Hi-Therm's Furnace Gas Burner series used on almost any kind of Industrial Furnace, Ovens, Air Heaters and Kilns. Due to their unique design, the Furnace Gas Burners give a higher temperature output. These burners are nozzle mix type burners which work best on LPG. They provide a medium velocity flame with wide air to fuel ratio and turndown flexibility.

Furnace Gas Burner is made of cast iron body which makes them highly robust, and with a gas connection they deliver a steady, reliable and proven performance. The air tube is made of Stainless Steel material for higher temperature application, which is an Inconel material. These burners also have an observation port in the back of the gas connection and a provision for pilot gas burner and flame detector.

Furnace gas burner is also available in fully automatic operational models with an Auto Ignition system, Hi-Therm’s Sequence Controller and an Ionization Rod/UV Cell as the flame supervisor. They are also available in On/Off models or High/Low models which are PID controlled with the incorporation of flame controller.
Hi-Therm has sucessfully manufactured, supplied and installed several Furnace Gas Burners across India as well as in the Middle East and the African regions.

Air to Fuel ratio control using Limiting Orifice Gas Valve :


Limiting Orifice Gas Valve Hitherm

The Limiting Orifice Valve is used to set air/gas ratio on a nozzle-mix furnace gas burner. It has a V-port plug that is highly sensitive and accurate, and can be adjusted simply with a screw driver. Turning the screw counter clockwise increases the flow. A cap conceals the adjustment and prevents tampering with the setting. If an adjustment is needed, replace top cap on valve body to reduce air or gas leaks. The V-port adjustment is in a removable gas cartridge assembly, which simplifies inspection or replacement. Depending on the type of gas, the internal metal is selected. Limiting Orifice Valves provides “fine tuning” for air/gas ratio adjustment.

Limiting Orifice Valves are not designed for shutting off gas, for that purpose, an approved plug valve or cock is used. They are installed as close to the Furnace Gas Burner as possible. The correct size of valve is selected, to suit the capacity of the gas flow required. For various gas capacities, the Limiting Orifice Valves are designed from ½” to 3″ Size and are in BSP Female thread connection.

A Simple Gas Train is explained as under:
Main Shut Off Ball Valve – Gas Filter – Pressure gauge – Second Stage Pressure Regulator – Pressure Gauge – Solenoid Valve – Limiting Orifice Valve – Burner

Safety features like Gas Pressure Switch, Slam Shut off Valve, Leak Test Detector and others can also be incorporated depending upon the installation requirements.
