Delair provides solution for Ash Handling System
Delair has been able to save production and energy cost for many thermal and cement plants by installing its wide range of Refrigeration & Adsorption based Compressed Air Dryers and Customized / Engineered Adsorption based compressed air dryers. Some of the satisfied customers who have installed Delair Dryers in their manufacturing units include:
- NTPC
- Rajasthan Vidhut Nigam Ltd
- APGENCO
- Hindalco Industries
- West Bengal Power Corporation Ltd
- Ennore Thermal Power Station
- Indraprastha Power Station
- Tamil Nadu Electricity Board
- MAHAGENCO
- Himachal Pradesh State Electricity Board
Process of Ash Handling System
Bulk material is conveyed by air under pressure. This system offers advantages of conveying material from one point to another or to a number of discharge points. The system is composed of a blower or a fan, rotary lock, cyclone separator, divertor, piping and fittings bag filter. Pressure conveying system needs dry compressed air to transport dry fly ash from the surge hopper to the silo for ash storage. Here, the dry ash is mixed with the compressed air and then the mixture is conveyed through the pipeline which runs upto the storage silo where the ash is discharged and the air is released into the atmosphere after filtration. If moisture is present in the compressed air stream, the ash gets moistened, sticking to the sides of the pipeline leading to scale formation and corrosion of pipes
Moisture in compressed air stream leads to
- Corrosion in pipes, ash intake valves, air intake valves and other components.
- Increased downtime and maintenance costs of pneumatic controls
- Contamination and damage at points where the compressed air comes directly in contact with sensitive materials
- Rust and scale formation in pipelines, silos
- Sluggish and inconsistent operation of air valves
- Malfunctioning of pneumatic shutters
The Delair Solution
There can be tremendous saving of energy costs, if the compressed air is dried upto 2 to 5 °C PDP (Pressure Dew Point) i.e corresponding to (-)20°C ADP (Atmospheric dew point) instead of (-) 20°C PDP corresponding to (-)40°C ADP respectively. For most cost effective removal of moisture from the compressed air stream. Delair engineers suggest installation of Refrigeration Type Dryers since in Heatless Type Dryers air is wasted for purges process of regeneration of the towers.
Delete moisture from compressed air
Moisture in compressed air may leads to
- Malfunctioning of pneumatic tools and machines
- Sluggish and inconsistent operation of valves and cylinder
- Corrosion in pipe lines, cylinder and other componentsIncrease in downtime
- Increase in maintenance cost of pneumatic machines / tools / controls
- Freezing in exposed lines during cold weather.

SOLUTION
Remove water, dust particles, oil (oil particles are introduced by lubricated air compressors) and solid contaminants from compressed air. So that moisture free air can be used for different applications.
The Delair Solution
Delair offers wide range of Refrigeration dryer, Adsorption dryers and Customized / engineered Adsorption dryers which removes water / moisture from compressed air
Delair Refrigeration Dryers
This dryer operates on the method of cooling the air to near freezing point to remove the moisture and reheating it to approximately 10°C below the incoming compressed air temperature at nominal conditions.
Delair Adsorption Dryer
Adsorption dryers is based on the principle of heatless regeneration and the physical properties of ther desiccant to adsorb and desorb the water vapour, It uses pressure swing principle / purge air to regenerate the desiccant bed.
Filters
Delair also offers Pre Filters and Oil Filters which removes dust particles, oil particles and other types of solid contaminated present in compressed air.
Delair – recent projects
Delair successfully supplied the Refrigeration based Compressed Air Dryer for 4000 MW Ultra Mega Power Project for “Coastal Gujrat Power Limited”.
