Abstract

The utility model discloses a hot-plate type pressureless hot-water boiler which has the advantages of high thermal inefficiency, wide fuel application range, large heat exchange area, easy soot removal, low steel consumption, etc. The utility model is characterized in that heated components are a plurality of hot plate components parallel arranged, a fire grate is a water-cooling fire grate, and a gas passage is a three-back stroke S-shaped flow passage. The advanced technology of a hot plate is applied into a hot water boiler by the utility model, the interval of a flue is large, and wood dust, branches, straws, can be combusted. The hot-plate type pressureless hot-water boiler is low in cost and convenient in maintenance.

Description

The hot plate type unpressurized hot water boiler

The utility model relates to a kind of solid fuel fired boiler.A kind of specifically application hotplate technology, a kind of small-sized unpressurized hot water boiler of design.

General hot-water boiler, as Chinese patent CN91228678 was disclosed, its main absorber was the metal cabinet that stove water is housed.Realize heat exchange by metal outer wall.This heat exchange method, the thermal efficiency is lower, and it is narrower that flue designs, and rolled steel dosage is big.A kind of hot plate new technology that is widely used in the hot changing device is arranged at present, is heat transferring medium with the solvent of special formulation, and it is fast to have a heat of absorption, the big advantage of thermal content, but being applied in the small-sized water heater of this new technology success.At present at the product of not seeing ripe typing on the market.

The utility model purpose is hotplate technology is applied to small-sized unpressurized hot water boiler.Disclose a kind of heat and imitate height, be suitable for the wide new design of hot plate type unpressurized hot water boiler of fuel range.

Its composition of the utility model comprises: the side wall that is formed by inside and outside double wall; The upper furnace door in body of heater front, the side of formation; Middle fire door; Lower furnace door; Separating the body of heater inner chamber is the slag district, combustion zone, the fire grate in flue gas district and the assembly that is heated.It is characterized in that: the assembly that is heated is the horizontal water tank that is communicated with water-cooling wall by two ends, and the part of plate body extend into the hot plate assembly that a plurality of hot plates that are arranged in parallel in the horizontal water tank are formed.Fire grate is that intracavity section is down trapezoidal water-cooled grate, and its front and back end is communicated with water return outlet and side wall through front and back charge for remittance cover.Hearth wall is to build the heat insulation wall that refractory insulating layer is arranged around the combustion zone.The exhaust gases passes in flue gas district is: three backhaul S shape runners, be by one group at the body of heater top, two groups in the flue gas district up and down spaced apart hot plate assembly form.

The utility model adopts the ripe board component of the many groups absorber of deciding, and its heat is imitated high.Exhaust gases passes is designed to three spacious backhaul S shape runners, and the heat in the flue gas is absorbed repeatedly by hot plate, the fume emission smoothness, and be combined with upper furnace door, be convenient to remove the flue dust in the flue, the utility model is made the attached heating surface that helps by water-cooling wall and water-cooled grate, can make full use of waste heat.And burner hearth cavity is higher, is fit to the burning pluralities of fuel.The plant straw bigger as some volumes, that calorific value is less, and branch etc.

Accompanying drawing 1 is the utility model embodiment front half sectional view.

Accompanying drawing 2 is the sectional view of Fig. 1.

As can be seen from Figure 1, by upper furnace door 3, middle fire door 2, the front of lower furnace door 1 formation side's body of heater.Upper furnace door 3 is a shoot door, and middle fire door 2 is thrown in door for fuel, and lower furnace door 1 is the scarfing cinder fire door.The front and back end of water-cooled grate 8 is communicated with water-cooling wall 4 through water jacket 913.Burner hearth 7 inwalls post refractory insulating layer, and main heated body is the hot plate assembly, and the hot plate module body is a horizontal water tank 5, and a plurality of parallel hot plates 6, its first half stretch in the stove water in the horizontal water tank 5, and the bottom extend into flue gas district or combustion zone.By the media implementation heat exchange in the hot plate 6.Stove water is heated up rapidly.Stove water from water return outlet 10 through after water jacket 9 make fire grate 8 and water-cooling wall 4, preceding charge for remittance cover 13 and horizontal water tank 5 are full of stove water.Rise gradually after stove water is heated and flow, flow out body of heater through managing 12.Fuel is rendered on the water-cooled grate 8, and burned flame is baked hot plate 6, and flue gas is rolled over 180 ° backward and entered the middle level flue, carry out heat exchange with second group of hot plate again, be folded to 180 ° again and enter the upper strata flue and contact, enter chimney, form three backhaul S shape runners therefrom through outlet flue 11 with the 3rd group of hot plate.

The utility model hot plate assembly can increase and decrease according to the body of heater parameter, can not be considered as outside the utility model right because of the variation of hot plate component count for this reason.
