Water used in power plants is mainly used for cooling units and dissipating heat. Water is used as a means of cooling and its consumption is directly related to its method of heat exchange. Water cooling methods include direct heat dissipation through cooling towers and heat. dissipation by radiators, etc. Direct heat dissipation by cooling towers is closely related to It consumes a lot of money related to climate, wind, etc., while enclosed heat dissipation consumes almost nothing.
It depends on the amount of energy generated. Coal consumption is generally calculated based on an hour of use of 5,500 hours. In this case, a 1 million kilowatt thermal power plant uses approximately 1.5 to 1.8 million tons of standard coal per year. Standard coal refers to charbwe have a low calorific value of 7,000 kcal/kg.
We can only give a rough range of coal consumption here, as the efficiency of production units varies considerably. If it is an ultra-supercritical unit, it will consume less coal, while a subcritical unit will consume more. coal.
