In this paper, an improved system to efficiently utilize the low-temperature waste heat from the flue gas of coal-fired power plants is proposed based on heat cascade theory. The essence of the proposed system is that the waste heat of exhausted flue gas is not only used to preheat air for assisting coal combustion as usual but also to heat up feedwater and for low-pressure steam extraction. Ai...

The addition of mist to a flow of steam or gas offers enhanced cooling for many applications, including cooling of gas turbine blades. The enhancement mechanisms include effects of mixing of mist with the gas phase and effects of evaporation of the droplets. An impinging mist flow is attractive for study because the impact velocity is relatively high and predictable. Water droplets, less than 1...

To address a decarbonized cement production process (DCPP), calcium looping is connected to an industrial (CPP) for capturing CO2 by 93.5~96%. Since the captured purity up 99.9 wt%, carbon capture and utilization (CCU) generate additional products of urea methanol. An integration DCPP CCU, named DCPP-based polygeneration system, being developed three scenarios. meet power demand producing high-...

Shortand long-term ground deformation at the cyclic steam stimulation (CSS) enhanced oil recovery sites in the Cold Lake region of Alberta, Canada, was measured with RADARSAT-2 differential interferometric synthetic aperture radar (DInSAR) during 2011–2016. The interferometric processing of 84 highresolution spotlight images revealed extensive short-term ground uplift and subsidence greater tha...

Computational techniques are used to optimize the design of an integrated energy park consisting of a coal-fired power plant, a CO2 capture system, and an auxiliary natural gas combined cycle plant. Emphasis is placed on the design of heat integration in the combined cycle system, as this heat constitutes most of the energy required for temperature-swing CO2 capture. The facility is constrained...

The techno-economic aspects of coal drying with cost effective waste heat recovery mechanism is one of the challenging issues faced while using lignite or high ash brown coal for direct combustion in coal fired thermal power plant. Coal being hygroscopic in nature, re-adsorbs considerable moisture even after conventional drying post wet coal washing condition affecting boiler performance. Parti...
