How to Calculate Boiler Steam Flows | Hunker

Use btu/hr (British thermal units/hour) heat input rate to calculate boiler steam flow. It takes 970.28 btu/hr to produce 1 pound of steam at the above conditions. If 50 million btu/hr are being applied to the boiler, divide by the 970.28-btu/lb to yield 51,531-lb/hr steam flow. This is an average industrial boiler…

Finding the Root Cause of Boiler Tube Failures

Identifying and correcting the root cause of tube failures is essential to help lessen the chance of future problems. Symptoms: Intergranular micro-cracking.Loss of ductility or embrittlement of the tube material leading to brittle catastrophic rupture. Causes: Most commonly associated with excessive deposition on ID tube surfaces, coupled with a boiler water low pH excursion.


1.Low pressure steam boilers shall only be used where steam from a central boiler plant is not available, and the steam demand is between approximately 146 kW (15 Boiler hp or 500,000 Btu/hr) and 585 kW (60 Boiler hp or 2,000,000 Btu/hr).

Boiler feedwater heaters are designed to improve boiler efficiency by extracting heat from streams such as boiler water blowdown and turbine extraction or excess exhaust steam. Feedwater heaters are generally classified as low-pressure (ahead of the deaerator), high-pressure (after the deaerator), or deaerating heaters.

Water Handbook - Boiler System Failures | SUEZ

In some steam drum designs, water level is extremely critical because the baffling may isolate a generating section of the boiler when the steam drum water level falls below a certain point. Thin-lipped bursts also occur in superheater tubes when steam flow is insufficient, when deposits restrict flow, or when tubes are blocked by water due to a rapid firing rate during boiler start-up.

Boiler explosion - Wikipedia

A boiler explosion is a catastrophic failure of a boiler.There are two types of boiler explosions. One type is a failure of the pressure parts of the steam and water sides. There can be many different causes, such as failure of the safety valve, corrosion of critical parts of the boiler, or low water level.
