Description

The small-sized heating boiler of Far-infrared Heating formula

The small-sized heating boiler of a kind of Far-infrared Heating formula belongs to civil boiler.

At present, the resident of counties and cities' level, the heating of 80% usefulness coal, general 50-60m at home ²During a heating with coal about 2 tons, timber will be used 2 hackeries, needs cost bigger, adds and buys coal, buys bavin, carries coal, falls manual labors such as ash, splitting material, and contaminated environment.And from the oil burner of external import, the price height, general resident is with rising, and this oil burner promptly consumes oil, consumes electricly again, expends nearly six to ten times expense with general heating mode more.

The purpose of this utility model is to overcome the deficiency that above-mentioned prior art exists, providing a kind of is thermal source with the far infrared vaporization oil stove, with gasoline, kerosene, light diesel fuel is fuel, burn heating boiler by vaporization oil stove, obtain the required hot water of family and reach the purpose of warming through radiator heat-dissipation, and make it safe and reliable, easy to use, expense is low.

The utility model is realized with following technical scheme: comprise the body of heater of being with water jacket, furnace bottom is provided with heating source, furnace body wall is provided with water inlet, delivery port and tail gas outlet, it is by the far infrared vertical fire tube combustion chamber that is made of far infrared vertical fire tube and two ends end plate is installed in the body of heater cavity of resorption, far infrared vertical fire tube combustion chamber is provided with the agglomerating furnace chamber thermal resistance wire inserts in back that stretches, cavity top is provided with the choked flow heater, the choked flow heater by up and down two less than inboard wall of furnace body and be down that the sheet metal of curved arc degree forms a cavity after the outer rim welding, be welded with water inlet on the curved arc degree face down, the other end of water inlet is welded on the inboard wall of furnace body, the choked flow heater is welded with delivery port near on the furnace roof face with its water inlet staggered place, and the upper end of delivery port and the inboard wall of furnace body of furnace roof weld together formation.

Operation principle: be placed on after the far infrared vaporization oil stove is lighted under the stove in the heat source case, form a space between vertical fire tube and the two end plates thereof between inboard wall of furnace body and the body of heater, inject cold water by cold water inlet to this space, cold water is heated the back rapidly toward the circulation of boiler top, entering the choked flow heater by choked flow heater water inlet heats again, heated hot water is continued to inject heating system toward the circulation of boiler top through hot water outlet by choked flow heater delivery port again.At the bottom of the far infrared vaporization oil stove heating furnace, flame passes from vertical fire tube, first heating annotates the cold water in the stove, the flame that passes vertical fire tube enters in the furnace chamber between combustion chamber and the choked flow heater, filled the resistance wire that the stretching of some is opened in the furnace chamber, added the thermal resistance wire inserts with heat energy, the effect of installing the thermal resistance wire inserts in the furnace chamber additional is: 1, pass the heat energy that comes because the drag effect of thermal resistance wire from vertical fire tube, slow down by the tail gas outlet and discharge, furnace temperature is further raise.2, do not have clean-burning oil molecule to burn away in the vaporization oil stove, improve fuel availability.3, heat energy moves to choked flow heater outer rim from the centre along following curved arc degree under the effect of curved arc degree under the choked flow heater, has formed a vortex, makes the thermal resistance wire inserts rubescent, heats up.The heat energy that passes furnace chamber continues to move upward, and impacts on the choked flow heater, because the following curved arc degree of choked flow heater, prolonged the time of staying of heat energy, formed a gyrate thermal treatment zone, discharged by the delivery port of choked flow heater, entered the circulatory system through the hot water of heating again.Gyrate heat energy is moved upward by tail gas outlet on the heater edge, walks around choked flow heater delivery port and discharges from the tail gas outlet.Whole heating is by the vertical fire tube combustion chamber heating first time, furnace chamber thermal resistance wire inserts residual oil molecule heating for the second time and choked flow heater for the third time heat again, through these three times heating, heat energy utilizes totally substantially, whole courses of work of Here it is the small-sized heating boiler of far infrared.

The beneficial effect that the utility model had: if the small-sized heating boiler of far infrared is a thermal source with the far infrared vaporization oil stove, its fuel consumption can maintain an equal level substantially with coal-fired, if housing quality is good, heat-insulating property is more saved with regard to comparable fire coal by force.Its superiority mainly is: 1, because it is not coal-fired,, thereby reduced airborne flue dust not to exterior space discharging coal smoke, and very valuable to the protection environment.2, saved the manual labor of buying coal, buying bavin, carrying coal, fall ash, chop wood, saved time.3, the indoor smoke contamination that no longer is subjected to makes indoor air more pure and fresh, clean.4, the small-sized heating boiler of far infrared is not only economical, and also has the characteristics of quick heating.When the January outdoor temperature was subzero 28-30 ℃, indoor temperature was at 8-10 ℃, and the some combusting boiler is about one hour, and room temperature can be raised to 15-17 ℃.Therefore, the small-sized heating boiler of far infrared is desirable substitute products that substitute traditional coal-burning boiler, and its market potential can be very big.
