Wesman Thermal Engineering Processes Private Limited Kurla, Mumbai, Maharashtra

In a furnace the re-circulation of products of combustion can substantially contribute to the speed of heating and temperature uniformity. For low temperature ovens and dryers, suitable re-circulating fans are generally provided to achieve temperature uniformity. However, fans are not practical for high temperature furnaces and kilns. Excess air can help in re-circulation but this will result in wastage of fuel. 30% excess air for a 1100 degree centigrade furnace will require additional 24% fuel than stoichiometric firing. In comparison, high velocity gases entrain and re-circulate more than seven times of own volume will eliminate need for fans or excess air.

The primary demands of a process burner are flame geometry and combustion performance maintained over wide turndown ratios to handle fluctuating load demands and spinning reserves, with minimum draught loss to conserve power. • Robust fixed geometry construction • Suitable for automatic and remote control • Able to burn oil and gas as individual fuels or combined • Ability to clean oil or gas nozzles while firing on alternative fuel • Wide turndown with good atomization • High combustion performance with low excess air • Fixed burner guns avoiding the need for retraction • Suitable for vertical, horizontal or angled application • Burns all grades of liquid fuel and wide range of gases • Low atomizing steam consumption with constant pressure over turndown range

For preparation of moulds the plant should essentially have a Continuous Mixer and Compaction Table. Sizing of the Mixer has a relationship with the size of the Mould to be prepared and the hourly production rate of the plant. Typically a no bake mould half should not take more than 20 minutes to be filled with sand mix. Based on this as well as number of moulds to be prepared per hour, the hourly capacity of the Mixer in TPH can be determined. Upstream of Rollover Machine is either a Carousel type Rotary Moulding Unit or a Fast Loop type Linear Moulding Line. In both of these, the basic purpose is to provide a time lag to the mould half so that the same gets properly cured before being stripped off the pattern. Carousel is a rotating disc with multiple waiting stations (in the form of small roller conveyors) on it. Fast Loop is a set of powered Roller Conveyors and Transfer Cars to form a closed loop along with the Rollover Machine.

altWesman Simpson Multi-Mulls are specifically designed to provide large volumes of high-quality molding sand on a continuous basis and utilizes the same effective mulling technique as the Simpson Mix-Muller.

In some operations a direct flame radiation over a large area is desirable. Luminous long flame (Fire-all) burners have considerable length and they can fill a large volume of combustion space with flame having little temperature variation along their length. This permits more effective use of hearth area because of uniform temperature head through out the combustion space. • Pre-heated combustion air up to 350 degree centigrade can be used • Suitable for Vertical Top and Bottom firing also • Range 0.53 to 7.3 Mkcalhour Application: • Bar Billet and Ingot Re-heating Furnace • Aluminum Melting and Holding Furnace • Ladle Tundish Pre-heating • Hot Air Generator • Shuttle Kilns • Forging Furnace • Rotary Kiln & Calciner

Limiting Orifice Gas Valves regulates the flow of gas in the burner for adjustment of air gas ratio. Limiting Orifice Valves are installed in upstream of nozzle mix gas burner for adjustment air gas ratio. A V-port plug is adjusted to increase or decrease of flow of gas. Limiting Orifice valves are not designed for turning off gas for which suitable shut-off valves are to be installed in the upstream.

Intensive mulling in a Speedmullor is accomplished by horizontally mounted muller wheels compressing the sand against the mixer wall. Shearing and blending is provided by a series of plows mounted on the mixer crosshead. Rotating at high speed, the combination of mullor wheels and plows provide full development of the bentonite and other additives.

Wesman has a full range of Hot Air Generators Air Heaters of both horizontal & vertical type up to a heat release capacity of 25 Million KCal per hour to offer to Cement, Chemical, Fertilizers, Minerals and Tea industries. The hot air generator shall consist of three segments, which is, the combustion chamber, the conical venturi mixing chamber and the outlet chamber. The circular combustion chamber will have the burner wall at one end. The burner shall be fitted on to the burner wall at one end of the combustion chamber that will fire directly into the chamber. The combustion chamber shall be made of two concentric shells wherein the inner shell lined with refractory material, will work as combustion chamber and the dilution air will be forced through the annular gap available between the two concentric shells.
