What is Otsg boiler?
The OTSG has a vertical-shell counterflow straight-tube heat exchanger design, which directly generates superheated steam as the feedwater flows through the steam generator in a single pass.
What is steam generation theory?
Steam Generation Theory Within the boiler, fuel and air are force into the furnace by the burner. There, it burns to produce heat. From there, the heat (flue gases) travel throughout the boiler. The water absorbs the heat, and eventually absorb enough to change into a gaseous state – steam.
What are the stages of steam generation?
In a steam-driven turbine system, water is heated in the steam generator to produce high-temperature, high-pressure steam. Steam is then expanded in a turbine to produce electricity from a generator. Turbine steam is condensed back into water in the condenser. A pump then returns the water to the steam generator.
How steam is generated in boiler?
A boiler incorporates a firebox or furnace in order to burn the fuel and generate heat. The generated heat is transferred to water to make steam, the process of boiling. This produces saturated steam at a rate which can vary according to the pressure above the boiling water.
What does Otsg stand for?
OTSG
| Acronym | Definition |
|---|---|
| OTSG | Office of the Surgeon General |
| OTSG | Once-Through Steam Generator |
| OTSG | Office of Tribal Self-Governance (Rockville, MD) |
| OTSG | Operations Technical Support Group |
What is Otsg in oil and gas?
Once Through Heat Recovery Steam Generators (OTSGs) are the most significant advancement in steam generation in over a century. Until the 1980s, conventional drum boilers were used to produce steam.
What is boiler PPT?
TYPES OF BOILERS Horizontal, vertical or inclined Fire tube and Water tube Externally fired and internally fired Forced circulation and natural circulation High pressure and low pressure boilers Stationary and portable Single tube and multi-tube boilers Fluidized bed boiler Pulverized fuel boiler.
What is the difference between boiler and steam generator?
For example, look at the difference between “steam generators” and ”steam boilers.” A steam boiler generates energy by generating steam, and a steam generator generates energy by generating steam, so . . .
What is steam chemical formula?
Answer. Steam is basically water in its gaseous form so it can be chemical components is H2O.
How is steam generation calculated?
Calculation Details
- Blowdown Mass Flow = Feedwater Mass Flow * Blowdown Rate.
- Steam Mass Flow = Feedwater Mass Flow – Blowdown Mass Flow.
- Steam Mass Flow = Feedwater Mass Flow – Feedwater Mass Flow * Blowdown Rate.
- Feedwater Mass Flow = Steam Mass Flow / [ 1 – Blowdown Rate ]
What are the 3 types of boilers?
There are three main types of boilers you can install into your home: combi boilers, heat only (regular boilers) and system boilers.
What is boiler principle?
Working Principle of Boiler Hot gases are produced by burning fuel in the furnace. These hot gases are made to come in contact with the water vessel where the heat transfer takes place between the water and the steam. Therefore, the basic principle of the boiler is to convert water into steam by using heat energy.
What is the risk of silica salt deposition in OTSG boiler tubes?
The risk of silica salt deposition in the boiler tubes becomes significant when the silica content in the feed water exceeds 100 mg/l (OTSG boiler supplier specifications). Deposition of silica increases local thermal resistance and can lead to tube failure.
What is an OTSG system?
OTSG systems employ alloy 825 and stainless steel fins in the inlet rows (economizer) of all the pressure levels and a preheater is not required. These materials minimize the effects of corrosion; therefore the OTSG systems accommodate lower feedwater (as low as 60°F) and therefore lower stack temperatures. HP Jumper Tube
Can Silica scale inhibitors be used in steam generation in OTSG boilers?
Deposition of silica increases local thermal resistance and can lead to tube failure. The silica removal process is also an environmental issue owing to the production of sludge. This paper demonstrates that silica scale inhibitors can be used in steam generation in an OTSG boiler.
How to boil water in an OTSG?
This is a schematic for an OTSG. One valve to control the total flow of water. Then pass balancing valves. Wind down through the convection section, and get warmer. Boiling starts at the exit of the convection section. Then a few laps back and forth across the radiant section.
