The first successful economizer design was used to increase the steam-raising efficiency of the boilers of stationary steam engines.It was patented by Edward Green in 1845, and since then has been known as Green's economizer.It consisted of an array of vertical cast iron tubes connected to a tank of water above and below, between which the boiler's exhaust gases passed.
22 BOILERS SIMPLE BOILER Principle-A boiler is a closed vessel in which steam is generated from water by the application of heat. The simple boiler is like a barrel, consisting of a cylindrical steel shell, with the ends closed by flat steel heads. It is partly filled with water and then sealed, after which a fire is started beneath it.
> How do gas-fired power stations work? The reason that gas fired power stations are currently so popular is that they are very much more efficient than traditional thermal power plants. The reason for this efficiency is that they operate in a di
Drum boiler or HRSG (drum-type) Boiler in which steam (generated in heated evaporator tubes) is separated from water in an unheated horizontal pressure vessel (drum). The liquid phase is recirculated to the evaporator. Feedwater Water that is pumped into a boiler or HRSG to balance the steam production
A HRSG generates steam by capturing heat from the turbine exhaust. These boilers are also known as heat recovery steam generators. High-pressure steam from these boilers can be used to generate additional electric power with steam turbines, a configuration called a combined cycle.
To get the best efficiency for a combined cycle plant the Heat Recovery Steam Generators (HRSG) operates on with three different pressure circuits. This article explains why this is required.In an HRSG, as in any boiler, water converts to superheated steam in three different sections. The economizer , the evaporator and the Superheater. Heat transfer is dependent on the mass flow of the hot
Cover photo: Example of an 18 MW biomass power plant in Aberdeen, Washington State, USA. PNG Biomass grows up to 10 million seedlings a year in nurseries in the Markham Valley in Papua New Guinea. They will generate 30 MW of electrical power by growing the seedlings into trees, processing the timber logs into woodchips, 
A heat recovery steam generator (HRSG) is a solution, when you need to recover heat from a hot gas stream. With our solution, you can produce steam that can be used in a process (cogeneration) or used to drive a steam turbine (combined cycle). Our boilers are manufactured either in horizontal or vertical types.
Learn the basics of HRSG inspection. The global economic downturn will impose new challenges on plant operations.It's difficult to believe that you will be asked to do more with a smaller budget, but you will. However, approaching these new challenges with a positive mindset can yield significant benefits.

The boilers are fitted with different safeties as the steam pressure is up to 8 bars in most cases. There are normally two kinds of boilers on ships, Auxiliary and Exhaust, some ships have composite boilers. Boiler are of two type. STB (Smoke tube Boiler) or donkey boiler; WTB (Water tube Boiler) or High pressure boiler
Working Principle of a Boiler. The boiler works on the same principle as the water is heated in a closed vessel and due to heating, the water changes into steam. This steam possesses high-pressure kinetic energy. The boiler contains water. The water is heated to its boiling temperature by the use of heat from the furnace.
The stop or crown Valve isolates the boiler and its steam pressure from the process or plant. If steam is pressurised, it will occupy less space. Steam boilers are usually operated under pressure, so that more steam can be produced by a smaller boiler and transferred to the point of use using small bore pipework.

Working Principle of Economizer As shown in the figure above, the flue gases coming out of the steam boiler furnace carry a lot of heat. Function of economiser in thermal power plant is to recover some of the heat from the heat carried away in the flue gases up the chimney and utilize for heating the feed water to the boiler.
Generally, a steam boiler is a type of closed container, designed with steel for heating the water to generate steam by some energy source like burning of fuel with eventually. The vapor generated may be delivered at low-pressure for the industrial progression work in sugar industries, cotton mills, and for generating steaming water that can be utilized for heat up fixing at much low-force.
