1.4 Considered Concept of triple pressure HRSG boiler

The triple pressure HRSG of this model has following pressure levels at their respective exit points :

1. High Pressure level : 123 bar(a) at 568°C 2. Intermediate Pressure level : 31,41 bar(a) at 567°C 3. Low Pressure level : 5 bar(a) at 320°C

Based on previous HRSG designs, following arrangement of the different heating modules in flue gas direction was selected:

• HP - Superheater 1( outlet) • IP - Reheater 1 (outlet) • IP - Reheater 2 • Duct Burner • HP - Superheater 2 • HP - Superheater 3 • IP - Reheater 3 • HP – Superheater 4 • HP – Evaporator • HP – Economiser 1 • IP – Superheater • LP – Superheater • HP – Economiser 2 • IP – Evaporator • IP – Economiser • HP – Economiser 3 • HP – Economiser 4 • LP – Evaporator • Condensate Heater

In this model, with horizontal gas flow, all modules consist of multiple rows with vertical serrated fin tube, all of the same height. Following action has to be repeated for each module:

(10) Drag and drop from the ” HHeeaattiinngg SSuurrffaaccee” menu the “HHSSffiinnnneeddTTuubbeess” – icon and drag and drop it into the flue gas scheme, select further image “WWTT22” (11) and click on (12) OK.

In the studied case, again 5 zones are installed and gas flow and temperature distribution at 100%, considering a uniform distribution after the first modules and the duct burner. Flue gas connection must be made the same way as between previous modules

1.6 Selection of the fuel for the duct burner

From the short-cut to schemes, select ”DDuuccttbbuurrnneerr FFuueell SScchheemmee” and select from the menu Fuel elements the appropriate fuel nature, i.e. gas.

1.7 Incorporation of the remaining modules after the duct burner As indicated under 1.4 the next 15 modules are introduced into the flue gas scheme. This can easily been achieved by placing the cursor on a previous module, with a right mouse click a menu appears and with the function “ DDuupplliiccaattee” an additional module is created which can be dragged to its correct location.

This must be repeated as needed to complete the configuration of the HRSG. The names of the copied modules must be accordingly adjusted (right mouse click on the module, select properties and change name in first window (23)). Also the necessary flue gas connections between the modules must be made (24).

REMARK:

The HP-Evaporator consist normally of a larger number of modules, and they are therefore in this scheme grouped and represented by a gas-group icon in the AAllllDDaattaa__11..FFlluueeGGaassSScchheemmee,, which can be opened by clicking with right mouse button and selecting the option: open group. A new underlying HHPP EEvvaapp..FFlluueeGGaassSScchheemmee is created where a more detailed construction of the HP-Evaporator can be specified.

The purpose of creating a separate HP-Evaporator scheme is to allow a detailed study of the heat transfer through the several screens and other specific values. To complete the flue gas circuit, we have to mix the flue gas streams, a second test point is added and also a stack. In order to calculate the thermal balance and efficiency, we have to confirm (25) the first elements or inlet of heat input (1) and the last elements (L) or outlets of heat considered as losses.

3 Integration of the several control loops 3.1 Control loop for fuel-supply to ductburner

In this model, the heat capacity of the duct burner must keep the flue gas temperature at a constant value, i.e. 600°C at the outlet of the Ductburner. The fuel supply will be controlled in function of the measured flue gas temperature at test point TP1. Form the shortcut to schemes we select the “DDuuccttbbuurrnneerr..FFuueell SScchheemmee” and from the element list we select the CCoonnttrrooll EElleemmeennttss.. The element “FFuueellCCttrrll” is dragged into the Fuel scheme and connected to the fuel supply with the connection “ccoonnnnFFuueell”. This control element is further called in the AllData_1FlueGasScheme with the meanwhile known procedure with right mouse button click on the background Properties add/delete model. The “Ductburner Ctrl” element is in this scheme connect via “ CCoonnnnGGaassTTeessttPPooiinntt” to the Test-Point “TP1” in the flue gas scheme.

3.2.2 Control of water inlet-temperature of the Condensate Heater

To avoid flue gas condensation in the condensate heater, water temperature should be above dew point, in our case ≥ 60°C. As the boiler-feedwater (condensate) is about 40°C, temperature at the heater-inlet is lifted to 60°C by recycling a fraction of the water flow from the outlet of the heater. The used control valve is a multi-purpose element that can be used to control different values as :

o Input temperature gas o Input temperature H20 o Set volume flow o Set Weight flow o Set Weight flow gas-side o Steam content o Temperature over evaporator temperature ….

In our example we select option “IInnppuutt TTeemmpp HH22OO” for this control loop, and fill in 60°C as set-value for “tt HH22OO SSVV”.

4.2 Excel Input Data

An alternative and easier way to introduce the input values into the HRSG structure is via an Excel-file. Once the boiler structure is fixed in the report file, it can be transferred to an Excel-file via the function “ TTrraannssffeerr EExxcceell”. This excel-file can then be named and stored. Changes in design during e.g. an optimisation process, can be inserted in the excel-file and again loaded in the structure the function “ IImmppoorrtt ffrroomm EExxcceell”. (typical layout see below)

The hydraulic pipe system can be further extended with all interconnecting piping when the piping lay-out is fixed and exact number of piping connections, number of bends and other restrictions are finalised. These input data are not only needed for the natural circulation calculation of the evaporator systems, but also to calculate exact pressure drop with the interconnecting piping between economisers, steam drums, evaporators superheater’s and other equipment in the total water/steam circuit. To perform the natural circulation, the module “Circulation” the calculation option “Circulation” must be ticked in the respective box.
