Heavy Oil Clay Brick Firing Kiln Tunnel Kiln 31 Hours Firing Cycle

1. Brief introduction

Clay brick tunnel kiln is the most popular thermal kiln for baking building bricks because of its characteristics of continuous operation, stable thermal performance, high efficiency and stable quality. Compared to the traditional external tunnel oven, this oven has a larger cross-section and a shorter cooking cycle. clay brick tunnel kiln consists of kiln body, kiln car and conveyor equipment, combustion system, air exhaust system, control system, etc.

It adopts heavy oil as fuel to baking the bricks. The burning system adopts circulation return pipeline arrangement. The heavy oil is heated before supplied to each group of burners. The whole burning system is managed by computer system.
