Coal

We expect coal demand to decline 5% in 2020 as lower electricity consumption (-1.5%) impacts demand for coal in a disproportionate way becausenuclear and renewable sources have largely priority dispatch in the electricity system. In addition, cement and steel production were depressed due to the confinements and economic slowdown.

Introduction to Boiler Scales

In general, the losses taking place on account of scales and deposit formation can be summarized as follows : 1. Excess amount of fuel required to convert same amount of water into the steam (decreased heat transfer). 2. Corrosion of copper alloy based heat exchanger tubes 3. Excess wall temperatures which can eventually result in tube failures.

Coal in Russia

Coal consumption. Russia is self-sufficient in coal, and consumed 223 million tons of coal in 2009. The percentage of coal in Russian power generation has been declining since 1990, when it was 20.7%, due to increasing gas consumption as well as increasing nuclear and hydroelectric energy production. Currently only 14.4% of Russia's power is produced from coal.

Scaling in boilers

Scaling in boilers Boiler scale is caused by impurities being precipitated out of the water directly on heat transfer surfaces or by suspended matter in water settling out on the metal and becoming hard and adherent. Evaporation in a boiler causes impurities to concentrate. This interferes with heat transfers and may cause hot spots.

How much do ultra

28.06.2017If the plant uses ultra-supercritical technology, it needs thermal input of 1000 MW / 44 per cent = 2270 MW-thermal. As a result, it burns 350 tonnes of coal per hour, or 14 per cent less than the subcritical plant and generates 14 per cent less SO2. If the plant is not equipped with SO2 emission control technology, that's the end of the story.
