An Industrial Furnace with Improved Fuel Utilization Efficiency

Abstract

The invention discloses an industrial furnace capable of improving the fuel utilization ratio. According to the industrial furnace, a shell and a movable block are disposed at the top of a base; an opening is formed in the side, close to the movable block, of the shell; a fuel tank is located at the top of the shell; a feeding channel is formed in the position, at the bottom of the fuel tank, of the shell; an S-shaped pipe is connected to the bottom of the feeding channel; a threaded rod is disposed in the middle of the feeding channel; an air inlet pipe is located on the side surface of the shell; a cam is located in the middle of the air inlet pipe; and an air outlet pipe is located on the inner wall of the shell. Fuel gradually enters the shell through thread lines on the threaded rod,and the purpose of uniform feeding is achieved; through the S-shaped pipe, the safety in the combustion process is improved; through the air outlet pipe with the smaller hole diameter, the air flow speed is increased, the air is fast blown to the whole interior of the shell, thus fuel which falls down from the fuel tank is in full contact with the air, the fuel is dispersed by blowing of the air,the phenomenon of incomplete fuel combustion is reduced, and the fuel utilization ratio is improved.

Description

technical field [0001] The invention relates to an industrial furnace, in particular to an industrial furnace for improving fuel utilization. Background technique [0002] Industrial furnaces: Industrial furnaces can be divided into two types according to the thermal system: one is intermittent furnaces, also known as periodic furnaces, which are characterized by intermittent production of furnaces, and the furnace temperature in each heating cycle is Changes, such as chamber type furnaces, trolley type furnaces, pit type furnaces, etc.; the second type is continuous furnaces, which are characterized by continuous production of furnaces and division of temperature zones in the furnace chamber. During the heating process, the temperature of each section is constant, and the workpiece gradually enters the high-temperature heating zone from the low-temperature preheating zone, such as continuous heating kiln and heat treatment kiln, annular kiln, walking kiln, Bottom-shaking f...

AI Technical Summary

Problems solved by technology

[0003] Existing industrial furnaces have certain defects in the process of use. For example, when industrial furnaces use electric energy for heating, due to the high energy consumption in the process of converting fuel into electrical energy, the conversion of electrical energy into heat energy consumes a part , which in turn increases the combustion cost of industrial furnaces. If the fuel is directly heated, the fuel will accumulate and incomplete combustion will occur, which will affect the heating effect and cause fuel waste
