Horizontal corner tube gas boiler

Price: $3,500.00 - $48,000.00

A corner tube boiler is a natural circulation water tube boiler. It differs from other water tube boilers in that it has the characteristics of a water-steam cycle. The pre-separation of heating steam and steam-water mixture occurs outside the drum in an unheated downcomer. This type of boiler is called a corner tube boiler.

Rated thermal power: 25 - 50t/h
Rated thermal efficiency: ≥99%
Operating pressure: ≤3.82MPa
Available fuel: Natural gas, city gas, gas, coke oven gas, light diesel, etc.

Low Nitrogen Environmental Protection, High
Efficiency & Energy Saving

Strong stability

The main body adopts an integral corner tube self-supporting structure, which has high strength, strong stability, safety and reliability, and will not cause jitter or surge.
Large drum space

The drum has a large space and a unique drum internal design with good steam-water separation effect, ensuring steam quality and superheater safety.
Ultra-low nitrogen combustion

The super-large furnace design not only has greater furnace heat storage, faster boiler startup and shutdown, and wider load adjustment range, but is also more conducive to ultra-low nitrogen combustion.
safer

The hot water boiler adopts forced circulation + natural circulation (auxiliary), and the steam boiler adopts natural circulation + forced circulation (auxiliary). The larger the density difference between steam and water is, the safer the water circulati
