Why are there so few desulfurization majors in electric power recruitment, less than coal transportation majors! Seek discussion and answer.

What is electricity? Power generation, transformation, transmission, distribution and electricity consumption. Of the five links, only the power generation part is related to sulfur. This does not include hydropower, nuclear power, geothermal energy, wind power, tidal energy and solar energy. Thermal power generation is generally desulfurization. But they generally have no desulfurization personnel themselves. Just buy professional desulfurization equipment or ask professional institutions to serve. Service outsourcing. Supplement: For example, I am the person in charge of a power plant, and environmental protection is too important. I can spend more money, ask better experts to design desulfurization for me, buy better equipment, and ask better engineering teams to install and debug me. Generally speaking, desulfurization is a bit once and for all, and there is no need to send people to our company and factory for a long time. So all the services are outsourced.
