Abstract: A method and apparatus for controlling pollution and flue gases from a boiler using municipal solid waste as a fuel. The flue gases pass through internal and external economizers before entering a reactor in which the gases are treated with lime or other reactant in slurry form to neutralize the acid components of the flue gases. The heat of the flue gases dries the products of the reaction and the excess reactants so that they may be separated from the flue gas in subsequent separator, which is a baghouse filter. The feed of the reactant to the reactor is modified in accordance with the concentration of acid constituents in the flue gas, and concurrently the operation of the economizers is modified to raise the temperature of the flue gas exiting the economizers when the feed of reactant is increased and vice versa. The temperature of the flue gas is increased by causing the feed water to bypass the external economizer in direct relation to the quantity of reactant fed to the reactor.

Abstract: Exhaust gases from a process fired boiler are diverted from a stack prior to emission to the atmosphere through a duct system to a plurality of series connected heat exchangers. The exhaust gases are progressively reduced from an elevated temperature, for example in the range between about 350.degree.-525.degree. F., in stages to an ambient temperature of about 50.degree. F. At each stage heat from the exhaust gases is transferred from the gases to another medium, such as water, which is fed back to the boiler to reduce the energy cost of operating the boiler. At ambient temperature the exhaust gases are subjected to an atomized spray of a reagent solution that absorbs the contaminants in the exhaust gases. Absorption of the contaminants into solution with the atomized reagent spray is promoted by contact of the spray and exhaust gases on the surface of a fibrous batting.

The effluent removes moisture from the mixture of concentrated sludge and dehydrated particulate matter to provide dehydrated particulate sludge and the gaseous discharge. Entrained materials are initially separated from the gaseous discharge by cyclone separators.

A single thermocouple (throat TC) senses the instantaneous temperature in the throat of the furnace and in cooperation with a programmable controller, maintains a preselected ramp and soak temperature profile over the entire burn cycle. When the temperature required by the profile is exceeded, a single water spray actuated by a signal from the PC lowers the temperature below the profile. The throat TC thus maintains a fire under controlled temperature conditions in the main chamber without an explosion, using a single-stage system.
