Waste Heat Recovery Project at a Chemical Plant
Waste heat recovery · Qingdao, Shandong Province
Project Background
The chemical plant generates large volumes of high-temperature exhaust gas during production, reaching temperatures above 200°C. The company aims to recover waste heat for preheating raw materials to reduce energy consumption.
Facing challenges
The exhaust gas contains corrosive components, requiring corrosion-resistant materials. Heat exchange efficiency must exceed 75%. The equipment must withstand high-temperature and high-pressure conditions.
Solutions
Targeted technical solutions and product configurations
Technical Solution
Equipped with the YDG series high-temperature brazed plate heat exchanger, featuring a specialized solder alloy capable of withstanding temperatures up to 225°C. Optimized flow channels enhance heat transfer efficiency for effective waste heat recovery.
Product Configuration
- YDG10 × 6 units
- YDG08 × 4 units
Project Outcomes
Prove value with data
Waste heat recovery rate reaches 75%, saving 1200 tons of standard coal annually; equipment operates stably with no leaks or failures; payback period is just 1.5 years.
The waste heat recovery system delivers significant results and makes a vital contribution to corporate energy conservation and emission reduction.
