Modes of normal operation of equipment for storage, supply and preparation for burning solid, liquid and gaseous fuel. Water treatment. Modes of operation of chemical water treatment equipment and water supply pipelines (corrosion, degassing, water quality control). Water regime of steam and water heating boilers. Thermal deaeration. Operation of the deaerator installation. Switching on, servicing and stopping the deaerator installation. Malfunctions in the operation of the deaerator. Operation of the feeding unit and the feeding pump. Design features of feeding pumps. Start, service and stop of feed pumps. Modes of normal operation of boiler water supply schemes (deaerator-feed pump-boiler). Violation of normal work modes. Condensing unit. Purpose and brief description of the installation. Structure of capacitors. Condensate and circulation pumps. Ejectors. Start and stop of the condensing unit. Vacuum depth and problems in the operation of the condensing unit. Condensate quality. Regenerative installation. Schematic diagram. Structure and connection diagram of heaters. Thermal balance and operating modes of heaters. Maintenance of heaters. Evaporators. Operation of fittings. Pre-commissioning operations of the boiler – hydraulic test, tinning and acid washing, steam test and regulation of safety valves. Comprehensive testing of the entire steam power plant. Start-up schemes and start-up technologies of drum boilers. Preparation of start-up schemes and the boiler for ignition. Filling the boiler with water, ventilating the furnace and gas ducts.
