Steam Calculators: Boiler Calculator

Steam, Boiler, and Blowdown Pressure are the same. Combustion Efficiency is the % of fuel energy that is directly added to the feedwater and not otherwise lost or used. Blowdown Rate is the % of incoming feedwater mass flow rate that leaves the boiler as a saturated liquid at boiler pressure.

US6655322B1 - Boiler water blowdown control system

The present invention relates to a method for automatically maintaining the concentration of scale forming minerals in boiler water for boiler systems utilizing bimodal feedwater pumps that deliver a substantially constant feedwater flow to the boiler drum when activated. According to the present invention, the feedwater supply pump and blowdown rate control valve are synchronized to remove

Bottom Blowdown | GESTRA

Intermittent blowdown is achieved by the valve cone opening very quickly. This briefly produces "vacuum" at the bottom of the boiler. The resulting suction removes settled sediment on the floor of the boiler, also known as boiler sludge, from the boiler.

Blowdown Heat Recovery | CleanBoiler.org - Boiler

Blowdown Heat Recovery Introduction. All steam boilers must blowndown to reduce the amount of TDS in the boiler water. See Blowdown However, along with the solids, boiler chemicals and thermal energy is lost; blowdown heat recovery systems cannot recover the chemicals, but they do recover up to 90% of the heat energy that would otherwise be lost down the drain.

2015-6-12 · Boiler bottom blowdown is the process used to manage suspended solids. As water is evaporated to form steam, the level of suspended solids increases. Water treatment chemicals are often added causing the particles to gather together (flocculate) and fall to the bottom of the boiler. Precipitated solids
