One of the key factors in providing a crisis-resistant form of performing laboratory classes in universities in distance mode is educational computer programs in the form of virtual laboratory works. Such software provides students to get proper practical experience working with technological equipment in absence of direct contact with the teacher and real laboratory units. They are also an alternative to real physical laboratory units and can be used by students in event of physical wear and tear of laboratory equipment or its complete absence. The article presents an educational computer program designed for laboratory works on five virtual laboratory units to the discipline “Heat supply of forest enterprises” for students to master materials on the following topics: “Determination of fuel humidity”; “Determination of the yield of volatile substances and coke”; “Determination of fuel ash content”; “Determination of the heat of combustion of solid fuel”; “Analysis of flue gases”. The authors showed the principle of performing all virtual laboratory works on the example of one laboratory work, identified the advantages of presented computer program and indicated high significance and efficiency of its use. The developed program is successfully used by students of Reshetnev Siberian State University of Science and Technology, allows you to hold laboratory works in distance mode and reduce the time for their implementation by accelerating the simulated processes.
