Thermal Performance of Biomass-Fired Steam Power Plant - ASME

6.6.1 Efficiency. Boiler efficiency can be calculated using ASME Performance Test Codes (PTC). PTC 34 is used for waste combustors with energy recovery using the boiler as a calorimeter. Using this method, the heat outputs, losses and credits must be calculated. Heat credits correct the efficiency to standard ambient conditions, such as air temperature.

Making Boilers More Efficient - ASME

Sep 18, 2012. by Nancy Giges ASME.org. In the boiler world, most upgrades over the years have been small innovative steps rather than anything highly revolutionary as the industry continues to improve safety and efficiency and to control emissions. Today, efficiency is the name of the game, and recently, companies have been focusing on changing the way the burner operates on the boiler as an important way to gain greater efficiency.
