Abstract
The utility model relates to an efficiency of furnace is inside to conduct heat is improved novel burner. Its technical scheme is: vertical kitchen range be the cuboid shape below, and the top of cuboid is equipped with the bulge of funnel shape, and the top of vertical kitchen range is equipped with spherical concave surface, and the upper left corner of vertical kitchen range is equipped with the kitchen range exhaust port, the inside burning section of thick bamboo of having placed of vertical kitchen range, and a burning section of thick bamboo be cylindrical structures including stack shell, sphere steel sheet, air current hole, the shape of stack shell, and the top and the welding of sphere steel sheet of stack shell are in the same place, are equipped with a set of or a set of above air current hole on the sphere steel sheet. The beneficial effects are that: the use of this novel burning section of thick bamboo will make the thermal current transfer mode given first place to by convective heat transfer and change heat transfer into and give first place to, and the transmission of energy is the quartic side of temperature, will improve heat transfer efficiency and fuel utilization efficiency greatly like this, improve the even degree that thermal current density distributes simultaneously, improve the spherical concave surface third degree of depth and receive the calorific intensity to the two -thirds depth extension in.
Description
Technical field
The utility model relates to a kind of Novel combustion device improving burner hearth internal heat transfer efficiency.
Background technology
Energy crisis spread the development that can restrict national economy, traditional vertical cooking stove is based on convection heat transfer' heat-transfer by convection, and mode of heating is single; be heated uneven; Fuel Consumption is large, and heat transfer efficiency is low, and there is the problems such as imperfect combustion, harmful substances from flue gases content is higher, combustion noise is large.
Summary of the invention
The purpose of this utility model is exactly in view of the foregoing defects the prior art has, provides a kind of Novel combustion device improving burner hearth internal heat transfer efficiency.This new combustion cylinder changes traditional heating mode, based on radiant heat transfer, makes full use of smoke heat energy, improves turbulent extent and the heat transfer efficiency of flue gas, increases the uniformity coefficient of spherical concave surface heat flux distribution.
Its technical scheme is: comprise vertical cooking stove, cooking stove exhaust opening, spherical concave surface, combustion barrel, it is rectangular shape below vertical cooking stove, the top of cuboid is provided with funnel shaped protuberance, the top of vertical cooking stove is provided with spherical concave surface, the upper left corner of vertical cooking stove is provided with cooking stove exhaust opening, vertical range interior is placed with combustion barrel, combustion barrel comprises stack shell, sphere steel plate, airflow hole, the shape of stack shell is columnar structured, the top of stack shell is together with sphere Plate Welding, and sphere steel plate is provided with a group or more airflow hole.
Above-mentioned, the inside of combustion barrel is hollow, and combustion barrel covers in above the flame of vertical range interior.
The beneficial effects of the utility model are: the combustion barrel of raising burner hearth internal heat transfer efficiency of the present utility model, and adopt high temperature resistant stainless steel plate to be material of main part, in use procedure, anti-unstability performance is good, and structure is simple, and production procedure is convenient.This new combustion cylinder is by thermal source size expansion, improve the less turbulence that flue gas flows therein, prolong smoke is in the time of staying of range interior, while the spherical concave surface minimum point heat intensity of guarantee, improve the heat flow rate per unit area of spherical concave surface 1/3rd degree of depth to three/bis-depth areas, make full use of the radiant heat energy of high-temperature flue gas, change traditional vertical cooking stove with convection current for main heat transfer type, by overall thermal efficiency raising 30%.
Accompanying drawing explanation
Accompanying drawing 1 is structural representation of the present utility model;
Accompanying drawing 2 is combustion barrel structural representations of the present utility model;
In upper figure: vertical cooking stove 1, cooking stove exhaust opening 2, spherical concave surface 3, combustion barrel 4, stack shell 4.1, sphere steel plate 4.2, airflow hole 4.3.
Detailed description of the invention
1-2 by reference to the accompanying drawings, the utility model will be further described: comprise vertical cooking stove 1, cooking stove exhaust opening 2, spherical concave surface 3, combustion barrel 4, be rectangular shape below vertical cooking stove 1, the top of cuboid is provided with funnel shaped protuberance, the top of vertical cooking stove 1 is provided with spherical concave surface 3, the upper left corner of vertical cooking stove 1 is provided with cooking stove exhaust opening 2, vertical cooking stove 1 inside is placed with combustion barrel 4, combustion barrel 4 comprises stack shell 4.1, sphere steel plate 4.2, airflow hole 4.3, the shape of stack shell 4.1 is columnar structured, top and the sphere steel plate 4.2 of stack shell 4.1 weld together, sphere steel plate 4.2 is provided with a group or more airflow hole 4.3.
Wherein, the inside of combustion barrel 4 is hollow, and combustion barrel 4 covers in above the flame of vertical range interior.
Described stack shell 4.1 is formed by high temperature resistant stainless steel soil weld, top and the sphere steel plate 4.2 of stack shell 4.1 weld together, the airflow hole 4.3 sphere steel plate 4.2 top having some flows for flue gas, combustion barrel size takes into full account the ductility of flame height and width, ensures that flow of flue gas is smooth and easy.During use, cover on above flame by this new combustion cylinder 4, high-temperature flue gas transfers heat to combustion barrel 4, thus generation cubic heat source, carry out heat transmission to spherical concave surface 3, flue gas flows out from the airflow hole 4.3 combustion barrel 4 sphere top, and the cooking stove exhaust opening 2 finally through vertical cooking stove is discharged.
The combustion barrel of raising burner hearth internal heat transfer efficiency of the present utility model, adopt high temperature resistant stainless steel plate to be material of main part, in use procedure, anti-unstability performance is good, and structure is simple, and production procedure is convenient.This new combustion cylinder is by thermal source size expansion, improve the less turbulence that flue gas flows therein, prolong smoke is in the time of staying of range interior, while the spherical concave surface minimum point heat intensity of guarantee, improve the heat flow rate per unit area of spherical concave surface 1/3rd degree of depth to three/bis-depth areas, make full use of the radiant heat energy of high-temperature flue gas, change traditional vertical cooking stove with convection current for main heat transfer type, by overall thermal efficiency raising 30%.
The above is only preferred embodiment of the present utility model, and any those of ordinary skill in the art all may utilize the technical scheme of above-mentioned elaboration to the utility model correct or are revised as equivalent technical scheme.Therefore, any simple modification of carrying out according to the technical solution of the utility model or substitute equivalents, belong to the greatest extent the scope that the utility model is claimed.
