A RELIABLE HIGH EFFICIENCY SUGAR MILL BOILER

two old boilers required that the new boiler be of at least 120 tons steam per hour capacity on bagasse fuel. However, a 150 tph boiler would permit another old boiler to be taken offline to provide labour and maintenance savings and improved overall boiler house thermal efficiency. Tenders showed that

[PDF] A RELIABLE HIGH EFFICIENCY SUGAR MILL BOILER

A new 150 tph dual fuel (bagasse/coal) boiler was commis­ sioned in early 1984 at Tongaat-Hulett Sugar's Maidstone mill. Continuous operation for nine to ten months of the year and substantial energy exports (as bagasse, steam and electricity) from this factory led to the incorporation in the new boiler of a number of novel features likely to have application elsewhere.

Improving the energy efficiency of sugar factories: Case

The shredder, mills and the boiler drives will be electrified and the existing No. 1 boiler will be replaced with a new high efficiency No. 3 boiler operating at 65 bar(g).

A Bagasse Fired Boiler Equipped In A Sugar Mill Is - Chegg

A bagasse fired boiler equipped in a sugar mill is producing 80 MW of heat (steam power) at the operating efficiency of 62%. Combustion efficiency of the boiler is 92%. The composition of the bagasse on dry basis is: C = 48.1%; H2 = 6.25%; N2 = 0.1%; O2 = 44.4%, S= 0.05% and Ash = 1.1% The bagasse is burned with an excess air factor of 1.32 and the flue gas exits with 240°C in the stack.

Boiler Efficiency - an overview | ScienceDirect Topics

P. GoldsWorthy, E. On, in The Coal Handbook: Towards Cleaner Production: Coal Utilisation, 2013. Boiler efficiency and carbon burnout. Boiler efficiency is a measure of how effectively chemical energy in fuel is converted into heat energy in steam going to the turbines. The largest boiler efficiency loss is sensible heat lost as hot flue gases (and ash) exit the boiler.

Steam Boiler - Definition, Working Principle, Types, and

Generally, a steam boiler is a type of closed container, designed with steel for heating the water to generate steam by some energy source like burning of fuel with eventually. The vapor generated may be delivered at low-pressure for the industrial progression work in sugar industries, cotton mills, and for generating steaming water that can be utilized for heat up fixing at much low-force.

Developments in co-generation in sugar mills - EE Publishers

This is important in sugar mills where the grid supply is often unreliable and expensive. The P/H ratio in older sugar mills is typically low, of the order of 0,15- 0,3, meaning that electricity is generated from “surplus” steam and the main use of steam is for the sugar process.

BOILER EFFICIENCY GUIDE - Cleaver-Brooks

key factor is fuel usage or boiler efficiency. Boiler efficiency, in the simplest terms, represents the difference between the energy input and energy output. A typical boiler will consume many times the initial capital expense in fuel usage annually. Consequently, a difference of just a few percentage points in boiler efficiency between units
