The results showed that, the power plant which burn medium and high ash content coal and medium and high sulfur content coal can reach the ultra-low emission standard by selecting appropriate technical routes. This paper also give advice on the choices of ultra-low emission technical routes for coal-fired power plants which burn medium and high ash content and medium and high sulfur content coal.
