Abstract

The utility model relates to a light weight type quick heating boiler furnace which comprises four parts which are a furnace body, a preheater, an air blower, and a chimney, wherein air is sent into the preheater through the air blower, the preheater preheats the air sent inside through the air blower by using the heat of waste gas which is discharged, preheated air enters into a combustion chamber through an air heating passageway, fuel oil ejected from a oil ejecting pipe is lighted by a fire maker and then the fuel oil combusts, and therefore water in intestine like tubes can be heated. Because four layers of intestine like tubes are orderly connected in the furnace body, the light weight type quick heating boiler furnace is characterized by omnibearing cyclic heating property, full utilization of heat, guaranteed out-coming water temperature, and improved utilization efficiency of fuel oil in the combustion chamber.

Description

Light-duty rapid heating boiler

Technical field

The utility model relates to a kind of rapid-heating device, is specifically related to the boiler of a kind of Fast Heating and heat exchange.

Background technology

General heat-exchange system heat exchange area is little, and the burner heating is slow, and heat exchange efficiency is low, and the waste gas of discharging is taken away a lot of heats, causes very large energy waste.

Summary of the invention

The utility model provides a kind of light-duty rapid heating boiler, the boiler internal water route adopts four layers of intestinal tube that spirals to connect and compose successively, increase heating surface (area) (HS, make that heating is faster, efficient is higher, because each layer intestinal tube is different service life, simultaneously for reducing cost and intestinal tube technological forming, so adopt isolating construction between four layers of intestinal tube, the use joint connects, and is convenient to independent replacing.Preheater is recycled the waste-gas heat of discharging, and the efficiency of heating surface can reach more than 90%, has reduced the fuel oil use cost, plays the effect of energy-saving and emission-reduction, protection of the environment.

The specific embodiment

Operation principle: embodiment of the present utility model is described below in conjunction with accompanying drawing 1 to Fig. 6.

This light-duty rapid heating boiler integral body is made by stainless steel material, comprises body of heater 1, preheater 2, air blast 3 and chimney 4; Body of heater 1 comprises shell 14, is arranged on the air heat passage 11 on shell 14 madial walls, and air heat passage 11 connects preheater 2 and combustion chamber 13.Be close to the intestinal tube group 12 that air heat passage 11 arranges, be arranged on the combustion chamber 13 in the intestinal tube inner ring, be arranged on the furnace chamber 15 at 13 tops, combustion chamber, be arranged on fire maker 17 and the spray bar 16 of furnace chamber 15 inside.

Cold air 51 is sent into preheater 2 by air blast 3, the preheater 2 inner grid channels that adopt, and cold air 51 passes through from different grid channels with flue gas 52.Enter air heat passage 11 from preheater 2, enter again combustion chamber 13.Be provided with fire maker 17 and spray bar 16 by external control system control in the furnace chamber 15, after the fuel oil of spray bar 16 spray feeds was lighted by

fire maker

17,13 internal combustion produced flame 18 and flue gas 52 in the combustion chamber.

Water flows into intestinal tube group 12 after the water filling port injection of intestinal tube group 12.The water of flame 18 in the 13 pairs of intestinal tube groups 12 in combustion chamber that burning produces heats; Intestinal tube group 12 is divided into four layers, and current are introduced into outer intestinal tube, absorbs the heat of combustion chamber 13 radiation and the heat of flue gas 52, successively inwardly flow again and successively heat absorption, be heated rear outflow boiler to the internal layer intestinal tube high-temperature region near the combustion chamber at last, can take full advantage of heat, improve leaving water temperature.

Because intestinal tube 12 is close to air heat passage 11, the heat that intestinal tube group 12 is distributed can add the air in the hot air passage 11 again, and the utilization ratio of combustion chamber 13 intermediate fuel oils is improved simultaneously.Flue gas 52 enters preheater 2, and the cold air 51 that air blast 3 is sent into carries out preheating, discharges from chimney 4 at last.
