AIR HEATERS
Steelsworth
Concept
Steelsworth Air Heater is an improved form of the basic concept of hot air generating system. Ambient air enters into the air heater from the side top and being heated from the hot surfaces, it flows into the drying chamber being drawn by the drier's hot air fan. Flue gases are drawn by the Induced Drought Fan through the two vertical rows of tube banks on either sides of the furnace area and casting surfaces to the chimney. In Steelworth Air Heaters ambient air passes through triple passes and flue gas passes through five passes. These multiple passing of ambient air and flue gas in this improved design with compact and planned inner surface provides excess heat in the hot air.
Quality Castings
All Cast iron parts are made from special heat resistant and superior quality castings so as to ensure their withstanding capacity at high and temerature. Use of graded castings also eliminates rapie detoriation of castings in and around the furnace area and gives much durability assurance.
High Thermal Effiency
Steelsworth Air Heaters are designed for better heat transfer. Our FIVE PASS model is more efficient than the SOUBLE PASS model as flue gas passes five times before escaping into the atmosphere and so the flue gas temperature is reduced which provides higher thermal efficiency. Since the flue passes through the tubes instead of over them, these tubes can be cleaned and maintained for better heat transfer. The net efficiency varies from 55% to 70% depending on the mode.
Multiple Fuel Provisions
Steelsworth Air Heaters are easily operatable with different kinds of solid fuel (viz. wood, coal, leco, briquetted waste, bagasse etc.), liquid fuel (viz. light distillate, heavy furnace oil) and gas firing.
Optional Stocking System
Besides manual stoking Steelsworth Air Heaters can be conveniently fitted with mechanical stoking system. This helps in precise degree of control of feeding of coal for maximum heat extraction and consistent temperature.
Steelsworth Induced Draughts Fans
Steelsworth Induced Draught Fans of four different sizes are specialy designed to suit with Steelsworth Air Heaters for perfect passing of flue gas which is one of the important aspects for better thermal effciency. We recommend Steelsworth Induced Drautht Fans to achieve the highest performance of Steelsworth Air Heaters.
