What is a Gas Fired Furnace?

A gas fired furnace uses combustion of fuels such as PNG (Piped Natural Gas), LPG (Liquefied Petroleum Gas), or diesel to generate high temperatures required for thermal processes in metallurgy and materials engineering. These furnaces are well-suited for high-load, long-duration applications where cost-effective heat delivery is essential. Maan Global Industries is among the top 10 gas fired furnace manufacturers in India.
