1. Quicklime, also known as burnt lime, is mainly composed of calcium oxide. It is usually produced by calcining natural rocks, mainly composed of calcium carbonate, at high temperatures, which decomposes to produce carbon dioxide and calcium oxide (chemical formula: CaO, i.e., quicklime, also known as marble). Any natural rocks with calcium carbonate as the main component, such as limestone, chalk, and dolomitic limestone, can be used to produce lime. In coastal areas, seashells are used as raw materials, and are burned to produce shell ash, which is used as quicklime.
2. Fuel Selection and Characteristics of Rotary Kilns for Lime Calcination:
- Commonly used fuels in China include: Natural gas 、 Converter gas 、 Coke oven gas 、 Blast furnace gas and coal powder, etc. Commonly used fuels abroad include: Natural gas 、 Coal powder 、 Diesel and heavy oil, etc. In some areas, gas generators can also be used.
- Based on the characteristics of the above fuels, Zhengzhou Zhongwei Environmental Protection Equipment Co., Ltd. adopts the principle of "one kiln, one design" to design single-fuel or multi-fuel mixed-burning multi-channel rotary kiln burners, mainly to reduce users' fuel operating costs.
- Characteristics of Multi-channel Rotary Kiln Burner Equipment:
- The fuel and combustion air are fully mixed, the combustion is complete, and the energy-saving effect is significant.
- The length and thickness of the flame can be adjusted online. The flame combustion is vigorous, the calcination zone is long, the material calcination temperature is uniform, and the calcination quality is high.
- The rotary kiln burner is designed with various safety interlock functions. The PLC control cabinet reserves a remote port, which can realize on-site remote control functions.
For overseas market users, Zhengzhou Zhongwei Environmental Protection Equipment Co., Ltd. undertakes the EPC general contracting project of lime kilns, responsible for: rotary kiln burner combustion control system, kiln body refractory materials 、 Fuel and coal powder pipeline construction services.
