Description:
The paper discusses the application of pulse combustion to solid and hazardous waste incineration. otary kiln incinerator simulator was retrofitted with a frequency-tunable pulse combustor to enhance the efficiency of combustion. he pulse combustor excites pulsations in the kiln and increases the completeness of combustion by promoting better mixing within the system. ests were performed using toluene sorbed onto a ground corn cob sorbent and placed in cardboard containers. he burner was operated in a non-pulse mode as a baseline condition, and then in a pulse mode in which the frequency of the pulse combustor was adjusted to the natural frequency of the combustion chamber, creating resonant pulsations of large magnitude. he test was also performed using polyethylene tube bundles to simulate a solid waste and to investigate a surrogate which produces different puff characteristics. he addition of turbulence in the rotary kiln due to high amplitude acoustic pulsations has a strong tendency to reduce the amount of soot and/or semi-volatile and non-volatile hydrocarbons. ass emissions of soot were consistently reduced in all tests. arbon monoxide increased during acoustic pulsations in the toluene tests. he paper also discusses unsatisfied oxygen demand and carbon penetration and how pulsations affect them.
