Boiler feed pump KSB

Boiler feed pumps are also referred to as feed pumps (see Reactor pump) and designed as multistage radial flow pumps. (Also see Multistage pump.) They serve to feed a steam generator such as a boiler or a nuclear reactor with a quantity of feed water corresponding to the quantity of steam emitted. Today, all boiler feed pumps are centrifugal pumps.

Finding the Root Cause of Boiler Tube FailuresFailures result when the tube metal temperature is extremely elevated from a lack of cooling steam or water flow. A typical example is when superheater tubes have not cleared of condensation during boiler start-up, obstructing steam flow. Tube metal temperatures reach combustion gas temperatures of 1600F (870C) or greater which lead to tube

Principals of Condensing Boiler System Design

ANSI Standard Z21.13 tests and rates condensing boiler performance with an 80F (27C) boiler entering water temperature (EWT) and a 100F (55C) temperature rise (delta-T) to produce a boiler leaving water temperature (LWT) of 180F (82C). Condensing boiler performance is dominated by the boiler EWT.

Steel Standards - ASTM International

ASTM's steel standards are instrumental in classifying, evaluating, and specifying the material, chemical, mechanical, and metallurgical properties of the different types of steels, which are primarily used in the production of mechanical components, industrial parts, and construction elements, as well as other accessories related to them. Steel properties at low and high temperatures ::Total Figure 2. Effect of low temperatures on the mechanical properties of steel in plain and notched conditions. Surface grinding with grit coarser than 180 and shot-blasting causes embrittlement at -100°C due to surface work-hardening, which, however, is corrected by annealing at 650-700°C for 1 h.

The Metallurgy of Power BoilersAs an aside, all hot forming and shaping employed to make boiler tubes and piping is done in the austenite temperature range of 1650 o F to 2000 o F. With the continued cooling, the face-cantered-cubic austenite begins to transform to body-centered-cubic ferrite at a temperature of around 1600 o F, and again, the exact temperature depends on
