Technical field

The utility model relates to a kind of heat resource equipment, particularly a kind ofly utilizes biomass fuel to glow to produce heat and be supplied to the combustion pond, ground gone of heating terminal.

Background technology

Need to there is thermal source to the indoor heating that carries out in cold winter, generally adopt traditionally the mode of boiler combustion coal to carry out large-area unified heating, this heating system is comparatively general in city, but in vast rural area and be not suitable for, first builds boiler room, outfit boiler and corollary equipment, laying heat supply pipeline all needs to expend a large amount of expenses and labour, why city can adopt the unified heating of boiler is because just these infrastructure are configured completely at the beginning of city-building, rural area needs to reconstruct on a large scale, and cost is very high.In order to solve heat supply in winter problem, in rural area, some area is used underground fuel pool as heating source now, underground fuel pool is a kind of pond shape structure being positioned under earth's surface, it utilizes the common living beings in rural area as fuel (straw, rice husk, wood chip, branch etc.), in fireless situation, carry out smoulder (this phenomenon be called glow), to reach the object of heat in slow release supply chamber.But traditional underground fuel pool is due to the restriction in its design, only can utilize its upper end face function of environment heat emission towards periphery, cannot realize the circulation of heat transferring medium, and there is carbon monoxide leakage phenomenon in underground fuel pool, there are major safety risks, therefore there is larger limitation.Because its overall structure is arranged on underground, therefore building and operating extremely wastes time and energy simultaneously.

Summary of the invention

The utility model is in order to solve the existing above-mentioned deficiency of prior art, proposes a kind of simple in structurely, designs ingeniously, can replace boiler as heating source, integrated cost is cheap, and heating duration is long, safe and reliable, durable combustion pond, ground.

Technical solution of the present utility model is: a kind of pond of firing on the ground, it is characterized in that: described combustion pond, ground comprises the combustion pond body 1 that is arranged on ground sealing, on combustion pond body 1, be provided with the exhaust chimney 2 being communicated with its inner chamber, the overcoat 3 that the outermost layer of combustion pond body 1 is hard, in overcoat 3, be disposed with heat-insulation layer 4, combustion bay wall body 5 and heat insulation layer (17), top at combustion pond body 1 is provided with accumulation of heat top board layer 6, in accumulation of heat top board layer 6, be provided with coil pipe 7, what communicate with coil pipe 7 is provided with water inlet pipe 8 and outlet pipe 9, one side of combustion pond body 1 offers feed inlet and outlet 10, in the combustion pond body 1 near feed inlet and outlet 10 places, pile up the interlayer 11 having with passage, the inner chamber of combustion pond body 1 is divided into glow chamber 12 and operating cavity 13 two parts by interlayer 11, what be connected with operating cavity 13 is also provided with air inlet 14.

On described exhaust chimney 2 and air inlet 14, be provided with air-door actuator 15.

The top in the described chamber 12 of glowing is provided with cooling fire extinguishing tube 16.

Compared with the existing technology, tool has the following advantages the utility model:

The combustion pond, ground of this kind of version, it is simple in structure, designs ingenious, rationally distributed.It is designing and structural shortcomings and deficiencies for traditional underground fuel pool, design a kind of independent building structure that is positioned near the ground of heating building of glowing that can realize equally, it can make full use of the common biomass resource in rural area as fuel, in saving the energy, can also generate heat for a long time, and heat is flowed in each heating terminal (geothermal pipe line) by heat transferring medium, and because it is arranged on ground and is to be positioned at outdoor independent building, without poisonous gas leakage, safe and reliable.Its operation also facilitates many compared with underground fuel pool.And its manufacture craft is simple, and the thermal efficiency is high, and integrated cost is cheap, long service life.Therefore can say that it has possessed multiple advantage, be particularly suitable for applying in the art, its market prospects are very wide.
