In a high-efficient clean, high-variable load rate coal-fired power generation system, through the internal thermal source SCR denitration catalytic module coupled with high temperature and low temperature storage tanks, the operating temperature of the internal thermal source SCR denitration catalytic module is controlled in a range of 300° C. to 400° C., ensuring that the SCR catalyst has high activity in full-working conditions. Moreover, the high temperature and low temperature storage tanks are coupled with the high-pressure heater group for steam turbine regenerative system, so that when the coal-fired unit needs to increase load rate, the thermal storage energy is quickly converted into output power. In addition, energy stored in the high temperature and low temperature storage tanks come from both the internal thermal source SCR denitration catalytic module and the thermal storage medium heater within the boiler, the operational flexibility and the boiler efficiency are improved.

A heat exchange apparatus for removing magnetic particulates from a gas stream, including a rotating element basket having a regenerative heat exchanger and at least one magnetic element. A method of removing magnetic particulates from a gas stream, including heating the regenerative heat exchanger during a first portion of a cycle as a segment of the rotating element basket passes through a first zone wherein contact is made with a flue gas thereby accumulating any magnetic particulates as they are attached to the magnetic element. Then cleaning a portion of the magnetic element during a second portion of the cycle. And cooling the regenerative heat exchanger and simultaneously heating an inlet air stream during a third portion of the cycle as the segment of the rotating element basket passes through a third zone wherein fluidic contact is made with the air inlet stream.

An apparatus capable of monitoring and adjusting an in-furnace combustion condition in real time, having: a furnace having a heating chamber, a combustor, a charging door, an exhaust gas flow port, and an exhaust gas flow pipe, wherein the combustor is used for introducing fuel and/or an oxygen-containing gas into the heating chamber to form a flame, the charging door is used for adding a raw material, and the gas generated by combustion in the heating chamber enters the exhaust gas flow pipe through the exhaust gas flow port; two sensors of the same type arranged at different positions in the exhaust gas flow pipe; and a control device receiving signals of the two sensors and adjusting, according to a difference between the signals, the amount of the fuel and/or the oxygen-containing gas entering the combustor.

A system for treating exhaust gas generated by combustion of biomass comprises a frame, a first cyclonic separation stage supported on the frame and comprising a plurality of parallel gas cyclones in fluidic communication with an inlet receiving the exhaust gas for removing from the exhaust gas particulate matter exceeding a first threshold size, and a second bag filtration stage supported on the frame and comprising a plurality of serially-communicated baghouses each comprising a plurality of bag filters therein for removing, from the partially treated exhaust gas received from the first cyclonic separation stage, particulate matter exceeding a second threshold size that is smaller than the first size which was passed through the first treatment stage. The gas cyclones of the first stage are arranged in a laterally extending row across the frame and the baghouses are arranged in a longitudinally extending row across the frame.
