Description :

　　1、 Tunnel kiln waste heat boiler

　　Product Introduction

　　Tunnel kilns are widely used in the brick and tile industry, and the remaining heat is mainly the high-temperature solid waste heat of bricks and tiles. This product is located at the top of the kiln and mainly utilizes the solid waste heat from the cooling belt to generate steam or hot water for drying bricks or heating. It effectively solves the problem of excess waste heat in the brick and tile industry, reduces production costs for enterprises, and saves energy.

　　Performance Characteristics

　　① Mainly utilizing the waste heat between 800-400 ℃ in the cooling belt, without affecting the normal production of bricks and tiles;

　　② By properly arranging the heating surface, a stable temperature field will be formed in the cooling zone, and the temperature will depend on the boiler pressure and the speed of brick movement, forming a stable temperature drop curve along the direction of brick movement;

　　③ Mature design, combined with the periodic production of brick kilns, ensures boiler output and achieves full utilization of waste heat.

　　④ It has good operability, few operators, and easy equipment management.

　　⑤ Based on the structure of the kiln wall, arrange the structural type reasonably without changing the balance of smoke and air pressure inside the kiln.

　　⑥ Mainly based on radiative heat transfer, with good heat transfer effect, low steel consumption, and high cost-effectiveness;

　　⑦ The equipment has a high safety factor, reliable operation, short shutdown and renovation time, and the installation of the boiler can be completed in 7-10 days.

　　⑧ The boiler is manufactured as a whole and insulated on site, using aluminum silicate block insulation and aluminum silicate skin, with a beautiful and elegant appearance.

　　working principle

　　This boiler is located at the top of the kiln and consists of a drum, downcomer, lower header, and riser. After reasonable arrangement, it forms a self-supporting structure. After water treatment, the raw water is pumped into the drum by the feed pump and distributed to the lower header and each riser. When high-temperature bricks and tiles stop below the boiler, the riser absorbs the radiation heat of the bricks and tiles, forming a steam water mixture. Due to its low density, the steam water mixture moves upward into the drum and is separated by the drum before being led to the steam consumption point or distribution cylinder through the steam outlet pipe.
