Researchers from the Dehradun-based Indian Institute of Petroleumhave developed a new technologyfor multi-fuel burner for furnacescapable of saving 15 to 25 per centenergy over the existing burners.This is based on a new conceptcalled low air pressure (LAP) filmburner and can use more than twofuels simultaneously, that is, eitherfuel oil or natural gas or both. Theearlier designs of LAP burners weredependent on the quantity of combustion air, and any reduction in aircould affect its performanceadversely. Multi-fuel burners wouldbe of immense use to industrieslocated near gas fields because, attimes when natural gas is not sufficiently available, liquid fuel can supplement the storage of gas. Further,these types of burners do not needcleaning of fuel oil nozzle even aftercontinuous operation for weeks.
