The present invention relates generally to the field of emission control equipment for boilers, heaters, kilns, or other flue gas-, or combustion gas-, generating devices (e.g., those located at power plants, processing plants, etc.) and, in particular to a new and useful method and apparatus for reducing and/or eliminating various liquid discharges from one or more emission control equipment devices (e.g., one or more wet flue gas desulfurization (WFGD) units). In another embodiment, the method and apparatus of the present invention is designed to reduce and/or eliminate the amount of liquid waste that is discharged from a WFGD unit by subjecting the WFGD liquid waste to one or more drying processes, one or more spray dryer (or spray dry) absorber processes, and/or one or more spray dryer (or spray dry) evaporation processes.

A fired heater includes a fired heater body with an air inlet and a flue gas outlet, and a flue gas waste heat recovery system communicated with the fired heater body and including at least two heat exchange chambers. A first port of each of the heat exchange chambers can be communicated with the flue gas outlet or the air inlet, and a second port of each of the heat exchange chambers can be communicated with the outside air or a fume extractor. When the first port of at least one heat exchanger chamber is communicated with the flue gas outlet and the second port thereof is communicated with the fume extractor, the first port of at least another heat exchange chamber is communicated with the air inlet and the second port thereof is communicated with the outside air.

The present technology describes various embodiments of systems and methods for handling emissions. More specifically, some embodiments are directed to systems and methods for collecting heated particulate from a coal processing system. In one embodiment, a method of handling emissions from a coal processing system includes inletting the emissions into a duct. The emissions include heated particulate. The method further includes slowing a speed of the emissions traveling through the duct and disengaging the heated particulate from the emissions without the use of a physical barrier. In some embodiments, the heated particulate is slowed, cooled, and diverted from an emissions pathway into a collection bin.

A heat-resistant body has a cavity for exhaust gas, which is open at opposite ends. The body has first wall portions, each of which delimits a first portion of the cavity. Each first wall portion has an outer region and an inner region which has planar protrusions which each extend from the outside region inward into the associated first cavity portion, the planar protrusions tapering along the longitudinal extent in their width directed perpendicularly to the longitudinal extent and being mutually laterally spaced. Each planar protrusion of a first wall portion is rotated or shifted relative to a planar protrusion of an adjacent first wall portion. The body has second wall portions, each of which delimits a second portion of the cavity and is disposed between two adjacent first wall portions. The cross-sectional area of each second cavity portion is larger than the cross-sectional area of each first cavity portion.

An exhaust duct and boiler can appropriately collect solid particles in flue gas by way of being provided with: a flue (40) in which flue gas can flow; a first hopper (61) that is provided in the flue (40) and that can collect solid particles (PA) in the flue gas; and a first baffle plate (71) and a second baffle plate (72) that are resisting members capable of blocking the flow of solid particles (PA) from the first hopper (61).

The present invention relates to an iron fuel boiler process for iron fuel combustion, comprising the steps of combusting an iron fuel suspension medium comprising iron fuel and oxygen in an iron fuel burner arrangement to obtain an iron oxide containing medium; receiving the iron oxide containing medium into an iron fuel boiler arrangement for transferring the iron oxide containing medium towards a separation unit disposed at the end of said iron fuel boiler arrangement; exchanging heat between the iron oxide containing medium and a boiler of the iron fuel boiler arrangement with a heat-exchange medium during the transfer of the iron oxide containing medium through said iron fuel boiler arrangement; and separating iron oxide from the oxide containing medium to obtain solid iron oxide particles and a gas flow. The process further comprising the step of cooling said iron oxide containing medium with a cooling medium during said transfer of the iron oxide containing medium through the iron fuel boiler arrangement such that a temperature of the iron oxide is achieved of below the sintering temperature of the particles at said separation unit.
