Miscellaneous Boiler Types Economisers and Superheaters

In water-tube boilers, the superheater may be an additional pendant suspended in the furnace area where the hot gases will provide the degree of superheat required (see Figure 3.4.4). In other cases, for example in CHP schemes where the gas turbine exhaust gases are relatively cool, a separately fired superheater may be needed to provide the

Economizer - an overview | ScienceDirect Topics

In shell boilers with a working pressure of between 7 and 17 bar the temperature of the mass of water in the boiler is typically in the range of 170–210°C. Allowing for, say a temperature difference of 30–50°C between the exhaust gases and the water temperature, the boiler exit gas temperature cannot be economically reduced beneath about

I Learned from That: Hot Well Overflow causes Boiler Tubes

Have you ever seen the pictures of boiler (Exhaust gas Economizer) tubes melted completely? Read here to know about the sequence of events, to which all the engineers on board ship failed to understand and react. This caused the exhaust gas boiler tubes to melt down completely which caused a loss of over a few million dollars. Check out here to see the pictures of internal structure of a boiler.

Boiler Economizers | CBW Industrial Boiler Waste Heat

The installation of a boiler economizer helps to solve this problem. An economizer is a unit that captures heat from the stack, and then returns it to a water system. To determine if a boiler economizer is right for your facility, look at your annual boiler fuel bill and subtract 5 to 10% of the cost.

3 Use of Economizer with Waste-heat Boiler. Where the exit gas temperature is above ca.225°C and the ratio of flue gases to weight of water evaporated is low (e.g. < 3:1), the use of an economizer may be justified economically. Under these circumstances the exit gas temperature may fall to < 140°C.
