Air Preheater Manufacturers

1. Air Preheater Manufacturers

3. EEI has designed, factory-made and provided air preheaters with the heating price from 4000 kcal/hr to eighty,90,000 kcal/hr. • An Air pre-heater is intended to heat up air before another method with the first objective of skyrocketing the thermal potency of the method.

4. The Air pre-heating helps in Igniting the fuel, up combustion, Reducing the stack gas temperature and increasing the boiler potency. • Stability of Combustion is improved by the utilization of hot air through the Air Preheater.  • because of High heat transfer rate within the chamber and lesser heat transfer space needed. there'll be lesser un-burnt fuel particle in flue gas that the combustion potency is improved.

5. To maximize the boiler potency the helpful heat has got to be off from the gas from the APH. but bound minimum temperature has got to be maintained within the flue gas to stop cold finish corrosion.  • associate air preheater heats the combustion air wherever it's economically possible.

6. Air preheaters are often classified as restorative Air Preheaters and Regenerative Air Preheaters varietiessupported their operative principle. • In restorative Air preheaters, the heating medium is on one aspect and therefore the air is on the opposite aspectof the tube or plate and therefore the heat transfer is by conductivity through the fabric that separates the media. In regenerative Air preheaters kind the warmthing medium flows through a closely packed matrix to lift its temperature then air is more established the matrix to maximise the heat.

7. Steam Coil Air Preheater (SCAPH)EEI has provided Steam Coil Air Pre-heater (SCAPH) having heating price from 15500 Kcal/hr to thirty five,45,900 Kcal/hr. • http://www.maniks.com/manufacturer/air-preheater/

8. Steam coil air preheaters (SCAPH) ar accustomed heat air coming into the air heater restorative or regenerative kind, so as to lift the common cold finish temperature to stop acid temperature corrosion. • Finned varieties SCAPH ar wide accustomed increase the air temperature from close to the requisite temperature level by means that of saturated steam as heating medium. Steam flows within the tube whereas air passes over the finned tubes.

9. SCAPH is employed with High capability Boilers, Recovery Boilers, and Dryers for heating process-air in Sugar producing, Chemical & Allied IndustriesSCAPH is generally incorporated into the planning of a boiler unit for low load operation and startup operation notably in those areas with low close air temperatures.  • they're fascinating in this the most air heaters, restorativeor regenerative, have corrosion sections that ar a lot of promptly maintained.

10. Finned kind SCAPH form of air heater uses extended surface, unremarkably cited as fins, to scale back the size of the air preheater.  • it'susuallyplaced within the duct between the FD fan and therefore the main air heater; it's common to possess this earlier than the FD fan that might heat up cold winter air up to regarding forty degrees F.Recuperative hollow Air PreheaterEEI has designed and made hollow Air Preheater with heat duty starting from 4000 kcal/hr to eighty,90,000 kcal/hr.

11. The heat is recovered by the air from the new gas flowing across the air preheater. These form of air preheaters aris encircled rectangular kind construction consisting of many sizable amount of steel tubes of forty to sixty fivemillimetre DIA. connected or distended into the tube plates. Flue gas that is that the heating medium passes through inside the tubes and therefore the air passes although the surface of the tubes. the warmth transfer surface is giant because of low heat transfer constant between flue gas and air. Vertical flow is recommended to avoid fouling.

12. Tubular air preheaters and hollow Air Preheater with baffles ar designed, factory-made and provided to variedboiler industries as heat recovery units and conjointly to produce hot combustion air to the chamber. • http://www.maniks.com/
