Functions Of Boiler Mounting: These are the fittings that are mounted on the boiler for its proper functioning. They include water level indicator, pressure, gauge, safety valve, etc. It may be noted a boiler cannot function safely without the mounting. According to IBR the following are the list of mountings should be fitted to the boilers. 1.

Kefid 16:21:02. Each set of tubes that hot combustion flue gas travels through before making a turn within the boiler, is considered a "pass." A 3-pass fire tube boiler design consists of three sets of horizontal tubes, with the stack outlet located on the rear of the boiler. A downdraft design keeps the cooler water from having an effect on the hot surfaces within the boiler.

configurations for each type are shown in Figs. 2.1Œ2.3, respectively. Most modern firetube boilers have cylindrical outer shells with a small round combustion chamber located inside the bottom of the shell. Depending on construction details, these boilers have tubes configured in either one, two, three, or four pass arrangements.

FEEDWATER SYSTEM TRAINING SYSTEM DESCRIPTION (IRI …

A boiler or steam generator is a device used to create steam by applying heat energy to water.Although the definitions are somewhat flexible, it can be said that older steam generators were commonly termed boilers and worked at low to medium pressure (7–2,000 kPa or 1–290 psi) but, at pressures above this, it is more usual to speak of a steam generator.

Boilers : Types and Classification

the flue gases, these boilers are also called three-pass shell boilers. Industrial boiler systems can cope with much higher pressures than pressure cookers. These boilers are welded from thick steel plates that are up to 35 mm thick, making pressures of 30 bar and more possible.

Sep 18, 2020 · The gases again turn 180 degrees; typically, the third pass has smaller bore tubes but more tubes than the second pass. Three or four pass boilers are the most common. A horizontal boiler with an even number of passes will have the flue connection near the front of the boiler and an odd number of passes has the flue at the back end.

2. BOILERS - Bureau of Energy Efficiency

The boilers can be classified according to the following criteria. According to flow of water and hot gases: 1. Water tube. 2. Fire tube. In water tube boilers, water circulates through the tubes and hot products of combustion flow over these tubes. In fire tube boiler the hot products of combustion pass through the tubes, which are surrounded
