Review of coal-water fuel pulverization technology and atomization quality registration methods

Possibilities of coal-water fuel application in industrial power engineering are considered and described. Two main problems and disadvantages of this fuel type are suggested. The paper presents information about liquid fuel atomization technologies and provides data on nozzle type for coal-water fuel pulverization. This article also mentions some of the existing technologies for coal-water slurry spraying quality determination

Implementation of Federal Research Projects as a Tool to Enhance the Training Quality of Master's Program

Analytical study of the impact of Federal target programs (FTP) implementation with involvement of master's program students for the purpose of obtaining practical skills, identifying and developing organizational skills, increasing motivation to the educational process and competitiveness in the labor market. The result of a parallel implementation of the Federal program and training of students in the master's program has significantly improved the performance of students. The average point increased from 4.23 in 2014 to 4.55 in 2015. The publication activity increased by 64%, the number of conferences with participation of students in the master's program increased by 75%. The growth of these criteria is caused by a large number of experiments carried out, analytical review, the practical relevance of the studied material and level of motivation due to payments to students from the Federal program funds

Research of Heating Rates Influence on Layer Coal Gasification of Krasnogorsky And Borodinsky Coal Deposit

Experimental research of heating rate influence on coal samples gasification process of Krasnogorsky and Borodinsky coal deposit ranks A and 2B was done to define optimal heating mode in high intensification of dispersal of inflammable gases conditions. Abundance ratio of carbon monoxide and nitrogen monoxide, water vapor, carbon dioxide at four values of heating rate within the range of 5 to 30 K/min. with further definition of optimal heating rate of coals was stated

Influence of NaNA[3] and CuSO[4] catalytic additives on coal oxidation process kinetic dependencies

Experimental studies of bituminous coal and lignite oxidation were conducted with the addition of different nature catalytic additives: NaNO[3] and CuSO[4]. The results showed that added mineral salts led to a noticeable decrease in the coals initial oxidation temperature and reaction acceleration at an early stage of the process

Assessment of Efficiency of Regenerative Heating System of Feed Water for High Temperature Turbine Plant on Decentralized Power Engineering Facilities

The results of theoretical researches on efficiency of air heater use have been presented. The results of the research show the possibility of increase of energy efficiency of electrical power unit on electrical energy consumption by 2% at the initial temperature of steam 1073 K. The possibility of decrease of unit consumption of reference fuel by 4% has been stated

Research of rheological properties improvement methods of coal-water fuel based on low-grade coal

Experimental studies of coal-water fuel (CWF) rheological properties based on 3B brown coal have been conducted using different processing methods, such as rotary flows modulation device (RFMD), sodium hydroxide and lignosulfonate. Physicochemical properties of initial solid fuel have been determined using JEOL JCM 6000 microscope. Optimal method of coal-water treatment has been determined based on obtained data considering its influence on viscosity and sedimentation stability of coal-water slurry (CWS)

Increase of Engineering Students Training Level

The article considers the problem of the widespread introduction of computer technology in the training of students in technical areas. This leads to a significant deterioration in the quality of practical training. Implementation in the educational process of the laboratory complex, which represents a real model of the power plant, has led to improved academic achievement in core subject areas. This equipment allowed the students to gain practical skills for different types of works with the equipment on the basis of the University, and also helped to increase the interest of students in carrying out the laboratory and practical work
