The US-5000 Stack Emissions Monitoring System has a major design limitation of a maximum inlet temperature of 300F. In order to use the monitor, a sampling system was designed that has incorporated into it a heat exchanger which will reduce the temperature of the sampled gas from 700F to below 300F. The report includes a literature survey of the current state of the art in air pollution pollution monitoring. Basic heat transfer relations are discussed. The determination andor calculation of various constants needed in the design, such as thermal conductivity, velocity of the sample, and the mass flow rate of the sample are illustrated. Design calculations are carried out, and the heat exchanger specifications, i.e., number of tube banks, length, width, size, etc. are given. Proper sampling techniques are reviewed and the design is carried out with emphasis placed on accuracy as well as methods of removal of particulate matter from the gas.
