Summary of the subject: The basis of the course project is the verification calculation of steam boilers, which are serially produced by boiler-making factories and used in industrial thermal power plants. During the implementation of the course project, the student must familiarize himself with the design of the boiler unit in detail, perform a thermal calculation of all heating surfaces and depict the cross-section and longitudinal section of the boiler unit on the drawing.
Опис: Calculation of the boiler unit. Determining the coefficients of excess air along gas flues. The calculation of the volume of air and products of combustion. Calculation of enthalpy of air and products of combustion. The calculation of the heat balance of the boiler. The calculation of heating surfaces. The calculation of geometric dimensions of the furnace of boiler. The calculation of heat exchange in the firebox of boiler. The calculation of convective heating surfaces. The calculation of superheater. The calculation of water economizer. The calculation of air heater.
Assessment methods and criteria: Assessment of knowledge is provided by current (written component) and summative assessment. Current control involves the assessment of the following components: – the timeliness of the implementation of the course design work schedule; - modernity and justification of the decisions made; - correct application of analysis and calculation methods; - quality of design, compliance with the requirements of regulatory documents. The summative assessment involves the assessment of the following components: - degree of mastery of the material; - completeness of the analysis of possible options; - the degree of justification of the decisions made; - the ability to defend one's opinion.
Критерії оцінювання результатів навчання: - written component (30%): quality of calculations and explanatory notes; - summative assessment (70%, credit): defense of сoursework.
Порядок та критерії виставляння балів та оцінок: Points for current and exam control are assigned as a percentage of the maximum grade for the educational material of the component based on the following criteria for evaluating the student's knowledge and skills: 100–88% – awarded for a high level of knowledge; 87–80% – awarded for knowledge of the educational material of the component above the average level, including calculations, reasoned answers to the questions asked (a small amount of inaccuracies is possible); 79–71% – a generally correct understanding of the educational material of the component is presented, including calculations, reasoned answers to the questions, which, however, contain certain (insignificant) shortcomings; 70–61% – awarded for mediocre knowledge of the educational material of the component; 60–50% – awarded for weak knowledge of the educational material of the component; 49–26% – presented for ignorance of a significant part of the educational material of the component; 25–00% – awarded for not knowing a significant part of the educational material of the component. Current and control testing is carried out in the National Security Service and the grade is automatically assigned for all test tasks. The exam is conducted in written and oral form (the exam test is valued at 70 points, the oral component - 10 points). The oral examination involves a sample question from different sections of the course and the completion of simple tasks.
