Abstract: Delivery mechanisms and distribution mechanisms are varied, adjusted, or modified based on a desired fuel application. Dimensions, flow rates, pressures, viscosities, temperatures, friction parameters, and combinations thereof may be varied, adjusted or modified. The fuel application may include a scrubber application. The scrubber application uses a delivery mechanism to deliver a wet or dry scrubbing agent at a low pressure to a distribution mechanism. The distribution mechanism distributes the scrubbing agent within the scrubbing chamber. The delivery mechanism is adjustable based on properties of a feedstock utilized to deliver the scrubbing agent, properties of a propellant, or properties of the scrubbing application. The distribution mechanism is adjustable based on desired distribution characteristics including shape, size, or velocity of drops, mists, or particles distributed.

Abstract: Particulate-containing hot flue gas flows are flowed into a boiler having a first and a second chamber. The first chamber has a gas side and a water side. The hot flue gas flows into the gas side of the first chamber which is in heat exchange relation with the water side. Steam is generated on the water side and transported to a power generator. Steam or another inert gas is periodically injected into the gas side of the first chamber for removing particulate fouling when the heat exchange relation for the gas side falls below a predetermined minimum level. Cooled flue gas leaving the gas side of the boiler is conducted to a purification chamber having spray nozzles thereby allowing large particulate to settle out of the flue gas and removing fine particulate entrained in the flue gas enabling purified flue gas to be released from an upper portion of the second chamber.
