Nowadays, the zero liquid discharge of flue gas desulfurization (FGD) wastewater from coal-fired units has attracted attention all countries in world. The pretreatment methods generally have problems high operation cost, small treatment capacity, and poor flexibility. However, membrane method can avoid above problems. In current research, it not been found that someone directly uses submerged u...

Air pollution control devices (APCDs) are installed at coal-fired power plants for air pollutant regulation. Selective catalytic reduction (SCR) and wet flue gas desulfurization (FGD) systems have the co-benefits of air pollutant and mercury removal. Configuration and operational conditions of APCDs and mercury speciation affect mercury removal efficiently at coal-fired utilities. The Ontario H...

Air and water pollution control programs sometimes result in production of solid wastes that are difficult to manage. The sludges from sewage treatment plants and flue gas scrubbers are two examples. In many coastal communities, there is no alternative to ocean dumpling of sewage sludges for the foreseeable future. The use of sludges as soil conditioners, their conversion to fuels by pyrolysis,...

Because ships burn inferior fuel, the emission of ship exhaust gas has a great impact on environment. In order to effectively deal with increasingly strict limit sulfur content and SO 2 fuel by International Maritime Organization. On basis analyzing characteristics soluble in seawater, this paper studies compares current industrial seawater desulphurization technology other flue desulfurization...

A set of pragmatic experimental investigations were initially undertaken using three straight flues attached to glass doored solid fuel appliances. Each system was built to satisfy existing regulatory requirements and instrumented with type K thermocouples at fixed locations within each flue. The fire gas temperatures were analysed for periods of steady state operation. It was concluded that ex...
