Coal milling helps the energy-saving transformation of thermal power

With the rapid development of national energy conservation and environmental protection, the use of coal for thermal power generation has also begun to save energy, and clean coal combustion technology has become an important measure
to protect the environment, increase income and create efficiency.

It is understood that for a long time, the use of coal for thermal power generation has become the main way of various power plants, at present, China's coal-fired industrial boilers in use are mainly chain grates, the actual operation combustion efficiency, boiler thermal efficiency is lower than the international advanced level of about 15%, soot emissions account for about 44.
8% of the total national emissions, carbon dioxide emissions account for about 10% of the total national emissions, sulfur dioxide emissions account for 36.
7%
of the total national emissions.
Under the pressure of environmental governance, the clean and efficient use of coal has become a top priority for the continued development of thermal power plants
.
In the future, coal for electricity will still be the focus of coal consumption, and the proportion of coal power will continue to increase, reaching 54.
74% in 2020, and China's coal demand will peak in 2020
.

The so-called coal pulverization is the use of mills and supporting equipment to prepare high-efficiency pulverized coal, the most common way of use is to supply industrial boilers for power generation, heating, steam supply and hot water, with significant economic and environmental benefits
.
It can be said that coal milling is a way
with significant economic and environmental benefits.

Taking the industrial boiler of thermal power plant as an example, the use of pulverized coal as fuel can reduce energy consumption and pollutant emissions: the burnout rate of pulverized coal boiler furnace is higher than 98%, the thermal efficiency of boiler operation is higher than 90%, and the energy saving is more than 30% than that of traditional boilers, and the soot ≤ is 30mg/m3, sulfur dioxide ≤ 100mg/m3, and nitrogen oxides ≤ 200mg/m3, which is lower than the national emission standard and meets the strict environmental protection requirements
of various places.

At present, with the release of the Action Plan for Energy Conservation and Emission Reduction Upgrading and Transformation of Coal Power (2014~2020), "Implement stricter energy efficiency and environmental protection standards, accelerate the upgrading and transformation of coal-fired power generation, and strive to achieve 'three reductions'
in power supply coal consumption, pollution emissions, and the proportion of coal in energy consumption.
" "It has become an important basis for the promotion of coal milling projects in thermal power plants, and pulverized coal boilers for thermal power generation have become a trend
