Abstract
The utility model provides an ordinary pressure inner loop boiler, it includes water jacket, combustion chamber and exhaust port, the exhaust port is located water jacketed upper portion, and the water jacket includes shell and inner wall, constitutes intermediate layer formula water jacket, and its special character is, the combustion chamber be located water jacketed lower part, be connected with the flue gas pipe in the combustion chamber rear end, the other end of flue gas pipe gets into through water jacketed upper portion side to stretch into the water jacket lower part, have vertical cigarette board and transversely roll over the cigarette board on water jacketed inner wall, the advantage lies in that the combustion chamber is located water jacketed lower part, constitutes an independent adiabatic combustion space, makes the combustible gas and the fixed carbon of fuel fully burn under higher temperature, the flue gas pipe stretches into the water jacket lower part to suddenly dilatation, make the granule that carries in the high temperature flue gas with flue gas separation, subside, have vertical cigarette board and transversely roll over the cigarette board on water jacketed inner wall, the high temperature flue gas under of forcing of cigarette board, 90 degree horizontal rotatory risings, 90 degrees rotatory risings of vertical again make the flue gas and the abundant contact that receives the hot side, have improved boiler efficiency.
Description
Technical field
This utility model belongs to a kind of burning heating equipment, particularly to a kind of normal pressure interior circulation hot-water boiler.
Background technology
Hot-water boiler of the prior art has many kinds, wherein most typically water-jacket typ hot-water boiler.Water-jacket typ hot water
Boiler main will be made up of water jacket, fire bars, fire door, stove circle etc..Fuel burns on fire bars, by the water heating in water jacket.And, stove
Thorax is arranged in water jacket, fuel directly burning in water jacket, fuel and water-cooling wall directly contact, and tube wall dust is serious, affects pot
The normal operation of stove, meanwhile, fuel nor burn completely, heat loss is big, high energy consumption, and fire box temperature is low, comburant be heated
The surface radiation coefficient of heat transfer is little.When pyrotechnics and heating surface heat convection, the laminar boundary layer heat of the flue gas formation that wall-cooling surface is detained
Resistance is big, and the coefficient of heat transfer is little, and available energy lost is big, and the heating surface area of stove is little, and the thermal efficiency is low, and heat-transfer effect is undesirable, and uncomfortable
Close and burn low calorie fuels, operating cost height, the poisonous and harmful substances in flue gas and co2, dust content high, air pollution is tight
Weight.
Content of the invention
The purpose of this utility model is to overcome the shortcomings of that prior art exists, and provides that a kind of burning condition is good, fire box temperature
The high normal pressure interior circulation hot-water boiler of height, energy-conserving and environment-protective, the thermal efficiency.
This utility model includes water jacket, combustor and exhaust opening, exhaust opening be located at water jacket top, water jacket include shell and
Inwall, constitutes sandwich-type water jacket, it is characterized in that, described combustor is located at the bottom of water jacket, connects in combustor rear end
There is a smoke tube, the other end of the smoke tube upper side through water jacket enters, and extend into water jacket bottom, in the inwall of water jacket
On have longitudinal smoke bending plate and horizontal smoke bending plate.
Described longitudinal smoke bending plate and horizontal smoke bending plate are arranged in pairs, and longitudinal smoke bending plate and horizontal smoke bending plate alternate up and down
Setting.
Overcoat is additionally provided with smoke tube, constitutes air-water heat exchanger.
Also has observation port in the side of water jacket, in order to observe the content of particulate material in inner flue gas of the stove.
The utility model has the advantage of:
1st, combustor is located at the bottom of water jacket, constitutes an independent adiabatic combustion space, burning condition is good, fire box temperature
Height, makes the fuel gas of fuel and fixed carbon fully burn at a higher temperature, greatly reduces the consumption of the energy.
2nd, smoke tube extend into water jacket bottom, and unexpected dilatation, so that the granule carrying in high-temperature flue gas is separated with flue gas,
Sedimentation, contributes to reducing the solid matter in flue gas, reduces the pollution to air.
The 3rd, longitudinal smoke bending plate and horizontal smoke bending plate, high-temperature flue gas rotation under the forcing of smoke bending plate are had on the inwall of water jacket
Rise, increased being fully contacted of flue gas and heating surface, improve boiler efficiency.
4th, on smoke tube, setting constitutes the overcoat of air-water heat exchanger, fully absorbs the heat energy in flue gas, carries further
The thermal efficiency of high boiler.
Brief description
Fig. 1 is structural representation of the present utility model；
Fig. 2 is a a sectional view of Fig. 1.
Specific embodiment
As shown in drawings, this utility model includes water jacket, combustor 10 and exhaust opening 1, and exhaust opening 1 is located at the upper of water jacket
Portion, water jacket includes shell 2 and inwall 3, constitutes sandwich-type water jacket；Described combustor 10 is located at bottom, water jacket and the combustion of water jacket
Burn and separated with base plate 9 between room 10, constitute an independent adiabatic combustion space, make the fuel gas of fuel and fixed carbon relatively
Fully burn at a temperature of height；There is the mouth 11 that puts a chimney on the stove and make the fire draw in the front end of combustor 10, the effect of the mouth 11 that puts a chimney on the stove and make the fire draw is to combustor 10
Supplement air, dose fuel, observe combustion position；Be connected with smoke tube 7 in combustor 10 rear end, smoke tube 7 another
The upper side through water jacket for the end enters, and extend into water jacket bottom, and flue gas is imported water jacket from combustor 10；In water jacket
Longitudinal smoke bending plate 4 and horizontal smoke bending plate 6 are had on wall 3, described longitudinal smoke bending plate 4 and horizontal smoke bending plate 6 are arranged in pairs, that is, longitudinally
A pair of smoke bending plate 4 two, setting in one plane, horizontal smoke bending plate 6 be also two a pair, setting in one plane, and
Longitudinal smoke bending plate 4 and the alternate setting about 6 of horizontal smoke bending plate, that is, a pair longitudinal smoke bending plate 4 of setting, upper in longitudinal smoke bending plate 4
Face arranges a pair horizontal smoke bending plate 6, then, arranges longitudinal smoke bending plate 4 again, with such order above horizontal smoke bending plate 6
If setting dried layer smoke bending plate, increase the contact with heating surface for the flue gas, and force flue gas rotation to rise；Smoke tube 7 also sets
It is equipped with overcoat 15, constitutes air-water heat exchanger, absorb the heat energy in flue gas further, improve the thermal efficiency of boiler；Side in water jacket
Face also has observation port 5, in order to observe the content of particulate material in inner flue gas of the stove；There is one outlet 14 above base plate 9
With a deashing pipe 8, several through holes are arranged at the bottom of deashing pipe 8, periodically to water filling in deashing pipe 8, you can will fall on base plate 9
