Blaze insulating fluidized forge furnace

Abstract

The invention is about the fire stove, which concerns fire equipment technique field. The invention makes use of firing heat the stove indirectly, avoiding the direct contact of fire and material, so it overcome the material over fire phenomenon, at the same time, the smoke go to the stove up to down, increasing the heat time for a time. Compared with the fire material directly, it increases the heat effect by much time. The material in the invention can stop for some seconds to hours, the temperature of the stove is 500-1300 degC, the difference in temperature is between minus 5 and plus 5 degC. The invention transfers the heat fast, the temperature in the stove is even, and it uses low energy.

Description

technical field [0001] The invention relates to a flame-insulated fluidized calciner, which relates to the technical field of calcining equipment. Background technique [0002] At present, calcining equipment includes fluidized bed calcining furnace, rotary kiln, multi-layer furnace, tunnel kiln and so on. For the calcination of powder materials, the fluidized bed calciner has fast material heat transfer and mass transfer, low energy consumption, and large production capacity of a single equipment, but the existing fluidized bed calciner heating method is directly heated inside the furnace or a combustion chamber is set outside. , which leads to the following problems: First, the fuel burns in the furnace, the flame is in direct contact with the material, the flame stability is poor in the dense phase, and the local temperature in the furnace is too high, which makes the surrounding material heated to a high temperature, resulting in overburning of the material; in addition,...

For the calcination of powder materials, the fluidized bed calciner has fast heat transfer and mass transfer, low energy consumption, and large production capacity of a single equipment, but the existing fluidized bed calciner heating method is directly heated inside the furnace or a combustion chamber is set outside. , which leads to the following problems: First, the fuel burns in the furnace, the flame is in direct contact with the material, the flame stability is poor in the dense phase, and the local temperature in the furnace is too high, which makes the surrounding material heated to a high temperature, resulting in overburning of the material; in addition, When the fuel is burned in the external combustion chamber, the heat is released to the outside, and the heat dissipation is large, and the effective utilization rate of heat is reduced.
