Coal and gas burning mixed ceramic sintering process and push bat kiln

Abstract

The invention relates to a ceramic sintering process and a pusher kiln for coal-fired and gas-fired mixed firing. It is formed by transforming the existing sintering process and pusher kiln; The sintering process of the combustion method is to add a combustion chamber 4 that uses gas as a raw material to burn in the existing pusher kiln. The combustion chamber adopts a direct flame (bare burning) structure in the furnace; (Flame type); sintering uses a gas combustion chamber to directly sinter the green body. The present invention is novel in design. The process and kiln structure are simple, and the sintering process of the present invention and the pusher kiln are used to produce ceramics, which shortens the sintering time, improves product quality and production efficiency, and has a good glaze finish, which reduces the sintering cost, that is, the product quality can be improved by ten. More than 100 percent, the output is increased by nearly 1 times, the comprehensive cost is reduced by 20%, and the efficiency of the kiln is improved, the smoke emission is reduced, and the environmental pollution is improved. It is an advanced sintering process and pusher kiln for ceramic products.

Description

technical field [0001] The invention relates to a ceramic sintering process and a pusher kiln for coal and gas mixed firing. Background technique [0002] The current ceramic sintering process uses coal-fired combustion for preheating and sintering. The combustion chamber in the pusher kiln adopts a coal-fired flame-insulated (baking) structure. The kiln with this structure cannot be fired. High-temperature ceramics can only be fired with some low-temperature ceramics. The surface gloss of ceramic products is often poor, the sintering temperature fluctuates greatly, the color is uneven, the product quality is difficult to control, the consumption of raw coal is large, environmental protection is not up to standard, and the output is low. development of the ceramic industry. Contents of the invention [0003] The object of the present invention is to overcome the above-mentioned defects, and provide a ceramic sintering process and a pusher kiln with a simple production pro...
