There are two types of boiler blowdowns -continuous and manual. A continuous blowdown utilizes a calibrated valve and a blowdown tap near the boiler water surface. As the name implies, it continuously takes water from the top of the boiler at a predetermined rate. A continuous blowdown is an optional feature and is not included on all boilers.

A steam boiler evaporates liquid water to form steam, or gaseous water, and requires frequent replenishment of boiler feedwater for the continuous production of steam required by most boiler applications. Water is a capable solvent, and will dissolve small amounts of solids from piping and containers including the boiler.
Aug 22, 2016· In every steam boiler, there is a blowdown separator. Blowdown is very important since it pulls the sludge from the bottom of the boiler reducing the possibility of build up. This tank allows for
Boiler blowdown. A steam boiler evaporates liquid water to form steam, or gaseous water, and requires frequent replenishment of boiler feedwater for the continuous production of steam required by most boiler applications. Water is a capable solvent, and will dissolve small amounts of solids from piping and containers including the boiler.
Several short blowdown events remove sludge more effectively than a single continuous blowdown. Shorter blowdown events cause less significant changes in boiler water level, and are safer during periods of high steam demand. Bottom blowdown piping drains the lowest parts of the boiler so it can be used to drain the boiler for servicing.
Many high pressure steam boilers require continuous surface blowdown to maintain acceptalbe levels of total disolved solids (TDS) in the boiler. The energy wasted through continuous surface blowdown may be a significant waste of energy, which may make it easy to …

Maximum continuous rating (MCR) is the capability of steam boiler to produce and provide the stated quantity of steam continually and easily with no all kinds of deficit or unwanted effects (for example overloading, slagging or overheating) upon the principal steam boiler and its components.
Two components separate the single boiler cleaner from the continuous fill; a pump and a reservoir. Water is filled into a non-pressurized "cap less" chamber and water is pumped into the boiler in small increments allowing "non-stop" cleaning, preventing the need to refill and reheat the boiler.
Continuous Blowdown. There is a steady and constant removal of a small stream of concentrated boiler water through continuous blowdown valve usually connected at the water level of the boiler, and replacement by the steady and constant inflow of feed water. This ensures constant TDS and steam purity at the given steam load.
Very Low to No Moisture even during start-up in the OAB or GHGA. MHI BoilerFree™ Technology allows for continuous super-heated steam generation unlike a boiler which has to fill up a steam chamber then discharge the steam in a batch mode. Energy efficient is reported socket to output. Nearly 90-99% Outlet to Output Efficiency, MHI Rating.
