SZL coal fired boiler, adopting the membrane water-cooled wall system and water cooled system, is a solely developed machine in ZG which absorbs all the previous advantages. It applies the water-cooled arch system and membrane water-cooled technology to shop-assemble water tube boiler,which is the initial technology in our country.

In the manufacturing of packaged boilers,rows of tubes are placed on the vertical walls of the boiler box, and the box is welded shut.This is one type of tubing arrangement on the front wall of a water-cooled boiler. According to the structural type, there are three main types of water-cooled wall,bare pipe,membrane type and finned tube type.

Packaged Boilers with Water-cooled Furnace A layer of insulating refractory material is a common feature of packaged boilers. Usually, this refractory lines the walls and floor of the unit, preventing damage to those parts of the boiler casing (outer wall).

membrane wall construction eliminates the need for refractory and enables quick start-up to achieve full steam capacity of the boiler in a fraction of the time that it takes with older designs. In addition to significantly reducing maintenance and operating costs, a water-cooled membrane wall furnace offers further benefits in reducing emissions.

The SZS is a typical D-type water tube boiler design, Bi-drum packaged gas & oil fired boiler. It is mainly composed by upper-drum (steam drum ) & lower-drum(water drum), membrane water cooling wall, convection bank, economizer, and condenser.

In this article we will go through the basic furnace walls designs used in constructing a boiler. The type of material used in the the furnace walls of the boilers is known as refractory material. The refractory acts as both an insulating material and a protective layer for preventing the external walls of the boiler from getting damage.

4). It is good to adopt top supported water cooled wall and it could reduce the load of boiler framework, which is benefit to overhang. 5) Compared with the bare tubes, the membrane water wall improves the heat absorption capacity of tubes.
