What adjustments can be made to increase heat transfer efficiency in a boiler?

Several adjustments can be made to increase heat transfer efficiency in a boiler. The primary goal is to maximize the amount of heat transferred from the combustion gases to the water or steam in the boiler tubes. First, minimizing fouling and scaling on heat transfer surfaces is crucial. Fouling and scaling act as insulation, reducing heat transfer. Regular cleaning of the boiler tubes using sootblowers or chemical cleaning removes these deposits and improves heat transfer. Second, optimizing combustion conditions enhances heat release and improves he....
