Mechanical Fossil Ash Kiln Manufacturer: Characteristics of Energy Saving Lime Kilns
Mechanical fossil ash kiln manufacturers believe that there are two aspects to energy consumption in lime kilns: thermal energy consumption and electrical energy consumption. Therefore, the safety of the lifting belt is very important. Therefore, current research and production units take these two points as the starting point to develop energy-saving technologies and measures for lime kilns. By technological transformation of the lime rotary kiln, the goal of energy conservation and consumption reduction has been achieved. The specific directions can be summarized as new calcination technology, kiln lining coating technology and new kiln lining structure development, kiln waste heat utilization technology, automation and energy-saving technology, and so on.

Mechanical fossil ash kiln manufacturers believe that oxygen rich combustion technology is a promising, energy-saving, and environmentally friendly combustion method in industrial furnaces and kilns. Through theoretical analysis and research on this technology, combined with production practice, a new oxygen rich burner structure and control method have been proposed. It has been successfully applied in glass furnaces, non-ferrous metallurgy and many other industries and fields, and has a wide range of applications. The use of oxygen rich furnace combustion technology in cold regions of northern China is of great significance for changing the production environment and saving energy.
On the one hand, oxygen rich combustion can reduce the demand for air and reduce the amount of flue gas generated. The utility model reduces the loss of heat carried away by the flue gas and increases the heat utilization rate; At the same time, some waste gas can be converted into high-grade thermal energy for preheating air, improving the thermal efficiency of the kiln. On the other hand, it can increase the theoretical heating temperature and theoretical combustion temperature, which is conducive to sufficient fuel combustion. Improving combustion efficiency through oxygen enrichment is currently one of the more effective energy-saving methods, and it can achieve no redox reaction, thereby achieving cost savings. The oxygen rich combustion technology can also improve the theoretical combustion speed, increase the radiation heating coefficient, widen the ignition limit, and reduce the excess air coefficient. In addition, enriched oxygen can make the airflow distribution in the furnace more uniform, thereby reducing the flame size, improving the distribution of flue gas temperature at the furnace outlet, and improving thermal efficiency. In summary, the application of oxygen rich combustion technology in industrial furnaces has enormous technological advantages, which is of great significance for energy conservation and consumption reduction in industrial furnaces. Through experimental research and numerical simulation, the significant effect of enriched oxygen on energy-saving of industrial furnaces has been verified. For large metallurgical enterprises with excess oxygen, the use of oxygen rich combustion technology in metallurgical lime kilns can effectively save energy and reduce consumption.
Mechanical fossil ash kiln manufacturers believe that during lime calcination, limestone decomposition not only absorbs sufficient decomposition heat, but also ensures an appropriate calcination temperature to quickly decompose limestone. Lime kilns use fuels with high calorific value, which can meet the requirement of rapid decomposition of lime when the combustion temperature is high. Under the condition of using low calorific value fuel in the lime kiln, measures should be taken to strengthen combustion, increase the calcination temperature, and ensure the rapid decomposition of limestone.
Mechanical fossil ash kiln manufacturers believe that using insulation technology in the kiln is an important means to reduce heat loss in the furnace body. This article introduces a new type of insulation method - the new technology of spraying insulation layer on the surface of the kiln body. The technical key lies in reducing the comprehensive heat transfer coefficient between high-temperature materials and gases in the kiln through the kiln lining, mainly determined by the convective radiation heat transfer inside the kiln, and the thermal conductivity of the kiln lining and the convective radiation heat transfer of the kiln outer wall. Due to the use of refractory bricks or other insulation materials on the kiln body for insulation, the temperature distribution inside the kiln can be uniform and consistent, thereby improving the furnace temperature level and output, and saving energy.
