ASME PTC 34

Abstract

The rules and instructions given in this Code apply to all waste combustor systems with energy recovery, but the Code cannot detail a test applicable to every variation in the design of waste combustor systems. In every case, a qualified engineer must study the particular facility and develop a test procedure that is in agreement with the intent, guiding principles, and required accuracy of this Code. Examples of systems considered at the time of preparation of this Code include rotary kilns, refractory and waterwall furnaces, rotary combustors, mechanical grates, semi-suspension and suspension burning, multiple-chamber solid hearth, and two-stage combustion systems. Portions of this Code may be used for waste combustors without energy recovery in the area of unburned combustibles in residue. Testing of accessory equipment shall be performed using the applicable Performance Test Code. Refer to Fig. 2-4-1 for a typical system boundary. Test methods of this Code apply to solid, liquid, or gaseous waste fuels. Instructions are given to determine the thermal capacity and thermal efficiency of waste combustor systems by applying the concept of using the boiler as a calorimeter. In addition, the HHV of the waste fuel can be determined by weighing the waste fuel that has been consumed during the test.
