What is the purpose of a boiler blowdown tank? Boiler blowdown is the removal of water from a boiler. Its purpose is to control boiler water parameters within prescribed limits to minimize scale, corrosion, carryover, and other specific problems. Blowdown is also used to remove suspended solids present in the system.

Boiler blowdown is water intentionally wasted from a boiler to avoid concentration of impurities during continuing evaporation of steam. The water is blown out of the boiler with some force by steam pressure within the boiler. Bottom blowdown used with early boilers caused abrupt downward adjustment of boiler water level and was customarily expelled downward to avoid …

Jan 13, 2017 · Minimizing your blowdown rate can substantially reduce energy losses, as the temperature of the blown-down liquid is the same as that of the steam generated in the boiler. Minimizing blowdown will also reduce makeup water and chemical treatment costs. As water evaporates in the boiler steam drum, solids present in the feedwater are left behind.

Recover Heat from Boiler Blowdown Heat can be recovered from boiler blowdown by using a heat exchanger to preheat boiler makeup water. Any boiler with continuous blowdown exceeding 5% of the steam rate is a good candidate for the introduction of blowdown waste heat recovery. Larger energy savings occur with high-pressure boilers.

Heat Recovery from Boiler Blowdown (TDS control only) The previous module discussed the water to be blown down from a boiler in order to maintain an acceptable TDS level. This water has a number of characteristics: -The water is generally unsuitable for other applications. -The dirty water may present a disposal problem.

Introduction. Improvements in efficiency of boiler and steam systems can result in significant operating cost savings. Audits have indicated that 15 – 20% fuel savings can be achieved with a payback period of less than 2 years. In addition, total annual emissions of air pollutants, such as NOx and CO2 are also reduced.

Three general types of measures can reduce the amounts of water used in boiler and steam systems: 1) optimized condensate recovery; 2) improved water treatment and monitoring to minimize boiler blowdown; and 3) good operation and maintenance programs for steam lines, steam traps, feed pumps, condensers, heat exchangers, and boilers.

Manual blowdown control cannot maintain this level of control more than 20% of the time. Upgrading from manual blowdown control to automatic control can reduce a boiler's energy use by 2 – 5 percent and blowdown water losses by up to 20 percent. Feed water usually contains one limiting component such as chloride, sulfate, carbonate, or silica.

In general blowdown rate is taken as 1% of the feed water flowing into the boiler. Therefore, for a single power plant unit of 300MW capacity, the boiler blow down rate is 10.25ton/h. According to the past operating data of the power station [4] (for the month of October 2015), average blowdown flow rate is 10 ton/h (in liquid water state) and it
