18-11-2015 · Inside the boiler, there will be water-wall tubes in which the water is passing and we heat the water present inside the water-tubes by burning the coal at an elevated temperature. After absorbing that heat, that water is partially converted into steam in the water-wall tubes.

BASIC STEAM CYCLE/BOILERS | Marine Notes

The condensate system is that part of the steam cycle in which the steam condenses to water and is pumped from the main condenser toward the boiler. Before it can be used in the boiler, it must be converted to feedwater which occurs in the feed phase.

Water-tube boilers differ from shell type boilers in that the water is circulated inside the tubes, with the heat source surrounding them. Referring back to the equation for hoop stress (Equation 3.2.1), it is easy to see that because the tube diameter is significantly smaller, much higher pressures can be tolerated for the same stress.

10-06-2017 · Due to continuous heat supply, some of the water gets vaporized into steam inside the tubes and a mixture of water and steam enters the boiler drum through the uptake header. The cold water from the boiler drum comes down through the uptake header and enters the lower end of the water tubes for getting heated further.

A water tube boiler is a boiler in which hot gases flows outside and surrounds the tube and water is heated inside the tube. A fire tube boiler on the other hand, basically is the opposite of the water tube boiler, where hot gases flows inside the tube and is surrounded by water on the outside.

Feedwater heater - Wikipedia

A Rankine cycle with two steam turbines and a single open feedwater heater. A feedwater heater is a power plant component used to pre-heat water delivered to a steam generating boiler. Preheating the feedwater reduces the irreversibilities involved in steam generation and therefore improves the thermodynamic efficiency of the system.

Economizer - Wikipedia

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. This is the reverse arrangement …
