Abstract

The utility model discloses an energy-saving heating boiler, which comprises a furnace body; wherein, an upper combustion chamber and a lower combustion chamber are arranged inside the furnace body and the fuel is made combust fully; the hot fuel gas exhausted by the lower combustion chamber goes through the two-pass heat exchanger arranged outside the furnace body, exchanges heat with the water fully, goes through the three-pass heat exchanger section; the residual heat exchanges with the water fully again and is exhausted. The utility model is characterized in full heat exchange and settling a majority of dust of the flue gas in the furnace body because of the long process of heat exchange. The utility model has the advantages of high thermal efficiency and good feature of environment protection.

Description

A kind of energy-saving heating boiler

Background technology

Novel a kind of civil boiler, the particularly a kind of energy-saving heating boiler of relating to of this reality.In existing small-sized civil heating boiler technology field, adopt the mode heat exchange that adds water jacket in the body of heater or increase some fire grates more.Because the water jacket heat exchange area is little, the fire grate that is in the body of heater is shorter, so the water of heat medium will have the heat of considerable part to drain with flue gas with the heat exchange between the hot flue gas and insufficient like this, the result wastes energy, and has the compound of atmosphere pollution and flue dust to enter in the atmosphere again.

Novel purpose

The purpose of this utility model is to provide a kind of small-sized domestic energy-saving type heating boiler, and it has thermal efficiency height, the advantage of energy-conservation environmental protection again.

Technical scheme

The technical solution of the utility model is such: on a columniform body of heater, the horizontal tubulation of the logical flue gas of group is arranged at its top, and the tubulation left end leads to smoke box, and right-hand member leads to the two return heat exchanger; Its underpart is respectively upper combustion chamber, lower combustion chamber and cinder chamber; Between upper combustion chamber and lower combustion chamber two Room, separate by fire grate; Be provided with two quadruple pass heat exchangers outside body of heater, its top is linked to each other with body of heater respectively by flue by trunnion, bottom.The outer wall of lower combustion chamber is an intercalated water sleeve, and the fire grate two ends between two Room all communicate with water jacket; In the bottom of lower combustion chamber is the cinder chamber of grate and band cleanout door.Be provided with the two return heat exchanger in the outside of body of heater, its top links to each other with body of heater three backhaul tubulations by connecting trunnion, and the bottom is communicated with lower combustion chamber by flue, and top and side have the connection pipe logical with the water in the body of heater respectively.

Outstanding advantage of the present utility model is the sufficient combustion of fuel, and secondly thermal efficiency height, fuel savings are that flue gas flow is long, and fully sedimentation dust reduces the pollution to environment.

Description of drawings

Below in conjunction with accompanying drawing the utility model is elaborated: Fig. 1 be the utility model along center line B-B face cutaway view, Fig. 2 is front view of the present utility model and partial sectional view, Fig. 3 is a vertical view of the present utility model, Fig. 4 is Figure 1A-A revolved sectional view.

Among the figure just like lower member: 1 body of heater; 2, three backhauls; 3, temperature gauge pipe; 4, hot water outlet; 5,15 pipes; 6, two return heat exchanger; 7, ash disposal mouth; 8, cinder chamber; 9, base; 10, fire grate; 11, fire grate; 12, upper combustion chamber; 13, smoke box; 14, exhaust smoke hole; 16, pressure gauge stand; 17, trunnion; 18, return pipe; 19, clean-out opening; 20,21 fire doors; 22, cleanout door; 23, blow-off pipe; 24, flue; 25, lower combustion chamber; 26, water jacket; 27, tubulation.

Embodiment

Provide an embodiment as shown in Figure 1 below: the fuel in the upper combustion chamber 12 burns within it, some uncombusted fuel burning once more in lower combustion chamber 25 simultaneously, behind twice combustion, the fuel remaining lime-ash that burnouted substantially drops in the cinder chamber 8, can remove from cleanout door 22.In upper combustion chamber 12, the heat that produces in the lower combustion chamber 25 is at first given the heating of the water in chuck 26 and the fire grate 11; The red-hot flue gas that produces in the combustion process in flue 24 flows to two return heat exchanger 6, is given the water that is in its chuck and comb heating more again; The waste heat flue gas enters under fan action in the tubulation 27 then, heats being in tubulation 27 water on every side at last, and flue gas is discharged through smoke box 13, exhaust smoke hole 14.Water is to enter through return pipe 18, flows out from hot water outlet 4, finishes a circulation heating process.
