DZH manual type moving grate coal/biomass boiler. DZH Series Boiler, is a manual type coal/wood feeding system boiler, water-fire tube sturcture & wing shape flue. It has strong fuel adaptability for solid fuel: coal, wood log, wood chip, wood waste, coal and solid fuel. Cross-feed (travelling-grate) boilers are more commonly used with smaller scale industrial boilers. Spreader stokers. In spreader stokers, the fuel is propelled into the furnace. A portion of the fuel burns in suspension while. Combustion in Boilers Manual Ver 3.6 December 2011 3. CHAPTER TWO: Boiler Operation Maintenance & Safety Study Guide 2.1 Boiler Design and Construction Boiler: A boiler is a closed vessel in which water is heated, steam is generated, superheated or any combination thereof under pressure or vacuum by the direct application of heat from combustible fuels or electricity. The steam produced is used for.

FBC ADVANTAGE OVER CHAIN GRATE STOKER BOILER
FBC( FLUIDIZED BED COMBUSTION) boiler have great advantage over mechanical chain grate Stoker fired boiler. We discussed about the merits of FBC boiler during operation.
1.Reduction in boiler size :-
in FBC boiler bed coil are installed so the more temperature gain from the fuel combustion and other side mechanical chain grate boiler no bed coils are there so high heat transfer rate over a small heat transfer are immersed in the bed result in overall size reduction of the boiler.
2.Ability to burn fines :-
In FBC boiler coal contain fines below 6 mm can be brunt efficiently which is very difficult to achieve in conventional type firing system.
3.Easier ash removal – no clinker formation:-
In FBC boiler furnace temperature is near about 750 – 900 degree Celsius, even coal of low ash fusion temperature can be brunt without clinker formation. Ash removal is easier as the ash flow like liquid from the combustion chamber. So less manpower is required for ash handling.
4.Pollution control:.-
In FBC boiler so2 formation can be greatly minimizing by addition of limestone or dolomite for higher sulphur coal contains 3% limestone is required for every 1% sulphur in the coal feed. Low combustion temperature eliminate NOx formation.

5.High efficiency :-
Fbc boiler can brun fuel with a combustion efficiency of over 95% irrespective of ash content. Fbc boiler can operate with overall efficiency of 84% .
6.Fast response rate against load fluctuations:-
Due to high furnace temperature inherent high thermal storage characteristic can easily absorbed fluctuations in fuel feed rates.
7.High reliability:-
In FBC boiler bed no moving part is available in the combustion zone result in a higher degree to reliability and low maintenance cost.
8.Reduced maintenance:-
Routine overhaul are infrequent and high efficiency is maintained for long periods.
9.Provision of automatic ignition system:-
Control system using microprocessor and automatic ignition equipment give excellent control with minimum manual supervision.

10.Provisions of automatic coal and ash handling system:-
Automatic system for coal and ash handling can be incorporated, making the plant easy to operation comparable to oil and gas fired installation.
