Boiler feed water - Lenntech

The boiler receives the feed water, which consists of varying proportion of recovered condensed water (return water) and fresh water, which has been purified in varying degrees (make up water).The make-up water is usually natural water either in its raw state, or treated by some process before use.

ProLine® 50-Gallon Gas Water Heater

Gas water heaters heat water by burning either natural gas or LP (propane). Gas water heaters need a source of air and also need to be vented properly. Cold water enters the water heater through an internal dip tube which forces the cold water to the bottom of the tank and pushes hot water out through the outlet connection.

Gas detector - Wikipedia

A gas detector is a device that detects the presence of gases in an area, often as part of a safety system. A gas detector can sound an alarm to operators in the area where the leak is occurring, giving them the opportunity to leave. This type of device is important because there are many gases that can be harmful to organic life, such as humans or animals.

The Production of Hydrogen Gas: Steam Methane Reforming

1. Water enters the furnace, producing steam at a very high temperature. 2. Steam reacts with natural gas, producing hydrogen and carbon monoxide. 3. In the water shift reactor, carbon monoxide and steam react to form carbon dioxide and more hydrogen gas. 4. The hydrogen gas is purified to the customers specifications, removing contaminants. 5.

Combined cycle power plant - Wikipedia

The thermodynamic cycle of the basic combined cycle consists of two power plant cycles. One is the Joule or Brayton cycle which is a gas turbine cycle and the other is Rankine cycle which is a steam turbine cycle. The cycle KefidKefid which is the gas turbine power plant cycle is the topping cycle. It depicts the heat and work transfer process taking place in high temperature region.

An Overview of Combined Cycle Power Plant

Jun 26, 2020 · The gas turbine and steam turbine are coupled to a single generator. For startup, or open cycle operation of the gas turbine alone, the steam turbine can be disconnected using a hydraulic clutch.In terms of overall investment a single-shaft system is typically about 5 per cent lower in cost, with its operating simplicity typically leading to higher reliability.
