Answer / Abhijit Kumar Sinha

To prevent backfire in a boiler, it's essential to maintain proper combustion efficiency. This can be achieved by adjusting the air-fuel ratio, using an adequate amount of primary and secondary air, maintaining clean burners, and ensuring regular inspection and maintenance of the boiler. Additionally, installing a safety device like a pressure relief valve or a backfire flame arrestor can also help prevent backfire.

In a boiler Natural gas flow 10,000 N cubic meter and combustion air flow 22,000 cubic meter, how I convert gas flow N cubic meter to cubic meter to maintain fuel air ratio? Thank you. ashekullah
