utilization rate of fuel improves; but oxygen supply is unreasonable; the problem of incomplete combustion still exists, and boiler is all bigger to the consumption of coal, and the flue dust that is produced is a lot; to environmental protection requirement more and more stricter today, the use of boiler is very limited.In addition, remove to produce steam, form secondary energy sources with boiler, are add hot water long excessively with secondary energy sources again, link is many, and the loss of heat is big, waste is many, and last production cost is often taller than traditional cauldron method of heating up water, and is not generally adopted by the numerous producers.Simultaneously, boiler still is a kind of explosive hazardous equipment, and its operation is had relatively high expectations, and there are strict requirements to this in country, and the non-general common people can arbitrarily use.

The summary of the invention the purpose of this utility model is to propose abundant, complete, the hot second-time burning formula smokeless and dust free efficient energy-saving furnace high, energy-conservation, with low cost, pollution-free, safe in utilization, processing ease of imitating that burns of a kind of oxygen supply, to overcome the deficiencies in the prior art.

This second-time burning smokeless and dust free efficient energy-saving furnace that the utility model proposes, it has shaft, fire bars, burner hearth, it is characterized in that burner hearth is in shaft, separate space is arranged between the two, separate space communicates with recirculated water turnover pipe, and burner hearth bottom has fire bars, and fire bars communicates with ash collection slot, furnace chamber is communicated with the shaft gas pipe for second-time burning outward, the coal filling hole of past burner hearth refuelling is housed on the shaft and gives an air feed pipe of burner hearth oxygen supply.

Burner hearth can be separated into a plurality of combustion chambers, there is coal filling hole each combustion chamber, and coal flap switch is arranged.

Between a plurality of combustion chambers separate space is arranged.

Upper furnace is the gas purification chamber, and purifying the bottom, chamber has filter screen.

The air feed point of an air feed pipe a side of fire bars, below or two sides up and down.

The indoor burner of gas pipe and second-time burning is communicated with, and is connected to secondary air feed pipe, and the top of burner is water bath or other heating container that is connected with circulating water outlet pipe.

The utility model adopts burning for the first time to heat separate space recirculated water in advance, burn for the second time design of the further heat cycles water of coal gas, fuel combustion is abundant, and the release conduction of heat absorbs does not stay the dead angle, whole process is all passed to recirculated water to heat, the thermal efficiency is high, and twice combustion all carries out in the combustion chamber of sealing, and flue gas does not have and leaks outside, and the filtration of process tar and dust, the chimney tail gas discharged is dustless colourless, and very cleaning is not polluted environment.The used blower power of the utility model is very little, wants little more than one times, easy to operate than tradition burning cauldron and steam boiler air blast, just added once new coal in average 7-12 hour, management cost is very low, and than existing hot water method and equipment, total coal saving rate is at 40-50%.Fuel collection Jiao fuel whether smoothly no matter.
