Description

Normal pressure multiple-purpose water heating oven body

Technical field

The utility model belongs to moulded coal, anthracite or with coal-fired grate of imflammable gas pluralities of fuels such as natural gas, oil liquefied gas, coal gas, biogas or burner inserts atmospheric hot-water body of heater in the body of heater, be particularly related to a kind of normal pressure multiple-purpose water heating oven body, can be used for multiple uses such as independent heating, bathing and food and drink cooking stove.

Background technology

At present, medium small boiler mostly is the single-fuel type, i.e. gaseous fuel or coal.And function singleness, the thermal efficiency is low, mostly be two return or three backhauls (1 backhaul wherein is a radial pattern), heat generating spot and water layer distance, combustion back gas travel distance is short, causes the thermal efficiency low, the discharge temperature height, mostly between 180-400 ℃, the heat that combustion gas produces can not get comprehensive exchange in stove, makes it that the thermal efficiency is low, volume is big, materials are many.Manufacturing cost height, shortcoming such as weight is big and purposes is single.

Summary of the invention

It is big that the purpose of this utility model provides a kind of heat exchange area, combustion back gas travel distance is long, use pluralities of fuels such as moulded coal, anthracite, oil liquefied gas, natural gas, coal gas, biogas, multi-purpose normal pressure multiple-purpose water heating oven bodies such as dish, bathing, heating can be used for cooking.

The utility model normal pressure multiple-purpose water heating oven body, include the inner furnace of water filling layer, combustion back gas hot switching path, base, water inlet pipe, outlet pipe, shell is characterized in that: body of heater is made up of cylindric inner furnace by the water filling layer, outer furnace, concrete system shell and outer cover suit by the water filling layer from the inside to the outside successively.Interlayer is combustion back gas hot switching path between inner furnace and the outer furnace, and interlayer also is combustion back gas hot switching path between outer furnace and the concrete system shell.End ring shape cross section, gas access is provided with whirlwind sheet after the combustion of the hot switching path of inner furnace and outer furnace upper end.Also be provided with whirlwind sheet on the end ring shape cross section, gas access after the combustion of the hot switching path of outer furnace and concrete system shell lower end.Inner furnace water filling layer bottom is communicated with cold water inlet, and outer furnace water filling layer top is communicated with the hot water outlet pipe.Top and the bottom between inner furnace water filling layer and the outer furnace water filling layer are communicated with by heat pipe and cold conduit respectively.The bottom of concrete system shell also is provided with dust-cleaning hole.

During use, burner or coal-fired grate are inserted in the body of heater, water inlet pipe advances cold water through inner furnace water filling layer, imports outer furnace water filling layer by cold conduit, is communicated with inside and outside courage water filling layer by heat pipe.At this moment, combustion back gas by upper of furnace body through the hot switching path top of interior outer furnace to the bottom, make the air-flow rotation through whirlwind sheet, the hot switching path of air-flow between outer furnace and concrete system shell from the bottom to top, make air-flow quicken rotation through another group whirlwind sheet again, flow out by flue after finishing heat exchange.When cooking food, bell and fire sealing cover are taken off.When heating and bathing, be the shape of banking up a fire, when all banking up a fire, air door shut.

The utility model has the following advantages compared with the prior art:

1, multipurpose.Have the dish of can cooking, again can heating, bathing and hot water is provided.

2, be suitable for pluralities of fuel.Fuel gas such as available moulded coal, anthracite and natural gas, oil liquefied gas, coal gas, biogas.

3, heat is imitated height, energy savings.Heat exchange is carried out on interior outer furnace two sides, and heating surface reaches 2.5-5m ², installed two groups of whirlwind sheets additional in the gas passage of combustion back, make thermal current reach per second 4-8M.

4, volume is little, in light weight, and manufacturing process is simple, and cost is low.
