Chemical Treatment Requirements for Steam and Hot Water

Jun 12, 2017 · D-type boilers are flexible units with a mud drum and steam drum stacked vertically with water wall combustion chamber plus multiple convective passes. The fire is either along the drum line or at right angles to the drum. O-type boilers are also compact 2 drum design. Boiler tubes form an O-shape as they connect to the top and bottom drums.

4.5 Steam Turbines and Rankine Bottoming Cycle

The agent breaks down the NO x in the exhaust gases into water and atmospheric nitrogen (N 2 ). While NSCR can reduce boiler NO x emissions by up to 70%, it is very difficult to apply to industrial boilers that modulate or cycle frequently because to perform properly, the agent must be introduced at a specific flue gas temperature.

Steam System Balancing for Multifamily Existing Buildings

The size of the boiler outlet and the design of the near boiler piping (also known as the header piping) also have a big impact on steam quality. If the steam outlet is too small, the high exit velocity of the steam will carry water droplets along with it — hence the benefit of limiting high fire as discussed above.

Natural Gas Fired Boilers

Depending on a number of factors including coal properties, boiler efficiency typically ranges between 87% and 89% while firing coal. The boiler efficiency is usually reduced to 84-85%, when a coal fired boiler is converted to natural gas. The biggest change is due to the combustion of Hydrogen. This is normally a 4% heat loss while firing coal
