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 veritical rows of tube banks on either sides of the furnace area and casting surfaces to the chimney. In Steelworth Air Heater 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 part are made from special heat resistant and superior quality castings so as to ensure their withstanding capacity at high heat and temperature. Use of such graded castings also eliminates rapid detoriation of castings in and around the furnace area and give much durability assurance. |
| |
| High Thermal Efficiency |
| |
| Steelsworth Air Heaters are designed for better heat transfer. Our FIVE PASS model is more efficient than the DOUBLE PASS model as the flue gas passes five times before escaping into the atmosphere and so the flue gas temperture is reduced which provides higher thermal effciency. Since the flue passes through the tubes instead of over them , these tubes can be cleaned and maintained for better heat trasfer. The net efficiency varies from 55% to 70% depending on the model. |
| |
| Multiple Flue Provisions |
| |
| TSteelsworth Air Heaters are easily operatable with different kind of solid flue (viz: wood, coal, leco, briquetted waste, bagasse etc.),liquid flue (viz: light distillate, heavy furnace oil) and gas firing. |
| |
| Optional Stocking System |
| |
| Besides manual stoking Steelsworth Air Heater can be conveniently fitted with machanial sotking system. This help in precise degree of control of feeding of coal for maximum heat extraction and consistent temperature. |
| |
| Steelsworth Induced Draughts Fans |
| |
|
| Steelworth Induced Draughts Fans of four different size are specially designed to suit with Steelworth Air Heater for perfect passing of flue gas which is one of the important aspacts for better thermal efficiency. We recommend Steelworth Induced Draught Fan to achieve the highest preformance of Steelsworth Air Heaters. |
