Particulate Control

The commercial operation of coal-fired pressurized fluid-bed combustion-gas turbine plants for central station electric power generation or for industrial cogeneration applications depends on the reliable operation of the gas turbine. Reliable operation of the turbine is related to the particulate and chemical composition of the gases that it expands. This study is limited to an evaluation of particulates as they limit turbine life by erosion. Pressurized fluid-bed combustor design and operation trade-offs exist that affect the particle concentration and size ranges presented to the gas cleaning equipment. Gas cleaning equipment choices will subsequently effect the particulates going to the turbine. The development of a particle profile model permits an assessment of the effect of these decisions on the particles that enter the turbine. Turbine tolerance models previously developed by Westinghouse are then used to estimate turbine life and the incremental energy cost penalty. The scope of the evaluation procedure is presented and selected parametric cases presented to illustrate available trade-offs for design, operation, and cost.

The problem of air pollution with environmentally hazardous dust with a particle size of up to 10 microns at plants for the production of thermal insulation materials is considered. The purpose of this work is to study the dispersed composition of dust in the production of insulation materials (such as mineral wool), and to determine the effectiveness of the existing gas cleaning equipment, which traps pollutants. The dispersed composition of the dust generated at the plant for the production of thermal insulation materials, and the dispersed composition of the dust collected by the dust-cleaning equipment was investigated. Experimentally and with the use of computer programs, it has been established that the efficiency of extracting fine dust from dust- cleaning equipment does not exceed 78%. It is established that the dust of mineral wool entering the aspiration system is dominated by particles with a size from 2.5 microns to 25 microns. Dust with a SiO2 content of up to 70%, which is released during unloading and transportation of raw materials (dolomite, basalt), enters the atmospheric air without purification. At the same time, particles with a size of up to 60 microns and up to 72 microns dominate in atmospheric air, respectively. The main characteristics of the dust necessary for the objective selection of dust-cleaning equipment are determined.

Reduce Emissions

As a result, the implementation of measures to protect the atmosphere (the use of innovative technologies in the introduction of dust and gas cleaning equipment, the conversion of cars to gaseous fuel, the renewal of rolling stock, the implementation of the state program to reduce emissions), the stabilization of the environment is observed. It is necessary to carry out technical re-equipment of key sectors of the economy, the introduction of new technologies, as well as the stabilization and reduction of emissions of pollutants into the atmosphere. It is recommended to take additional measures to ensure that the amount of pollutants released into the atmosphere as a result of the operation of the facility does not exceed the permissible level, to install dust-collecting equipment that captures dust with high efficiency (up to 99.5%).
