The report gives results of a review of available data on emission factors for major categories of direct-fired heaters. Systematic studies were analyzed to develop emission factors for oxides of nitrogen (NOx) at various levels of combustion air preheat used in major energy-consuming industries. Industrial fuel use in non-boiler applications amounted to about 60% of total industrial fuel consumption in 1980. Historically, air pollution control of these sources has focused on emissions of NOx. NOx, however, currently are felt to play a role in the formation of acid precipitation. The increasing use and potential for use of preheated combustion air for energy conservation may result in increased emissions of NOx from direct-fired process heaters. Limited data show that NOx emission rates rise as combustion air temperature increases. Studies indicate that a significant market for high temperature heat recovery equipment for use with many types of industrial sources will exist as they become proven and are applied to both new and existing sources. If these devices, which can preheat combustion air to 1093-plus C, are applied extensively, nationwide emissions of NOx could increase significantly.
