Abstract
The present invention relates to a heat-exchanging furnace, consisting of furnace body, fuel oil atomizing jet, burning flame tube, hot-air spreading tube and water liquid atomizing jet. The air is fed into the furnace body by means of fan, and provided for burning flame tube to make fuel oil fully burn, and the burned hot air is passed through the hot-air spreading tube and fed into the hot-exchanging chamber, where it is come into contact with water liquid sprayed out from the water liquid atomizing jet mounted in the upper portion of the heat-exchanging chamber and directly mixed with the water liquid to make heat exchange. Its thermal efficiency is above 92%, and the smoke density of waste gas discharged from furnace top is less than primary scale of lingemantu smoke chart.
Description
The present invention relates to a kind ofly directly contact and the recuperative furnace that carries out heat exchange with water (or not flammable liquid) with the hot gas after fuel oil (gas) burning.
Adding hot water (or not flammable liquid) with fuel oil (gas) burning, all is to adopt pot, kettle or boiler at present, fire and water is separated by metal covering heat.The height of heat transfer efficiency depends on the heat-transfer area material, heat transfer area and the two factors such as flow velocity on metal covering.Although people adopt optimum material, design best heating surface area, its heat-exchanger rig still seems and costs an arm and a leg huge heaviness, and the thermal efficiency does not still reach desirable degree.
The object of the present invention is to provide and a kind ofly directly contact and device---the fire and water direct heat-exchange boiler that carries out heat exchange with water (or not flammable liquid) with the hot gas after fuel oil (gas) burning.
Recuperative furnace of the present invention by body of heater, fuel spray chew, combustion flame tube, hot gas send tube forth and water liquid atomizer aperture is formed, fuel spray is chewed and is arranged on bottom of furnace body; Combustion flame tube is arranged on the body of heater middle and lower part; Hot gas is sent tube forth and is arranged on the body of heater middle part; Its upper space is a Heat Room; Water liquid atomizer aperture is arranged in Heat Room; Send forth between the tube at combustion flame tube and hot gas and to form fiery chamber by diaphragm plate and Heat Room base plate; On the furnace wall, middle and lower part of body of heater, blast pipe is set; On the furnace wall, middle and upper part of body of heater, water inlet pipe and outlet pipe are set; The body of heater top is an aiutage.
The present invention is imported air in the body of heater by blast pipe by air blast, supply with the enough oxygen of combustion flame tube, make fuel oil fully burning in burner inner liner, the horizontal aperture that the hot gas of burning is sent forth on the tube along the hot gas at body of heater middle part enters Heat Room, because Heat Room top is provided with water liquid atomizer aperture, water liquid sprays from top to bottom, hot gas flows from bottom to top, both reverse movements make it fully contact mixing, thereby heat is absorbed the purpose that reaches heat exchange by water liquid.
The present invention since realized hot gas and water liquid directly contact mixing, heat energy is directly absorbed by water liquid, thereby heat loss is minimum, through prototyping testing, whole furnace thermal efficiency is more than 92%, and black furnace is lighted a fire hot water amount's output of declared working condition, water cleaning after 30 seconds, the waste gas smoke intensity that furnace roof portion aiutage is discharged is less than the Lin Geman one-level, and fume amount is less than 10 milligrams/dried mark M
