Lime: Hubei TX Project Project

Background:

Hubei TX Company has built two Φ4.5×64m active lime production lines with a designed capacity of 800t/d. The SR2-11Y/25YS low nitrogen burner independently developed by Xiangyang Zhonghe M&E Technology Co., Ltd. is used to quickly reach the production standard from ignition and drying kiln to formal production in only 7 days, and the production capacity, energy consumption and environmental protection indicators comprehensively exceed expectations.

Production effect:

1. High efficiency and energy saving

- production capacity increased to 920t/d, exceeding the design capacity of 15%;

- Coal consumption as low as 186kg per ton of lime, leading the industry in fuel efficiency;

- Full combustion without high temperature peak, kiln body temperature stable at 330-340℃, reduce heat loss.

2. Environmental protection emission reduction

- NOx emission value is stable at 30mg/m³, in line with national standards.

3. Excellent finished product

- lime activity of 380, CaO content stable at 92% (according to customer demand).

Technical highlights:

- Precise control: the multi-channel burner is equipped with regulating valve, compensation valve and intelligent control system to accurately control the air volume and flame form, and the energy saving effect is remarkable;

- Fast production: 7 days to complete the kiln to reach production, demonstrating the reliability and process maturity of the neutralizing mechanical and electrical burner equipment;

- Long-term stability: small fluctuations in operating parameters, stable thermal system, low maintenance costs, continue to create value for customers.
