Project Overview

Client Industry: Waste-to-Energy
Project Type: SCR upgrade
Location: Anji, China
Supplier: SIMO BLOWER

Project Challenges

In waste-to-energy plants, SCR systems require stable airflow conditions to ensure effective flue gas treatment.

The fan system needs to provide:

● Stable airflow for SCR system

● Different process points require different fans

● Continuous operation requirements

● Adaptability to high-temperature environments

Selecting the appropriate fan is crucial for maintaining the efficiency and reliability of the entire environmental protection system.

Why does one SCR system require different fans?

Although all three units are centrifugal fans, they serve different functions in the SCR process. The fan design, airflow capacity and pressure requirements vary according to each application point.

1. Induced Draft Fan for Flue Gas System（1set）

The induced draft fan is one of the key pieces of equipment in the flue gas treatment process.

Its main functions include:

• Maintaining system negative pressure
• Supporting smooth flue gas flow
• Ensuring stable operation of downstream treatment equipment

Main Parameters:

• Model: 1900SWB51F
• Airflow: 204,500 m³/h
• Pressure: 8,820 Pa
• Temperature: 130℃

2. Dilution Air Fan（2set）

The dilution air fan provides controlled airflow for the SCR system according to process requirements.

It helps maintain proper gas conditions and supports stable operation of the treatment process.

Main Parameters:

• Model: 400SWF26A
• Airflow: 1,500 m³/h
• Pressure: 2,200 Pa
• Temperature: 30℃

3. Sealing Air Fan（2set）

The sealing air fan provides reliable sealing airflow to prevent unwanted gas leakage and maintain equipment protection.

Main Parameters:

• Model: 500SWF19A
• Airflow: 2,000 m³/h
• Pressure: 5,200 Pa
• Temperature: 30℃
