Limestone Activity Test Study

Desulfurizers include CaC, CaO, Mg, and a composite desulfurizer. The desulfurization agent is used for production and the cost of the ductile cast pipe is calculated. As the desulfurization rate is increased, the melting period is shortened, the reject rate is reduced, and the amount of spheroidizing agent is reduced. The cost per ton can save about 97 yuan. Heat desulphurization agent is used for the desulfurization of molten iron outside the furnace, the desulphurization rate can reach above 75%, the temperature drop of the molten iron is small, there is no need to increase the equipment, the operation process is simple, the economic benefit is good, and it is easy to popularize and use. However, if the amount of Al:03 formed is too large, the alkalinity of the slag is reduced, and the desulfurization rate is also reduced.

Limestone activity test studies have shown that, in contrast to SV, limestone lime slurry Ca(OH) in the desulfurization tower is more reactive than lime Cao produced by dry desulfurization with addition of limestone in the furnace. In dry desulfurization, different limestones naturally differ in their reactivity with Yang2 due to their different composition. With thermogravimetric analysis, the reactivity of limestone can be directly tested to evaluate the quality of different limestones. Lime In power plant flue gas desulfurization systems, thermogravimetric technology is used to effectively analyze the composition of limestone or lime slurry and evaluate the quality of limestone. According to the results of the thermogravimetric analysis, the desulfurization tower's desulfurization status can be understood, and the testers can further improve and improve the desulfurization process and method. As a new analysis and diagnostic technology, thermogravity has a wide range of application prospects in power plants.

The application can study the combustion characteristics of the boiler burning coal, perform the conventional industrial analysis of coal, save time and manpower, and timely guide the boiler operation.
