Manifold Header Water Wall Panel with convection heat surface

Boiler Water Wall Panel with Manifold Header for Sugar Mill Boiler Maintenance in ASME Standard

Introduction

Boiler water walls are membrane walls that are made of tubes welded together with or without a strip of metal in between. These walls form the enclosure of the coal combustion chamber. Water wall tubes are also referred to as the evaporator section; they contain water mostly in liquid form which gradually evaporates as it rises in the boiler.

Specification

The main function of water wall panels in boiler is to absorb the heat generated by high temperature flame or flue and to generate steam or hot water in tubes, hence to reduce the temperature in the chamber .

Application

The water wall is the main radiation heat surface, arranged inside the boiler chamber and proceeds the heat exchange directly with the high temperature flame. The convection tubes are the convection heat surface of the boiler, arranged between the boiler chamber outlet and the end surface and proceed the heat exchange directly with the high temperature fume.

The accessories and detailed information

A waterwall in a boiler is any furnace wall that is comprised of refractory and tubes in a water-tube boiler. The tubes are evenly spaced and generally connectto headers which in turn are connected back to the main generating bank of the boiler.
