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 flue baffle for a water heater comprises a plurality of holes along a length of the baffle and a plurality of bent blades along the length of the baffle, where each hole of the plurality of holes is adjacent to a bent blade of the plurality of bent blades. The holes are configured to permit flue gas to pass through the holes. The bent blades can have an alternating pattern where a first bent blade extends from one side of the baffle and the next bent blade extends from an opposite side of the baffle. A press tool for forming the baffle comprises a piercing tool for forming the plurality of holes and a lance and fold die for forming the bent blades.

Devices, systems, and methods for carbon capture optimization in industrial facilities are disclosed herein. An example carbon capture process involves cooling a flue gas stream using at least one gas-to-air heat exchanger disposed upstream of a carbon dioxide (CO2) absorber. Another example carbon capture process involves heating a heat medium for solvent regeneration and CO2 stripping using a fired heater and/or using at least one waste heat recovery unit.

This invention provides a heat recovery and utilization system for efficiently utilizing heat recovered from boiler exhaust gas with a heat recovery unit without any complicated equipment or high operation costs. The heat recovery and utilization system includes: a boiler for electricity generation; a heat recovery unit for recovering heat from exhaust gas of the boiler; a heat exchanger for using heat recovered with the heat recovery unit as heat source for equipment other than for electricity generation; a heat accumulator for accumulating heat source for the equipment other than for electricity generation; and a heat medium circulation line in which heat medium circulates between the heat recovery unit and the heat exchanger to exchange the heat recovered with the heat recovery unit with the heat exchanger. Upon startup of the system, the heat exchanger preheats the heat recovery unit with heat source accumulated in the heat accumulator.

A system for reducing carbon dioxide emissions from a flue gas generated via combusting a fossil fuel is provided. The system includes a carbonator and a classifier. The carbonator is configured to receive the flue gas and carbon absorbing particles. The classifier is fluidly connected to the carbonator and configured to receive a mixture that includes heat-transferring particles and the carbon absorbing particles. The mixture is fluidized within the classifier via the flue gas at a velocity such that the flue gas entrains and transports the carbon absorbing particles to the carbonator while the heat-transferring particles are not entrained nor transported to the carbonator.
