Description

A kind of energy-efficient heating stove

Technical field

The utility model relates to a kind of heating stove, particularly makes the heating stove of fuel with coal.

Background technology

The coal heating furnace structure that use existing family expenses or work or management place, its combustion system generally is, coal directly is invested in the combustion chamber, and air enters the combustion chamber from the bottom, combustion chamber and makes coal combustion, and the flue dust that burning produces is directly discharged from the flue on top, combustion chamber.The deficiency of this furnace binding is, the low temperature oven coal often burns insufficient, and the coal waste is big, and high temperature furnace high temperature can not get reasonable use, high temperature often occurs and burns the slag phenomenon, and have the flue dust of a large amount of heats, can cause damage by direct discharging.

Summary of the invention

The purpose of this utility model provides that a kind of can to overcome existing heating stove coal combustion insufficient, and high temperature burns slag, and the flue heat big deficiency that runs off, coal is fully burnt and not high temperature burn slag, the energy-efficient heating stove that calory burning is fully utilized.

The utility model is achieved in that this heating stove is made up of combustion furnace and cigarette stove, combustion furnace is provided with stove outer covering, be provided with the chamber of coalingging in the stove outer covering, constitute the combustion chamber by side space under coaling the chamber surrounding space and the chamber of coalingging, in the combustion chamber, be provided with and curl up in the outdoor several water pipes side by side that enclose of coalingging, it is coil, the coil outer periphery is equipped with flame retardant coating or water tank, between flame retardant coating or water tank and stove outer covering, be provided with heat insulation layer, below the chamber lower port of coalingging, be provided with funneling round platform, be distributed with air inlet on the shape wall of round platform slope, the round platform bottom is provided with the stove tooth, the stove tooth is installed on the stove tooth rack, stove tooth rack is connected with the stove tooth rack dish, constitutes grey chamber by stove tooth rack dish to the surrounding space bottom the stove outer covering, is provided with water pipe in the cigarette stove outer covering, pipe outer wall is provided with blade, and this blade constitutes spiral the connection along length of pipe direction and water wall.By adopting above structure, coal is packed into when coalingging the chamber, because of the chamber lower port of coalingging to being open spaces between the funneling round platform, so the mountain shape that can form some from chamber lower port to the round platform bottom oven between cog of coalingging is piled up the coal seam.When outside coal is being coaling the chamber lower port, beginning to burn, the chamber upper port of will coalingging capping in addition, this moment, the chamber of coalingging was similar to coke oven, its top makes coal by destructive distillation because of blowing air not, has formed the destructive distillation coal with uniform temperature and the combustible gas and the solids of generation and has reduced to the combustion process that lower end, the chamber exterior combustion chamber of coalingging burns slowly.When blasting enough strong wind-force from the stove tooth when making burning such as coking coal, high heat that produces and flue gas then can be radial along the funnel-form space that round platform constitutes and scatter and rise, avoided high temperature coalescent, simultaneously, the wind that enters from round platform slope shape wall air inlet can further make smoke combustion and enter combustion chamber on every side, the chamber of coalingging, because the existence of coal-fired chamber coil, high temperature fully and directly acts on coil, make heat energy be converted to high-temperature-hot-water rapidly, constantly output realizes heat supply to environment from coil.When the burnt gas that still has certain heat enters the cigarette stove, because the effect of blade in the cigarette stove, the blade of thermal current on rotation fully contacts, make blade effectively most heats are imported into the blade water pipe connecting in, the low-temperature water heating of generation is admitted to the coil water inlet.

The utility model has the advantages that the coal burning utilization is abundant, heat loss is few, heat energy utilization rate height, efficient energy-saving.

Below in conjunction with accompanying drawing the utility model is further specified.
