Introduction

SZL series boiler is the horizontal dual cylinder arranged, chain grating, pipe steam and hot water boiler designed by our technical personnel according to advanced technology and experiences from home and abroad. The technology performance and environmental protective index of this series of products reach the international advanced level, and this product is the mainstay one in boiler industry.

The boiler uses quick fitting or assembly structure. The 4-6th boiler is of quick fitting pipe structure, exit shop after completely assembled, the boiler of 6-35t/h is composed of 2 main components: The upper assembled components is the body heat accepting part, and the lower assembled component is of combustion equipment. The former part of the boiler body is arranged an water cooling wall, the upper part of it is connected to boiler cylinder, and its lower part is connected to collective chest, so as to form a combustion room and absorb the radiated heat from the furnace; its rear part is arranged with dense convection pipe bundle between upper and lower boiler cylinders;the high temperature smog after combustion shall be stand for twice returning to coal saver singly arranged ,and flow into duster and exhausted from chimney in the end. The 20t/h assembled water pipe boiler is composed of front furnace, rear furnace,convection pipe bundle, coal saver and chain grating,and which are assembled in big components respectively for delivery.

This series of boiler absorbs the merits from quick fitting boiler, features compact in structure, the boiler’s shop is of one storey arranged, convenient for site installation, short in construction period, cheap in cost, simple in operation and etc.
