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

Boiler Application

1. The ability of watertube boilers to generate superheated steam makes these boilers particularly attractive in applications that require dry, high-pressure, high-energy steam, including steam turbine power generation.

2. Variety of process applications in industries.
3. Chemical processing divisions.
4. Pulp and Paper manufacturing plants.
5. Refining units.

6. Besides, they are frequently employed in power generation plants where large quantities of steam (ranging up to 500 kg/s) having high pressures i.e. approximately 16 megapascals (160 bar) and high temperatures reaching up to 550 °C are generally required. For example, the Ivanpah solar-power station uses two Rentech Type-D watertube boilers

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.
