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.

Pre-commissioning operations of the boiler – hydraulic test, tinning and acid washing, steam test and adjustment 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 circuits and the boiler for ignition. Filling the boiler with water, ventilating the furnace and gas ducts.
Characteristics of drum boilers: temperature, thermal and economical when changing the following parameters: coefficient of excess air in the furnace; boiler load; feed water and air temperatures; moisture and ash content of fuel; sucked cold air into the furnace.
General provisions of the start-up modes of thermal power facilities: deaerator, feed pump; thermal station; hot water and steam supply pipelines; thermal energy consumers. The economy of their work.
Optimization of operating modes of thermal power facilities. Improvement of thermal schemes.
Assessment methods and criteria: Current monitoring of practical classes is carried out in order to identify the student's readiness for classes in the following forms:
• oral survey before the start of classes;
• assessment of the student's activity in the course of classes, submitted proposals, original solutions, clarifications and definitions, additions to previous answers, etc.;
• surveys and reports during the practical session.
Examination control is carried out in the form of a written and oral survey and/or test control.
The final control is carried out based on the results of the current control and semester examination control.
