Alcohol-based high-temperature gasifying fire control furnace

Abstract

The invention relates to an alcohol-based high-temperature gasifying fire control furnace which comprises a furnace center, a fire control cover, a fire control ring, and a fire expansion plate, wherein the fire control cover is arranged above the furnace center; the fire control ring is arranged at the outer periphery at the upper part of the fire control cover; the fire expansion plate is arranged above the fire control ring; a first high-temperature gasifying combustion chamber is formed between the furnace center and the fire control cover; a second high-temperature gasifying combustion chamber is formed between the fire control cover and the fire control ring; a third high-temperature gasifying combustion chamber is formed among the fire expansion ring, a pot ring and an iron pot. The furnace has the advantages that the temperature of a main hearth can be improved by 150 to 200 DEG C based on the original temperature; the temperature of the furnace can exceed that of a diesel furnace by 200 DEG C, which overcomes the technical defect that the temperature of a national or international bio-alcohol oil furnace is lower than that of a diesel furnace; heat can be reserved and stored, so as to give full play to the combustion efficiency of fuel.

Description

technical field [0001] The invention belongs to stove burner equipment, in particular to an alcohol-based high-temperature gasification control burner. Background technique [0002] Previously, the invention patent of the alcohol-based high-temperature gasification control furnace (China Patent No. ZL201310644183.6, application date 2013.12.04) was applied by the inventor on December 4, 2013. Although the firepower surpassed that of the fanless gasification furnace 1. There are fan gasification furnaces and diesel furnaces using diesel as fuel, but there are still the following deficiencies and shortcomings: (1) The space of the high-temperature gasification combustion chamber is too large, which is not conducive to energy saving and improvement of firepower. Now the refractory ring is omitted , reducing the space of the high-temperature gasification combustion chamber by about 50%; (2) The ignition hole set in the middle of the fire control cover brings inconvenience to the...

[0002] Previously, the invention patent of the alcohol-based high-temperature gasification control furnace (China Patent No. ZL201310644183.6, application date 2013.12.04) was applied by the inventor on December 4, 2013. Although the firepower surpassed that of the fanless gasification furnace 1. There are fan gasification furnaces and diesel furnaces using diesel as fuel, but there are still the following deficiencies and shortcomings: (1) The space of the high-temperature gasification combustion chamber is too large, which is not conducive to energy saving and improvement of firepower. Now the refractory ring is omitted , reducing the space of the high-temperature gasification combustion chamber by about 50%; (2) The ignition hole set in the middle of the fire control cover brings inconvenience to the user, and now the ignition cover is omitted; (3) The upper large and lower small corresponding to the ignition cover The cone-shaped ignition hole of the original is now changed to a cylindrical ignition hole. Although there is no ignition cover to block the ignition hole, the diameter of the ignition hole is equal to that of other fire outlets. After the improvement, the flame will not concentrate on the ignition hole and pour out. (4) There are too many fire outlets on the fire control cover, and the diameter of the fire outlets is too small, resulting in unsmooth fire, buzzing and whistles when burning, and the fire outlets The number is reduced by 60%, and after the diameter of the fire outlet channel is enlarged by 50%, the buzzing and whistle sounds are all eliminated, and the fire is smooth during combustion; The uncombusted fuel in the chemical combustion chamber is gasified and burned in the second pass, and there are occasional peculiar smells, which is not conducive to energy saving and environmental protection, and is not conducive to increasing the furnace temperature. Increased 150-200 ℃ on the basis, fuel saving more than 15%; (6) because the inner diameter of the improved fire control ring and the middle inner diameter are greatly reduced, new problems have been caused: that is, the firepower is too concentrated in the middle of the bottom of the pot, and when cooking It is easy to burn the bottom of the pot. In order to solve this problem, a fire expansion plate is set above the fire control ring. When the flame of the fire control ring enters the fire expansion plate, because the inner wall of the fire expansion plate is heated, the flame will follow the inner wall of the fire expansion plate. The shape spreads instantly and evenly brushes towards the bottom of the pot. The invention of the fire expansion plate not only overcomes the shortcomings of the fire control circle but also develops the advantages of the fire expansion plate itself
