wet exhaust systems fluidised bed boiler slag

Mechanical Engineering Interview Questions &

2019-6-19 · Bubbling fluidised bed combustion (BFBC) has a defined height of bed material and operates at or near atmospheric pressure in the furnace. Pressurised fluidised bed combustion (PFBC) system operates the bed at elevated pressure. Exhaust gases have sufficient energy to power a gas turbine, of course, gases need to be cleaned.

An Overview of Atmospheric Fluidized Be

The heat output available from a fluidized bed boiler depends on the bed area and the fluidiuing velocity. Figure 4 presents the approximate bed area and heat release rate needed to provide tie thermal output at a given fluidizing velocity. If the required bed area is similar to the existing boiler

Use of circulating fluidized bed combustion fly as

Circulating fluidized bed combustion (CFBC) fly ash and slag are wastes from CFBC power plant, and have such a high sulfur content (usually more than 5% SO 3 by weight) that would result in a great risk of destructive expansion when used in building materials, which are produced in normal temperature. This work investigated the preparation conditions of autoclaved brick with CFBC fly ash and

Slagging in Fluidized Bed Combustion of Rubber Tir

This slag formation by bottom ash agglomeration caused important operational problems because the gas speed was not high enough to achieve the fluidization of such big particles. Usually, they remained at the bottom of the bed while the rest of the ashes were fluidizing, causing frequent operational problems.

Fluidized bed combustion - Wikiped

2019-6-14 · Fluidized bed combustion (FBC) is a combustion technology used to burn solid fuels. In its most basic form, fuel particles are suspended in a hot, bubbling fluidity bed of ash and other particulate materials (sand, limestone etc.) through which jets of air are blown to provide the oxygen required for combustion or gasification.
