Thermal reaction caps for enhanced decomposition combustion of alcohol-based fuels

Abstract

The invention discloses a thermal reaction cover capable of promoting alcohol-based fuel decomposition combustion. The thermal reaction cover comprises a cover body used for an open type refractory ring. The cover body comprises a ring body on the exterior and a downward concave ball body in the middle. Flame holes are evenly distributed in the ring body. A through hole is formed in the center of the downward concave ball body. Three or more supporting legs are evenly distributed at the bottom of the ring body and installed on the refractory ring in a clamped mode. A gap of 2 mm-10 mm is reserved between the ring body and a hearth base. The thermal reaction cover is directly installed on the open type refractory ring in a clamped mode to form an approximately closed combustion chamber, so that alcohol-based fuel is prevented from being thrown out of a combustor; furthermore, the thermal reaction cover provides a high-temperature environment to guarantee that the alcohol-based fuel is combusted in an optimal decomposition mode, and therefore the combustion rate and the thermal utilization rate are high.

Description

(1) Technical field: [0001] The invention relates to a furnace suitable for the combustion of alcohol-based fuels, in particular to a thermal reaction cover for improving the decomposition and combustion of alcohol-based fuels. (2) Background technology: [0002] According to the implementation of the patent "Energy Saving and Environmental Protection Combustion Furnace Using Silicon Carbide Hearth" ZL201120279945.3, the open shape of the silicon carbide hearth seat matches the bottom shape of the cooking utensils to be heated, and makes the cooking utensils placed in the furnace base. The bottom of the cooker is heated at a close distance; the refractory ring is open and fitted on the burner. The burner is designed so that the flame ejected from the furnace core forms a spiral shape under the drive of the airflow, transitions from the upper end of the refractory ring to the surface of the silicon carbide hearth seat, and gradually spreads outwards from the bottom of the coo...

AI Technical Summary

Problems solved by technology

[0004] 1. The open refractory ring will cause a small part of the alcohol-based fuel that is too late to decompose and burn, and will be thrown out of the furnace by the centrifugal force formed by the spiral wind

[0005] 2. If the frying pan leaves the furnace for a long time, the temperature of the furnace will drop, which is not conducive to the combustion of alcohol-based fuels in the best way.

[0006] 3. The above phenomena will lead to a reduction in the combustion rate and heat utilization rate of alcohol-based fuels
