Claim 15:
16. A system for removing one or more air pollutants from a gas stream of an industrial facility, the system comprising:
an industrial apparatus configured to produce a gas stream comprising a plurality of calcium-containing particles and one or more pollutants;
an injection system downstream of the industrial apparatus and configured to inject an injectate into the gas stream such that the injectate adsorbs to at least one of the calcium-containing particles or the one or more pollutants, the injectate comprising at least one of calcium hydroxide, calcium oxide, or powder activated carbon (PAC);
a baghouse downstream of the cooling apparatus and injection system, the baghouse being positioned to filter the calcium-containing particles from the gas stream;
a cooling apparatus between the baghouse and the industrial apparatus and positioned to receive at least a portion of the gas stream, wherein the cooling apparatus is configured to cool the gas stream;
a temperature sensor positioned downstream of the cooling apparatus and configured to measure a temperature of the cooled gas stream; and
a controller in communication with the temperature sensor and the cooling apparatus, wherein the controller is configured to cause the cooling apparatus to cool the gas stream, based on the measured temperature, to no less than 250° F.
