Circulating Fluidized Bed (CFB) combustion boilers gives the flexibility for combustion of a wide range of coals and alternative fuel sources. All this without compromising efficiency and with reduced emissions. This article gives a brief description of the working of a CFB boiler. At the bottom of the boiler furnace there is a bed of inert material.
Types of Industrial Boilers According to Function Boilers can be designed for two functions: to produce hot water or steam. Industrial boilers will always be used for steam production, which is a vital resource for different industrial applications such as turning turbines for power generation and heating kilns in cement plants.
The fluidized bed boiler is gaining in popularity and has overtaken the grate-fired boiler in biofuel power generation applications. The principle is very simple: air is blown through a bed of sand and fuel particles at a velocity that is sufficient to suspend the particles on the airstream but not able to lift them permanently out of the bed
The openings of the grate must not be so large that they allow the unburned fuel partials to fall through and on the other hand these openings must not be so narrow that they obstruct sufficient amount of air to pass through the fuel.. Firebox and Combustion Chamber of Furnace. Firebox of boiler furnace is the place just above the grate and combustion chamber is the extension of this where

The aforementioned boiler types typically fall into one of the following combustion method categories: Stoker Stokers burn lump coal. Spreader stokers feed a continuous supply of coal onto the bed. A chain-grate stoker (sometimes called a traveling grate stoker) deposits the fuel in one area where it is then distributed by a moving grate
The traveling grate is comprised of chain that carries the pellets like a conveyor. The difference is that the grate chain allows air to pass through it. The grate chain travels flat and strait. There are several compartments the pellets are exposed to different heat. Once the pellets are discharged into the kiln the grate chain returns underneath.
boiler equipment, smaller unit size preventing economies of scale, and slightly lower efficiencies. However, recent growth in thermal capacity, aided by the move to supercritical steam conditions, and optimisation of the technology have allowed boiler costs to drop more in to line with PCC -a highly
Our grates provide waste flow that ensures drying, ignition, combustion, energy release and complete burn-out before the bottom ash outlet. In a waste-to-energy plant, the grate is where waste is converted into energy - the heart of the system. The combustion grate plays a vital role. As such, grates are a significant focus area for us.

The combustion of biomass, in this case demolition wood, has been investigated in a grate combustion multifuel reactor. In this work a temperature range of 850-1000 °C is applied both for staged air combustion and nonstaged combustion of biomass to investigate the effects of these parameters on the emission levels of NOx, N2O, CO, hydrocarbons (CxHy) and different other components.

Moving-grate incineration requires that the grate be able to move the waste from the combustion chamber to allow for an effective and complete combustion. A single incineration plant is able to process thirty-five metric tons of waste per hour of treatment. The MSW for a moving grate incinerator does not require pretreatment.
Flue Gas Waste Heat Boiler Thermal Efficiency Calculation 2017-10-04 17:02:11. Boiler heat efficiency refers to the heat input into the boiler, most of which are absorbed by the boiler heating surface to produce water vapor, which is the heat that is effectively utilized, and the remaining heat is called heat loss. The heat efficiency of a flue gas waste heat boiler is the percentage of the
