Major types are centrifugal blower and positive-displacement blower.Centrifugal blowers look more like centrifugal pumps than fans. The impeller is typically gear-driven and rotates as fast as 2900 rpm. In multi-stage blowers, air is accelerated as it passes through each impeller.In single-stage blower, air does not take many turns, and hence it is more efficient. Centrifugal blowers can achieve higher pressures up to 1500 mmWC

Specially designed Limiting Orifice valve by THERM PROCESS is mainly used to set desired Gas / Air flow at the nozzle mix burner. The flow can be adjusted precisely with screw driver. Turning of screw Counterclockwise / clockwise will increase / decrease the gas flow respectively.

the system is specifically designed for curing of delta monolithic lining. The total installation requires space of about 12 sq.mtr & can be conveniently located in sms bay.

the typical curing cycle shall be 36-48 hours as recommended by refractory supplier

the duly lined delta shall be placed on circular support casing with combustion chamber.

a monoblock burner suitable for lpg/png is fitted on combustion chamber. The burner operation is totally automatic with built in blower, auto ignition & auto cut off.

once the delta is placed, the burner can be started with "burner on' push button provided on control panel.

the temperature controller provided on panel can be programmed to 8 ramp / soak cycles. The burner shall operate as per signals from temperature controller & thermocouple.

at the end of the cycle system stops automatically.

• Therm process is pleased to introduce New Oxygen washing control system to save costly Oxygen / Argon / Nitrogen

• Process

  Normally Oxygen washing operator cannot see Argon / Nitrogen purging process as both are on opposite side of Laddle.Oxygen washing operator does not know if porous plug is cleaned or not hence keeps Oxygen flame ONThereby damaging costly refractory & causing wastage of Oxygen.
• Similarly Argon / Nitrogen purging process is not sure whether the plug is cleaned, hence keeps unnecessarily Argon supply ON
• The stopping of Oxygen & Argon is mostly carried out by assumptions & approximation.

Improvement

A Control box is provided with valves to regulate Argon / Nitrogen flow.Existing Argon / Nitrogen line shall be connected to control box inlet & outlet shall be connected to Ladle porous plug point.A flow switch & Argon solenoid valve is provided in control box.When plug is cleaned the Argon / Nitrogen flow starts.This gives flasher signal to Oxygen washing operator to stop.The signal also stop Argon gas automatically through solenoid valve.

AdvantagesReduced Oxygen consumption at washing by 20%.Unnecessary erosion of Refractory is eliminated.Reduced Argon / Nitrogen consumption by also 50%.Operator Firendly.

Details :

• For Waste heat recovery the Recuperator is provided in the flue duct between furnace & chimney
• By passing combustion air through recuperator , air can be preheated before entering furnace from burner.
• It is a special purpose counter flow or cross flow energy recovery heat exchanger.
• It is possible to recover 60-70 % of the waste heat and preheated air upto 150 to 500 C

Precise control valve designed by Therm Process mainly used to set desired oil flow at the nozzle mix burners.

Air- oil Ratio Regulator is used to control the Furnace temperature by controlling oil flow through burners.

Aluminum Melting / Holding Furnace ( Skelner Furnace)

This melting and holding furnace is designed for continuous operation and is suitable for aluminum die casting aluminum casting industries

Equipped withTherm Processs Super Low Speed Luminous Flame Burners in the melting furnace. Electric heaters are used in the holding furnace.

Attractive Features

No Hard Oxidation Material, the temperature in the holding chambers is kept at about 50 c higher than that of molten metal. This minimizes possibility of formation of hard oxidation of material caused by over temperature condition.

Low Energy Cost

Long Heater Life

Low Maintenance cost & small space utilization

Superb working condition
