Boiler Safety - OSHA Safety Manuals
Mar 15, 2017 · Boiler Safety. Workers that use, maintain, and service boilers know that they can be potentially dangerous. Boilers are gas-fired or electric closed vessels that heat water or other liquid to generate steam. The steam is superheated under pressure and used for power, heating or other industrial purposes.Get Price

Water Level Gage Steam Boilers: Observe the blowdown of the water gage in its normal manner and the promptness of the return of water in the gage should be noted. During the test of the water level gage, water and steam connections should be blown separately to ensure both are clear. Safety and Safety Relief ValvesGet Price
Steam Generator Management (QA) - EPRI
Alkaline water flushes are usually performed with potable-quality tempered water. Flush velocity should be greater than system design velocity. After the flush, the condenser hot well, deaerator, and deaerator storage tank are usually cleaned by hand, because these units do not drain completely. Steam blowing normally follows the last boiler and economizer chemical cleaning …Get Price
Steam Calculators: Boiler Calculator - Energy
Mar 17, 2015 · 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.Get Price
What is Steam Turbine - Description and Characteristics
What is Steam Turbine – Description and Characteristics. In general, a steam turbine is a rotary heat engine that converts thermal energy contained in the steam to mechanical energy or electrical energy. A steam turbine consists of a boiler ( steam generator ), turbine, condenser, feed pump, and various auxiliary devices in its simplest form.Get Price
Anatomy of a Catastrophic Boiler Accident
When the second turbine generator was started, this valve was opened to allow for steam at 600 psi and 850 degrees to pass. As this valve got hot, the nuts were expanding at a much greater rate than the bolts, and they lost the strength to contain the steam's force under the bonnet. This tragic accident should not have happened.Get Price
Controlling TDS in the Boiler Water - Spirax Sarco
The steam, being a gas, can travel much faster than the water (liquid). However, the steam and water do not have the opportunity to separate properly, which results in water droplets travelling at a very high velocity with the steam into the pipework. This leads to further erosion and possibly waterhammer in the pipework and downstream equipment.Get Price
