ZENON assimilator System - A Boon to sugar factory Co-Generation
No modification, no alteration in the mill , very low power consumption, fully automatic. users friendly,
extremely economical & eco friendly.
Reducing moisture from bagasse by ZENON assimilator system technology is an optimum solution to enhance efficiency of boiler in sugar factory, though bagasse has high calorific value (NCV) but due to the moisture content (about 50 %) it is not possible to use the full heat effectively. The present work suggest to place "ZENON" assimilator at the falling chute of the milling tandem and arrest the vapour extraction piping out of the bagasse as well as from the intra-fibrous of bagasse as discharged from the last mill. Without coming in to physical contact of bagasse, the free radical escaping vapour from the freely sliding bagasse and from within the intra-fibrous of bagasse mass is extracted and condensed and discharged, thus reducing the moisture of the bagasse by < 4% which results in increase in calorific value of bagasse (NCV) and boiler efficiency.

Sugar mill engineering is a specialized branch of engineering and involves almost all the faculties of engineering - mechanical, electrical, process engineering, civil engineering, power plant engineering, thermal engineering, metallurgy, pipe line systems, pressure vessels, lifting tackles etc. This calls for a very wide knowledge on the part of the sugar engineers working in the mill. This concept specifically deals with the identification of areas of conservation of energy in the sugar factory. In broader terms, the scope of conservation of energy is applicable to almost all the points in the sugar mill - proper and timely lubrication of various mechanical transmission systems, preventive maintenance of various elements of power transmission, efficiency of hear transfer at various points of process are a few to name.
Chemical composition of dry bagasse
Bagasse % Carbon = 47, Hydrogen = 6.5, Oxygen = 44, Ash = 2.5
Gross calorific value (G.C.V) of dry bagasse
8280 B.T.U./1b = 4600 kcal/kg
Nett calorific value (N.C.V) of dry bagasse
7650 B.T.U./1b = 4250 kcal/kg
Most conspicuous of all these processes 'wasting' energy is the amount of moisture contained in bagasse leaving the last mill roller and fed to the boiler / s for combustion to generate steam and consequently electric power. The moisture carried with bagasse takes away major part of the useful heat energy generated in the boiler / s by combustion of bagasse. Hence, the top most priority in the area of energy conservation in a sugar mill is to reduce the moisture content in bagasse before it is fed to the boiler / s. 1% reduction of approximately moisture in bagasse increases 0.5% boiler efficiency. Hence removing of moisture from bagasse will enhance boiler efficiency proportionately.
