TECHNICAL SPECIFICATION
Overview Steam coal, also known as thermal coal, is a type of coal used to generate steam in power plants, industrial processes, and other applications.
Characteristics
Steam coal typically has:
1. High calorific value: Energy content measured in British Thermal Units (BTUs).
2. Low moisture content: Affects coal's energy content and burning characteristics.
3. Moderate ash content: Affects coal's burning characteristics and environmental impact.
4. Low sulfur content: Affects coal's environmental impact and burning characteristics.
Uses
Steam coal is primarily used for:
1. Electricity generation: Coal-fired power plants.
2. Industrial processes: Cement production, paper mills, and other industries.
3. Domestic heating: Residential and commercial heating.
Types of Steam Coal
Common types of steam coal include:
1. Bituminous coal: Most common type of steam coal.
2. Sub-bituminous coal: Lower rank than bituminous coal.
3. Lignite coal: Lowest rank of coal, often used for electricity generation.
Production and Trade
Steam coal is produced and traded globally, with major producers including:
1. China: Largest producer and consumer of steam coal.
2. India: Second-largest consumer of steam coal.
3. Australia: Major exporter of steam coal.
4. Indonesia: Major exporter of steam coal.
Environmental Impact
Steam coal combustion releases green house gases and other pollutants, contributing to:
1. Climate change: Greenhouse gas emissions.
2. Air pollution: Particulate matter, sulfur dioxide, and nitrogen oxides.
3. Water pollution: Coal ash and waste water.
