Based on lots of experiments in tube furnaces, the ZDM series of additives for catalytic clean coal combustion are developed. By industrial experiments in large-scale chain grate boilers, it is shown that both the sulfur and nitrogen removal efficiencies in a furnace can achieve about 40%. When some additives are blended with the coal and the rest is injected into the combustion gas, which is called a two-stage desulfurizaiton technology, the sulfur removal efficiency can be greatly promoted to about 75%.

Based on lots of experiments in tube furnaces, the ZDM series of additives for catalytic clean coal combustion are developed. By industrial experiments in large-scale chain grate boilers, it is shown that both the sulfur and nitrogen removal efficiencies in a furnace can achieve about 40%. When some additives are blended with the coal and the rest is injected into the combustion gas, which is called a two-stage desulfurizaiton technology, the sulfur removal efficiency can be greatly promoted to about 75%. After the combustion procedure in a furnace and flue gas humidification in a water-film dust catcher, the desulfurization efficiencies of a blending additives process or a two-stage desulfurization process can reach about 60% and 90% respectively. The additives also have some catalytic on effects combustion and the boiler efficiency increases by 3%~5%. The dynamic characteristics of flue gas compositions are measured. It is found that the dynamic concentration peaks and valley of SO2 are opposite to those of O2. The change of NO concentration is similar to that of SO2, but in the mean time it is also affected by CO concentration.
