How to Reduce Heat Loss with Active Lime Rotary Kiln

Introduction: With the government's awareness of environmental protection greatly enhanced, many companies are now focusing on energy conservation and environmental protection. When a business purchases a rotary kiln, it not only hopes to bring huge benefits to the company's production, but also requires energy conservation and environmental protection in the production process, and hopes to minimize environmental pollution and damage.

At present, rotary kiln is widely used in metallurgy, building materials, chemical, refractory, ceramic, papermaking and other industries. So, how can the active lime rotary kiln reduce the heat loss and allow the equipment to achieve low energy consumption? Take Zheng's mine machine as an example, the measures to reduce energy consumption are as follows:

1. The vertical preheater is arranged in the kiln to make full use of the high-temperature flue gas produced in the rotary kiln to preheat the limestone from the normal temperature to the initial decomposition state so as to reuse the heat and reduce the heat loss.

2. Make a new change in the structure of the furnace and greatly improve its heat transfer efficiency and decomposition rate.

3, increase the efficient heat exchanger to the system, the kiln sealing device to be modified to promote the air leakage coefficient has decreased.

4. The selection and design of refractories should be the best, so as to effectively reduce the temperature of the kiln shell surface.

5. Limestone uses crystal grains less than one millimeter. The limestone used is small and uniform in size, and the fuel must have high calorific value.
