Modern methods for reduction of air pollutants from boiler units

Description: The discipline studies the reduction of emissions of pollutants into the atmosphere from boilers by technological methods of organizing the combustion process, as well as by using dust collecting and gas cleaning equipment. It considers the development, current state and prospects for improving these technologies.

Goal

• To study ways to reduce emissions of pollutants into the atmosphere from boiler units by technological methods of organizing the combustion process, as well as by using dust-collecting and gas-cleaning equipment

Objective

• study the technological characteristics of thermal power plants in terms of air pollution, - consider restrictions on emissions of pollutants into the atmosphere from boiler plants, - to study technologies for preventing the formation of pollutant emissions from boiler plants, - to study technologies for cleaning flue gases from pollutants.

Learning outcome: knowledge and understanding

• Know the technological processes that take place in boiler plants and understand their impact on pollutant emissions.

Learning outcome: applying knowledge and understanding

• Be able to apply knowledge and understanding about boiler plants to analyze and develop technologies to reduce pollutant emissions.

Learning outcome: formation of judgments

• Have the ability to balance the facts of the formation of emissions from boiler plants and possible approaches to reduce them, taking into account technological, economic and environmental criteria.

Learning outcome: communicative abilities

• Be able to formulate, discuss and explain topical issues on technologies for reducing emissions from boilers.

Learning outcome: learning skills or learning abilities

• Have skills in boiler abatement technologies that are required to continue learning with a high degree of autonomy.

Teaching methods

In the conditions of credit technology of education, classes should be conducted mainly in active and creative forms. Among the effective pedagogical methods and technologies that contribute to the involvement of students in the search and management of knowledge, the acquisition of experience in independent problem solving, we should highlight: - technology of problem-based and project-based learning; - technologies of educational and research activities; - communication technologies (discussion, press conference, brainstorming, educational debates and other active forms and methods); - case method (situation analysis); - gaming technologies, within which students participate in business, role-playing, simulation games; - information and communication (including distance learning) technologies.

Assessment of the student's knowledge

Teacher oversees various tasks related to ongoing assessment and determines students' current performance twice during each academic period. Ratings 1 and 2 are formulated based on the outcomes of this ongoing assessment. The student's learning achievements are assessed using a 100-point scale, and the final grades P1 and P2 are calculated as the average of their ongoing performance evaluations. The teacher evaluates the student's work throughout the academic period in alignment with the assignment submission schedule for the discipline. The assessment system may incorporate a mix of written and oral, group and individual formats.

The evaluating policy of learning outcomes by work type

Evaluation form

The student's final grade in the course is calculated on a 100 point grading scale, it includes:

• 40% of the examination result;
• 60% of current control result.

The final grade is calculated by the formula:

 

Where Midterm 1, Midterm 2are digital equivalents of the grades of Midterm 1 and 2;

E is a digital equivalent of the exam grade.

Final alphabetical grade and its equivalent in points:

The letter grading system for students' academic achievements, corresponding to the numerical equivalent on a four-point scale:
