Product Description

Key Highlights

Dual Blower with Automatic Changeover

Main and standby blowers operate in backup mode. When the running unit fails, the system switches automatically without manual intervention, guaranteeing uninterrupted combustion air supply for the furnace.

Customized for 400–600 TPD Glass Furnaces

Air volume and pressure parameters are matched to satisfy the steady combustion demand of container glass and float glass furnaces.

Intelligent Control & Real-Time Monitoring

The PLC control system tracks vibration, temperature, current and air pressure of the blowers, and sends alarm signals for abnormal conditions.

Compact Integrated Skid Design

Blowers, motor, inlet filter, silencer, valve assembly and control cabinet are pre-assembled, simplifying on-site installation and commissioning.

Company Advantages

We supply complete blower skid packages together with glass furnace EPC services. Our team has rich experience in glass furnace auxiliary system matching. We can adjust air flow, pressure and control logic according to your furnace layout and fuel type. Long-term after-sales support includes spare parts supply, on-site commissioning and regular maintenance guidance.

Product Overview

This duplex combustion air blower unit is a critical auxiliary equipment for glass melting furnaces. It consists of two sets of centrifugal blowers, an automatic switchover valve group, silencing and filtering components, and an electrical control cabinet. It provides stable and clean combustion air for furnace burners.

The auto-changeover function avoids sudden air supply interruption, protecting the furnace refractory structure and stabilizing glass melting quality. It is widely used for end-fired and cross-fired container glass furnaces with daily capacities from 400 to 600 tons.

Reference Case

Project: 520 TPD End-Fired Container Glass Furnace, North Africa

The customer originally adopted a single blower for combustion air supply. Unplanned blower faults had caused several furnace heat fluctuations and production losses. They selected our duplex combustion air blower unit with automatic changeover as the upgrade solution.

Scope of supply: Skid-mounted duplex blower set, inlet filter, silencer, switching valve group, PLC control cabinet and field installation guidance.
Customization: Air volume and pressure tuned for natural gas end-fired burners; auto-switch logic triggered by low air pressure, motor over-temperature and overload.
Outcome: After commissioning, the unit runs continuously. Automatic switchover has been successfully triggered during one blower motor fault, with zero interruption of combustion air. The furnace keeps stable melting conditions, glass defect rate dropped, and unplanned downtime of the furnace eliminated. The unit has maintained stable operation for over 18 months.

FAQ

Q1: What is the trigger condition for automatic changeover?

The system triggers switchover upon preset faults such as blower overload, abnormal vibration, low air pressure or motor over-temperature.

Q2: Can you adjust blower parameters for our existing furnace?

Yes. We customize air volume, pressure and rotation speed based on your furnace capacity and your oxy-fuel or air-fuel combustion scheme.

Q3: Does this unit include a silencer and air filter?

The standard scope includes an inlet air filter and silencer to reduce noise and prevent dust from entering the blower.

Q4: What is your delivery and commissioning service?

We provide skid-mounted pre-assembly, factory testing, and support on-site guidance for installation, wiring and commissioning.
