Air pre heater
Air pre heaters Air preheater pre-heats (increases the temperature) the air supply to the furnace with the help of hot gases.are heat exchangers to preheat or air heating of the combustion air using flue gas, steam, water, or thermal oil.It is installed between the economizer and the chimney.This type of tubular type air pre-heater consists of a large number of tubes.
Flue gases pass through the tube. Air flows over the tubes. Baffles are provided to pass the air number of times over the tubes. A soot hopper is provided at the bottom to collect the soot.Working of Air Preheaters:In pre heater hot flue gases pass through the tubes of air pre-heater after leaving the boiler or economizer. Atmospheric air is allowed to pass over these tubes. Air and flue gases flow in opposite directions. Baffles are provided in the air pre-heater and the air passes several times over the tubes. Heat is absorbed by the air from the flue gases. This pre-heater air is supplied to the furnace for air combustion.
Features
- Reliability - All components of the bag filter housing are fully traceable. At Ganeshfilter, we can also tailor it to your specifications. The filter vessels are designed and manufactured following the Directive 2006/42/EC and in compliance with the EC standard.
- High-performance filtration - The path through which the fluid groes has been designed to be the shortest, facilitating cleaning. There is a wide variety of high-performance filter bags (ranging from less than one micron to several hundred microns) and the design of the filter vessel guarantees perfect sealing with the filter bags.
- Convenient and simple - The filter housing is designed to be easy-to-use. The tilting covers allow the filter bags to be changed quickly. The tripods are compact and ensure the stability of the filter vessel.
- Economical technology - Without automation and moving parts, the bag filter housing is cost-effective and economical to purchase. When compared to the flow rate, the use of a bag is often trivial compared to the volume of product filtered in the process. The bag filter is undeniably the simplest customizable filter on the market.
- Standard and custom filters - Ganeshfilter manufactures two types of bag filter housings. First, the standard vessels, which are produced in large quantities according to Ganeshfilter specifications. These vessels are not customizable but can be purchased at competitive prices. Secondly, the filter vessels tailored to our customer specifications. These filter housings are manufactured individually or in small series and the full list of options (detailed below) is possible.
