Abstract
The utility model belongs to a boiler, which mainly relates to an atmospheric hot-water boiler and comprises a boiler body and a boiler chamber, a heat collecting box and a flue which are arranged in the boiler body. The utility model is characterized in that the upper part of the boiler chamber is provided with a coal feeding port, the lower part of the boiler chamber is provided with a slag removing port, the middle-upper part inside the boiler chamber is provided with a fire grate, the upper part of which is provided with a preheating chamber and the lower part of which is provided with a burning-out chamber, and the side face of the preheating chamber is provided with a burner interface. The utility model has the characteristics of high heat efficiency, low smoke discharge, simple operation, easy control, strong adaptability to fuel, etc., and fully accords with the requirements of environmental protection.
Description
The utility model belongs to boiler, relates generally to normal-pressure hot-water boiler.
The boiler of prior art, no matter be horizontal boiler or vertical boiler, a kind of fuel all can only burn separately, i.e. fire coal, fuel oil or combustion gas, can't accomplish exchange use coal-fired on a boiler, oily, three kinds of fuel of gas, fuel tolerance is poor, brings inconvenience to the user, and soot emissions are higher, pollute more serious.
The purpose of this utility model provides a kind of fire coal, oil, gas normal-pressure hot-water boiler that adapts to pluralities of fuel.
The utility model comprises burner hearth, heat-collecting box and the chimney in body of heater and the body of heater, it is characterized in that upper furnace is provided with coal filling hole, and the bottom is provided with removes cinder notch, the middle and upper part is provided with fire grate in the burner hearth, fire grate top is preheating chamber, and the bottom is the combustion clean room, and the preheating chamber side is provided with the burner interface.
In the body of heater on burner hearth of the present utility model top dust cleaning case is set.The waste-heated water-tank is set around the chimney of upper of furnace body.Fire grate undulate in burner hearth is arranged.
The utility model compared with prior art has:
1, thermal efficiency height, soot emissions are low.When coal-fired, the thermal efficiency can reach more than 75%, dust exhausting concentration＜100mg/Nm
3, lingemann blackness＜0.5 grade; When fuel oil, gas, the thermal efficiency can reach more than 88%, dust exhausting concentration＜3mg/Nm
3, lingemann blackness is a zero level.
2, easy and simple to handle, be easy to grasp.Because in body of heater, set up preheating chamber, so can once add the coal of q.s when coal-fired, reduces frequent coal and operate, alleviated labour intensity and soot emissions greatly; When fuel oil, combustion gas, can realize fully automatic operation, operate easier.
3, fuel tolerance is extremely strong, compliance with environmental protection requirements.This The Application of Technology, can make normal-pressure hot-water boiler fuel accommodation expand existing common fuel to, the user can be according to various places energy scenario and different environmental requirements, select fuel such as bituminous coal, anthracite, moulded coal, heavy oil, residual oil, diesel oil, natural gas, high heating value gas for use and need not big transformation or change whole boiler, economical, flexibly, meet the requirement of environmental protection, the energy.
The utility model is described in further detail below in conjunction with accompanying drawing;
Accompanying drawing is the structural representation of the utility model embodiment;
Among the figure, when fire coal, add coal to precombustion chamber 2, through preheating, volatilization, pre-burning several stages, all combustion is clean in precombustion chamber for volatile matter in the coal and inflammable branch, the coal of process pre-burning falls into combustion clean room 1 by undaform fire grate 6 and burns away, and burning completely, lime-ash can remove the cinder notch discharge from the bottom.Flue gas is by heat-collecting box 3 and dust cleaning case 4 further heat release dedustings, at last by chimney 8 emptyings, owing to waste-heated water-tank 5 be arranged on chimney 8 around, so waste heat can further be utilized.When fuel oil or combustion gas, coal filling hole and fire grate are sealed with refractory material, burner interface 7 is loaded onto burner, can realize fuel oil or combustion gas.Like this, realized on same normal-pressure hot-water boiler, realize that the exchange of pluralities of fuel is used, and boiler body need not to do big transformation, change.
Claims (4)
1, a kind of fire coal, oil, gas normal-pressure hot-water boiler, comprise burner hearth, heat-collecting box and chimney in body of heater and the body of heater, it is characterized in that upper furnace is provided with coal filling hole, the bottom is provided with removes cinder notch, the middle and upper part is provided with fire grate in the burner hearth, fire grate top is preheating chamber, and the bottom is the combustion clean room, and the preheating chamber side is provided with the burner interface.
2, fire coal according to claim 1, oil, gas normal-pressure hot-water boiler is characterized in that in the body of heater on burner hearth top dust cleaning case being set.
3, fire coal according to claim 1, oil, gas normal-pressure hot-water boiler is characterized in that the chimney of upper of furnace body is provided with the waste-heated water-tank on every side.
