Steam Generators & Boilers

• The most important division to define is that of Steam Generators &Boilers VS Heaters. Steam Generators and Boilers both produce watervapor, whilst Heaters increase the temperature of a thermal fluid (orsuper-heated water, which due to the high pressure does notvaporize) without actually creating any vapor.

• Fire Tube Boilers: have hot gases inside the tubes and water outsidethe tubes. It is usually internally fired, and operates under lowerpressure. It is not suitable for large power plants.

• Water Tube Boilers: have water inside the tube and hot gases outsidethe tubes. It is externally fired, and operates under high pressure. It issuitable for large power plants.

Notes:

• While Boilers can be seen as operating at sub-critical pressures, aswater actually does reach boiling point, Steam Generators more oftenoperate at super-critical pressures, thus vaporizing water instantly(water changes state without boiling). This will be the distinctionfollowed to differentiate the two systems from each other.

a.Steam generators = no boiling, water changes straight to vapor

b.Boilers = boiling is allowed to occur due to sub-critical pressures

• Fire and water tube boilers include all kinds of fuels, whether they aregaseous, liquid or solid. The only separate fuel is biomass as it isquite different from the usual coal, oil or gas fueled types.

• The division among heaters and boilers is based on what has beenheated (a direct fired heater will heat either water, thermal fluid orair). In the case of WHBs, HRSGs and WHRUs categorization is basedon the source from which we are recovering heat (a WHRU might berecovering heat from super-heated water coming from a turbineprocess).

Organic Rankine Cycle Plants Incinerators

Heaters

• The two layer division of direct and indirect fired and then by mediumheated is made to give more depth to the categorization.

• The division by fluid or gas heated is based on the fact that theyrequire very different temperatures and pressures and thus differentconstruction competences.

Notes:

• Direct fired heaters include a various range of products used fordifferent processes including: Hydrotreating, Thermal Cracking,Naphtha Reforming, Dehydrogenation, etc.)

• WHR Heaters are considered as a subset of WHR Units.

• The Organic Rankine Cycle is a thermodynamic process where heat istransferred to a fluid at a constant pressure. The fluid allows Rankinecycle heat recovery from lower temperature sources such as biomasscombustion, industrial waste heat, geothermal heat, solar ponds etc.It is in it’s own separate category as it is a specific technology.

Furnaces

• An industrial furnace is a piece of equipment used either to provideheat for a process or to serve a reactor by providing heats of reaction.Design varies as to its function, heating duty, type of fuel and methodof introducing combustion air.

• Separating by application of the furnace, is more effective thanseparating by fuel type. This is because there are larger differences tobe noted between furnaces in this categorization.

Notes:

• Furnaces are not to be confused with fired heaters. Since both have adirect flame they can be confused. However, furnaces includeapparatuses such as Electric arc furnaces, which are used to meltsteel. Direct fired heaters are not made to reach the heats furnacescan reach.

• The division by type of waste is based on the fact that thecategorization aims to be both vendor and buyer friendly. In this casethe choice of categories is buyer oriented. Knowing what kind of wastethey need to incinerate, they can find the right incinerators directly.

Notes:

• The difference between regenerative and recuperative in this caserefers to the presence of a catalyst. In brief, Regenerative incinerators(02.05.08G) refer to what is commonly known as RTOs andRecuperative thermal oxidizers (02.05.10G) refer to RCOs (catalyticoxidizers).

• This categorization was chosen also because regardless of the type ofclassification of incinerators the vendor has chosen, it can always betranslated to the proposed one. For instance, organic and animalwaste (carcasses) would most likely fall under the solid waste.

Flares

• Since Flares (02.06) are mainly used in the Oil&Gas industry, thecategorization chosen is directed towards listing the most commontypes of flares found in such plants.

Notes:

• 02.06.06G Ground flares includes all types of such flares (open,enclosed, smokeless, steam assisted, controlled combustion,invisible flaring system, etc.)

• 02.06.04G Flare tips and accessories includes, but is not limited to:Sonic tips, Pilots, Seals, Ignition control systems, Knock-out drums.

Combustion Chambers

• These were included due to their use in gas turbines, a major piece ofequipment in the Oil&Gas and power generation industries. It iscommon for them to need replacement, but they are more complexthan a simple spare part, therefore they have their own category.

• The division is based on the three most common types of chamber.

Components for Heating Systems

• This category lists the most used and demanded components for allthe previously listed heating systems.

Notes:

• The main add-ons for boilers and steam generators are listed underthe ‘accessories’ family.

• Burners play a major role in furnaces, heaters, boilers andincinerators, which is why they have their own column in thecategorization. The use-based distinction was once again chosen tobe buyer friendly.

• The ‘other components’ listed are some of the common forgedreplacement parts used for heaters, furnaces, incinerators and flares

• 02.08.11G is not limited to the parts listed in brackets; it includes allcast parts that are not mentioned in the neighbouring categories.

• 02.08.16G Special Gaskets and 02.08.17G Expansion Joints refermainly (but not exclusively) to Desox and Denox plants.

• Spare parts include anything from a replacement part (flange, gasket,door seal, controller, gauge etc.) to insulation coatings.

On a family level the priority has been given to the different type of equipment, whilst on a category level to the

characteristics of the single systems (use, heating/recovery medium and type).

Heating Equipment and Systems

This category focuses on equipment used for industrial heating purposes. The main industries served by thisequipment are the Oil&Gas and Power Generation ones.

The most widespread heating systems are boilers, steam generators (the market is expected to reach an estimated$36.8 B by 2018) and heaters. Their respective heat recovery units (WHB, HRSG and WHRU) are becoming morecommon too due to the increased efficiency they provide.

Whilst Flares and Incinerators are more for treatment (of flue gas or VOCs) the other categories are all focused onproviding heat to (Boilers, Heaters, Furnaces) or recovering heat from (ORC plants) a process.
