What is the purpose of a steam trap?
The purpose of a steam trap is discharging noncondensable and condensable gases. They are essentially automatic valves that discharge using a small amount of live steam.
What is Swelling and shrinking effect in boiler drum?
The swelling and shrinking effect in a boiler drum refers to the physical changes in the drum's volume due to temperature variations and pressure changes during operation. When the boiler is heated, the water inside converts to steam, causing the drum to swell as the pressure increases and the water expands. Conversely, when the boiler cools down or experiences a drop in pressure, the drum may shrink as the steam condenses back into water. This phenomenon is important to consider for the structural integrity and safety of the boiler system.
What is mean by Blowing factor in steam blowing?
Disturbance Or Correction or K Factor in steam blowing in Power Plants is the ratio of Drag created during steam blowing to the drag occurring during Maximum Continuous Rating. Equation of disturbance factor K is shown as below: K=ΔP1/ΔP2 ΔP1=PD1－PS1；ΔP2=PD2－PS2 ΔP1:Difference pressure of steam drum and corresponding super heater during steam blowing-out. ΔP2: Difference pressure of steam drum and corresponding super heater in normal operation of boiler
What do you understand by property of a system?
The property of steam is the precipitants ingress through the water in to the steam cycle The steam conductivity and silica contents so called property of steam. there fore the boiler drum chlorides(cause of higher conductivity in the Super heated steam) and water PH has to be controlled to get pure Super heated Steam from boiler drum risers. Silica can cause of turbine blades erosion. Higher Conductivity cause of Chlorides which can cause of Corrosion on turbine blades. PH controlled to avoid acid attack and pitting and scales deposition.
What will happen when boiler steam drum level goes down?
Overheating of water wall tubes may cause crack. Boiler will damage due to boiler drum level goes down.
What is the purpose of boiler drum?
Purpose of the boiler drum is to collect steam from all the various tubes in a boiler, and send it to the turbine to spin the generator
What is the use of steam drum in boiler?
The steam drum separated the steam from the water and stream mixture in the boiler drum.
What is function of drum in thermal power plant?
Steam drums are used on recirculating boilers that operate at subcritical pressures. The primary purpose of the steam drum is to separate the saturated steam from the steam-water mixture that leaves the heat transfer surfaces and enters the drum.
Where would a steam separator be located on a boiler?
In the steam drum, where steam exits and flows to the superheaters.
What is the area between the steam drum and the mud drum ona boiler?
Generator
What is the purpose of a drum brake?
The purpose of a drum brake is to come to a complete stop with any veichle that may have drum brakes in the rear of the car.
What is steam accumulator?
A steam accumulator on some once through boilers, with no steam/water drum, is a device similar to a steam separator, which separates the steam and water before the steam is fed to the steam header.
How do you disassemble the rear brakes on a 1993 Toyota Tercel?
pull the center cap off, pull out the cotter pin, unscrew the bolt. work the drum off ( may take some prying ) and then all the drum internals will be exposed.
What is the purpose of the kick drum resonant head and how does it affect the sound of the drum?
The purpose of the kick drum resonant head is to control the sustain and tone of the drum. It affects the sound by influencing the amount of air that can escape from the drum, which in turn impacts the depth and pitch of the sound produced.
Why boiler drum steam pressure always different from boiler main steam line pressure?
Due to pascals law
What seal pot do for steam drum?
A seal pot in a steam drum system functions to maintain a water seal, preventing steam from escaping while allowing for the proper flow of condensate and maintaining pressure. It helps manage the level of water in the drum, ensuring that the steam generation process operates efficiently and safely. Additionally, the seal pot can prevent the ingress of air and contaminants, which could impact the system's performance and integrity.
What is inclination of steam drum?
Boiler drum inclination is kept at 1:50 with the horizontal i.e. around 6 to 8 degrees.
