What is the Difference Between Direct and Indirect Fired

Maximum efficiency is obtained generally when a boiler is used at 65-75% of load. 1 When the load of the boiler falls below 50%, in order to burn all of the fuel, more excess air should be fed and this will increase heat losses. Therefore, a boiler load which is under 50% is not suitable in terms of efficiency. 3.
