Maximizing

摘要

In the past several years, natural gas cost for an East Coast plant has increased from a typical value of $2.50 per million BTU to $10 per million BTU. Because the thermal oxidizer incineration temperatures must remain constant, fuel costs for air pollution cleanup have increased proportionately. The plant has four thermal oxidizers operating at an incineration temperature of 1,500℉ (815℃). In the interest of energy conservation, the company asked one oxidizer maker to look into methods of reducing the fuel usage for these thermal oxidizers. A thorough study of the application showed that there were two ways to reduce oxidizer fuel use and still meet the air pollution control requirements: 1. Install a standard heat exchanger. 2. Install an auxiliary catalytic assembly.
