What are steam systems for?

What are steam systems for?

Steam systems are commonly used in industrial, commercial, institutional, power, and process applications to supply heat or to turn turbines. The development of steam systems dates back to the eighteenth century.

What are the 2 types of steam heating system?

There are two main types of steam boilers, both of which are uniquely specific, known as fire tube and water tube boilers. The configurations of these boilers control how they operate and affect the entire steam boiler system.

What is the most efficient steam boiler?

Condensing Boiler Condensing boilers can be the most efficient type of boiler, often achieving a fuel-to-steam efficiency rate of up to 99 percent. These boilers recover part of the latent heat from unused water vapor that is wasted by other types of boilers by returning it to combine with the boiler water.

What is the difference between steam and condensate?

Condensate is the liquid formed when steam passes from the vapor to the liquid state. In a heating process, condensate is the result of steam transferring a portion of its heat energy, known as latent heat, to the product, line, or equipment being heated.

What are the main parts of a steam process system?

Every steam system consists of the following major components:

• Boiler. In the boiler, heat is added to liquid water to generate steam at a certain pressure.
• Steam Manifold. Smaller diameter piping connects the steam header to a steam manifold.
• Condensate Manifold.
• Gleason Steam Gauge.

What are different types of steam?

Types of Steam

• Pressure-Temperature Relationship of Water & Steam.
• Saturated Steam (Dry)
• Unsaturated Steam (Wet)
• Superheated Steam.
• Supercritical Water.
• Various States of Water.

What are the advantages of a steam heating system?

Benefits

• Smaller mass flow rate for same quantity of heat transferred (by factor 10 – 50)
• No circulating pumps required.
• Smaller pipe cross-sections.
• Possibility of very fast uniform heating-up at heat consumers.
• Fast and precise temperature control possible by adjusting steam pressure.

Are new steam boilers more efficient?

Many older non-condensing boilers have efficiencies ranging from 70% AFUE to 80% AFUE, and boilers older than 25 years could be at 65% or even lower. New condensing boilers have efficiencies of 90% AFUE and better. Replacing an old non-condensing boiler with a condensing boiler provides as much as 30% more efficiency.

What is the pH of condensate water?

between 2 and 4
Condensate drains The condensate expelled from a condensing water heater is acidic with a pH of between 2 and 4, so it is critical that the appropriate materials are used in all piping where this liquid is present. In high temperature areas, like the flue, stainless steel must be used to prevent corrosion.

What is the difference between high and low pressure steam?

   Typically, steam below 50-psig (3.5 barg) is termed as low pressure steam. Steam above 50-psig (3.5 barg) but below 250-psig (17.5 barg) is termed as medium pressure steam. Steam above 250-psig (17.5 barg) is termed as high pressure steam.
