We monitor the combustion and enhance the boiler efficiency
M/s. Altret Industries Pvt. Ltd., Surat in technical collaboration with S.V.N.I.T., Surat, started to work in this area since 1992 and through extensive AR&D efforts launched ALTRET 95 & 2K Series of Combustion Monitoring Chemical/Fuel Additives in the market.
This highly advanced series of fuel additives have many desirable qualities such as CATALYTIC EFFECT for improved combustion, ANTI-FOULING & ANTI-CLINKERING property for better heat exchange and dual effect, oxidation & reduction catalyst for lowering the emission levels.
Key Characteristics of ALTRET 95 & 2K Series Combustion Monitoring Chemicals/Fuel Additives for Solid Fuel
- It acts as combustion catalyst and thereby improves combustion efficiency. Loss due to unburnts in ash gets minimized with the use of this chemical.
- It permits boiler operation at reduced excess air levels, which in turn reduces stack losses.
- It acts as anti–fouling agent and thereby keeps heat transfer surfaces clean and thus improves the steam generation for same heat transfer area.
- It softens the hard clinker and reduces the tendency of hard clinker formation. This property helps in reducing the boiler maintenance, provide ease in cleaning and increase the boiler availability for long term operation.
- It minimizes the escape of unburnt volatiles with flue gas. This not only reduces the unaccounted losses, but also reduces the emission levels.
- It helps in reducing stack emission levels through dual effect oxidation & reduction catalyst.
- It improves the conductivity of ash and thereby improves ESP performance and reduces SPM levels in stack.
How ALTRET CMC 95/2K Series Combustion Monitoring Chemicals Works?
Combustion efficiency is governed by fuel quality (Ash Contents, Carbon, Sulphur, Hydrogen, Nitrogen, Oxygen, Volatile Matters, Moisture, and C.V. etc.), excess air ratio, bed height, particle size, air velocity, furnace configuration and complete oxidation of carbon. The thermal resistance of heat transfer surfaces depends on tube material, waterside scaling, fireside fouling, particle morphology, presence of volatile and temperature gradients.
The combustion efficiency of boiler/heat producing system can be improved by using ALTRET CMC 95/2K Series combustion catalyst. The improved combustion will not only improve the overall efficiency but also reduce the emission level of the system. ALTRET additive also alters the particle morphology, which reduces the Accretion or Coating, Fouling and Clinkering tendency of ash by changing the eutectic structure of ash and thus the thermal efficiency is improved.
The Selective Oxidizing catalyst of ALTRET CMC 95/2K Series Combustion Monitoring Chemicals/Fuel Additive provides better pore surface area by penetrating into fuel particles to convert normal fuel particle in to advanced catalyzed fuel particle. It provides high rate of oxygen penetration along with enhanced surface area obtained through advanced catalyst.
Antifouling effect may be obtained by changing preferred direction of orientation of particles, by forming a protective layer of vapors on surfaces and by retarding ash reaction leading to formation of clinkers and formation of Sodium and Potassium Sulphates and Pyrosulphates.
Suitably co-coordinated ALTRET fuel additive can certainly improve the overall performance of heat exchange equipment like boiler through catalytic and anti-fouling effect.
The increased awareness towards EURO compliance and foreseen crisis of fossil fuel ALTRET launched ALTRET CMC 95/2K Series Combustion Monitoring Chemicals/Fuel Additive in 1992.
Criteria to Judge Performance Evaluation of CMC 95/2K Series Combustion Monitoring Chemical (CMC)TM/Fuel Additives
- Reduction in clinker formation and ultimately reduces boiler outage – avoid generation loss.
- Reduction in fouling and clinkering tendency.
- Reduction in unburnt carbon particle in fly ash as well as in bottom ash %.
- CMC chemical is alkaline in nature and reacts with sulphur of lignite and neutralizes the acid attacks in the rear end zone of the boiler. As a result, performance of ESP improves and corrosion effects on APH and ID impeller fan will be minimized.
- Because of perfect combustion, the ash quality improves due to reduction in unburnt carbon in ash so that ash quality improves and hence it will be usable to cement industry.
- Because of perfect combustion and better performance of ESP chimney will be clean and avoid environment problems like SO2 & SPM.
- Attemperator spray will be reduced due to removal of fouling.
- Because of reduction in fouling, the system resistance will be reduced and some marginal reduction in auxiliary power will be observed in terms of ID & FD fans.
