Abstract In order to improve the high temperature melting characteristics of bituminous coal with low ash point, three kinds anthracites were used blended meet requirement blast furnace injection. The complete pulverized had been calculated by using FactSage thermodynamic calculation software. results showed that after adding different proportions anthracite deformation temperature, softening h...

Due to the abundant coal reserves in China, coal is expected to be the most important energy resource in the future. The ash deposition/slagging behavior can obviously affect the heat transfer efficiency of heat transfer tubes in boiler, and cause increasing coal consumption. In order to clarify the effect of ash deposition behavior on heat transfer characteristics of the tube in boiler, a pulv...

Purpose. To develop scientific foundations and technical solutions to implement the converting of anthracite boiler 800 MW unit Slovianska TPP with central coal pulverizing plant sub-bituminous combustion maximum use existing equipment, without stopping unit’s operation. Methodology. Theoretical calculational studies on processes drying at plant. Calculational justification eliminate risk pulve...

Currently, conversion of coal into alternative fuel and non-fuel valuable products is in demand growing interest. In the present study, humic acid was extracted from two different ranks coal, i.e., low rank high (lignite bituminous), through chemical pretreatment by nitric acid. Samples lignite bituminous were subjected to oxidation followed extraction using KOH NaOH gravimetric techniques. The...

Industries using conventional fossil fuels have an interest in better understanding the mechanism of particulate formation during combustion since such is responsible for emission of undesired inorganic elements that directly impact the atmospheric pollution level. Fine and ultrafine particulates have tendency to escape the flue gas cleaning devices to the atmosphere. They also preferentially c...

The Clean Coal Technology (CCT) Demonstration Program is a government and industry co-funded effort to demonstrate a new generation of innovative coal utilization processes in a series of " showcase " facilities built across the country. These projects are carried out on a scale sufficiently large to demonstrate commercial worthiness and to generate data for design, construction, operation, and...

This work describes the use of intermediate pyrolysis system to produce liquid, gaseous and solid fuels from pelletised wood and barley straw feedstock. Experiments were conducted in a pilot-scale system and all products were collected and analysed. The liquid products were separated into an aqueous phase and an organic phase (pyrolysis oil) under gravity. The oil yields were 34.1 wt.% and 12.0...
