Principle of Boiler | Kawasaki Thermal Engineering

Once-through boiler is composed of water tubes where water is supplied from one end of tube and steam is extracted from the other side. Small amount of boiler water can generate steam quickly. Installation space can be saved due to compact size.

Once-through boilers need advanced automation and control systems because of their relatively small water/steam volume. They do not either have a buffer for capacity changes as other water tube boiler types do. Once-through boiler types General There are three main types of once through boilers: Benson, Sulzer and Ramzin design.

Coil Type V/s Shell Type Boilers

A coil type boiler is water tube design, the water travels through the coil and is surrounded with flue gases. The steam generated is directly fed to the process. There is no scope for steam storage as these are once through type boiler. Shell and tube type boilers have adequate steam space above the normal water level of the shell.

Rifle Tubes | Canada's Oil Sands Innovation Alliance - COSIA

In 2014, Devon conducted a commercial-scale field pilot of a technology called rifle tubes, which had the potential to enable once through steam generator (OTSG) boilers to improve the quality of steam generated from 78 percent up to 90 percent steam quality, reducing water use and boiler blowdown, while increasing energy efficiency.

Steam Generator vs. Steam Boiler | Powerhouse

The water flows through the smaller diameter boiler tubes while the combustion gases travel around them to transfer heat to the water. The boiler tubes in the watertube design carry the heated water inside the tubes between the lower drum (mud drum) and upper drums (steam drum), with the generated steam accumulating in the upper drum.

Finding the Root Cause of Boiler Tube Failures

Components typically affected: This type of boiler corrosion fatigue is commonly found on furnace wall tubes of coal-fired once-through boiler designs, but has also occurred on tubes in drum-type boilers. Solutions: Reduce the ramp rates during start-up and shut-down to reduce the thermal stresses. Optimize sootblowing operations to minimize
