AMERICAN SOCIETY OF MECHANICAL ENGINEERS PERFORMANCE TEST CODE 34 - ASME PTC 34 'Waste Combustors with Energy Recovery' What is PTC 34 and How Can it Help You?

摘要

ASME PTC 34 is a test procedure for determining the thermal capacity and thermal efficiency of systems (typically boilers) combusting waste fuels (typically Municipal Solid Waste - MSW) and for determining the higher heating value (HHV) of those waste fuels. The basis of the procedure is more commonly known as the "boiler-as-a-calorimeter" method. The need for PTC 34 arose from the difficulties in obtaining representative samples and accurate fuel analyses using traditional laboratory methods such as a "bomb calorimeter". Unsuccessful attempts were made to come up with a larger "bomb calorimeter", so a committee was formed to create PTC 34 which was published in 2007. ASME PTC 34 is firmly based on the widely accepted boiler test code, ASME PTC 4 - "Fired Steam Generators", but has several different challenges in having to measure the relatively difficult parameters of flue gas flow and moisture and fuel and ash quantities. As a result, the uncertainty of PTC 34 is higher. However, the philosophy of correcting results to standard, contract or reference fuel analysis is the same in PTC 4 and PTC 34. So, an industry approved Code for acceptance testing is available to the Energy-from-Waste industry.
