Drum level is frequently also measured by Eye-Hye – a device like a sight glass with relays to indicate whether each point (separated by an inch or two) has water or not.Because the temperature of the water in the Eye-Hye is colder and more dense than the water in the drum, the water in the Eye-Hye tube will be several inches lower than the level in the drum
Silica must be held below pressure-dependent limits, as silica will vaporize, carry over with steam, and precipitate in the turbine. This effect becomes dramatic as pressure increases. For example, in a 900 psi boiler the recommended maximum drum water silica concentration is 2.8 ppm. In a 2,400 psi boiler the recommended maximum is 0.21 ppm.
2019-12-3 · Boiler water treatment is the conditioning and treatment of boiler feed water with the purpose of meeting three objectives. In order for boiler water treatment to be maintained, there must be a continuous heat exchange, protection for high-quality steam, and corrosion protection. Boilers are designed to heat fluid, after which the vaporized or heated fluid will exit the boiler
2020-8-29 · GWR provides the reliable measurement that is needed for improved boiler and steam drum level control. With better level control, an operation can reduce heat rate, environmental impact, fuel and water consumption, water treatment and maintenance costs in commercial and heavy industries where steam generation is essential to the production
2019-5-10 · A flow meter (or flow sensor) is an instrument used to measure linear, nonlinear, mass or volumetric flow rate of a liquid or a gas. When choosing flowmeters, one should consider such intangible factors as familiarity of plant personnel, their experience with calibration and maintenance, spare parts availability, and mean time between failure history, etc., at the
Technologies historically used for boiler and steam drum level control rely on inference or buoyancy to determine the level. This in itself leaves them vulnerable to process dynamics (specific gravity, pressure, temperature, etc.) or limits their ability to precisely manage the level for improved fuel economy.
2021-2-19 · The Electric Power Research Institute (EPRI) conducts research, development, and demonstration projects for the benefit of the public in the United States and internationally. As an independent, nonprofit organization for public interest energy and environmental research, we focus on electricity generation, delivery, and use in collaboration with the electricity sector, its

Dial Dwyer offers different types of Dial Flowmeters for various applications. Flow meters measure water, oil, gas or air flow rates. Applications include calculating required fill or drain times for tanks, water towers, backflow prvention, heat exchangers, and oil & gas equipment.
The low pressure side senses the boiler drum pressure, the weight of the water above the low pressure tap and the weight of a column of saturated steam from the high pressure tap to the water level. Being a differential pressure device, the boiler drum pressure is canceled out of the measurement, leaving only the water column pressure difference.
US5148775A - Feedwater control for drum type steam
An improved feedwater control for drum type steam generators is provided in order to gain improved drum level control for drum type steam generators which are subjected to great load changes at high rates of change. The control system accounts for changes in the mass inventory within the circulation lop by monitoring and adjusting to changes in steam flow and drum

2020-12-16 · As boiler drum pressure swings with steam consumption or load swings, the drum water level swells (at reduced pressure) owing to gases in the boiler water volume. Make sure that the feedwater level control is capable of overriding these swells. 5. Safety Relief Valves Make sure that all safety valves are securely anchored for reaction jet forces.
