ASME or EN standard boiler water wall fabrication with manhole and qualified certification

Water Tube Boiler Description

Water tube boiler is a type of boiler in which water circulates in tubes heated externally by the fire. Fuel is burned inside the furnace, creating hot gas which heats water in the steam-generating tubes. In smaller boilers, additional generating tubes are separate in the furnace, while larger utility boilers rely on the water-filled tubes that make up the walls of the furnace to generate steam.

Water wall Panel Introduction

Boiler furnace is that part of the boiler where the temperature of the system reaches the highest. The furnace produces the necessary heat required by burning the fuel oil inside its small closed chamber. Because of the fuel combustion the internal temperature goes extremely high and for this reason it is necessary that the walls of the furnace are stacked with proper high temperature withstanding material. In this article we will go through the basic furnace walls designs used in constructing a boiler.

Advantages

1. The protective effect of membrane water cooling wall on the furnace wall is the most complete, so the furnace wall only needs insulation materials, rather than refractory materials, so that the thickness and weight of the furnace wall are greatly reduced, simplify the structure of the furnace wall, reduce the total weight of the boiler.

2. Membrane water wall also has good air tightness, can adapt to the requirements of positive pressure combustion on the boiler, not easy to slag formation, less air leakage, reduce the heat loss of smoke exhaust, improve the boiler thermal efficiency.

3. it can be welded into components by the manufacturer for quick and convenient installation.

4. the use of membrane wall structure of the boiler, simple maintenance, boiler service life can be greatly improved.
