Corner Tube Boiler

Corner Tube Boiler is a type of water tube boiler that uses four large corner tubes as its main supporting structure and water circulation system. This unique design makes the boiler strong, compact, and highly efficient.

Corner Tube Boiler Features

1. High thermal efficiency and lower fuel consumption

2. Suitable for coal, biomass, wood chips, rice husk, bagasse, and other solid fuels

3. Stable steam output for continuous industrial production

4. Fast installation with lower construction costs

5. Easy maintenance and long service life

6. Widely used in food processing, textile, paper, palm oil, chemical, wood processing, and biomass energy plants.

Boiler Design & Advantages

1. Self-Supporting Corner Tube Structure

The boiler uses four large-diameter corner tubes as its main supporting structure and water circulation system. It consists of a boiler drum, water-cooled walls, headers, flag-type heating surfaces, and reinforcing beams, eliminating the need for a heavy steel frame.

2. Optimized Furnace Design

The boiler drum is arranged horizontally or longitudinally outside the furnace. The high-position furnace outlet and spacious combustion chamber provide more complete fuel combustion and stable operation.

3. Full Membrane Water Wall

The furnace and convection heating area are fully enclosed by membrane water-cooled walls, offering excellent sealing performance, a larger furnace volume, and higher thermal efficiency.

4. Flag-Type Heating Surface

A unique flag-type heating surface design increases the heat transfer area by extending convection tubes from the membrane water walls, improving heat absorption and overall boiler efficiency.

5. Advanced Grate System

The boiler can be equipped with a scale-type or beam-type grate. The large isobaric air chamber ensures uniform air distribution, resulting in more efficient combustion and stable fuel burning.

6. Flexible Secondary Air Supply

Secondary air can be installed on the front and rear walls of the furnace according to different fuel types, helping improve combustion efficiency and reduce emissions.

7. Energy-Saving Heat Recovery

An economizer or air preheater is installed at the rear of the boiler to recover heat from flue gas, lower exhaust temperatures, reduce fuel consumption, and improve overall efficiency.
