Identifying Challenges and Solutions in Electric Ladle PreheatingLeonardo ENERGY
Foundries use ladles to transfer molten metal from the melt operation to cast operation. Currently, gas and oil firing are the most common method of drying and heating of refractory lined ladles, tundishes, soaking pits and various furnaces in steel mills and other small and big foundries. Convective heating for heating the refractory linings can be achieved by using dedicated burner setups for ladles and tundishes. However, this method has very low efficiency, in the order of 5-25%. Alternatively, electric ladle pre-heating offers many advantages over the current methods. In this webcast, the current practices used in foundries for pre-heating ladles, some of the disadvantages of the current practices, and few potential solutions to improve efficiency of this process will be covered.

Introduction to Floating Storage & Regasification Unit (FSRU)petroEDGE
Over the next 2 or 3 decades it is predicted that gas usage will grow at a much faster rate than oil and become the dominant energy source. Up to some 40% of gas comes from Offshore Fields. The transport of gas in the form of LNG is growing very fast – particularly for longer distance export routes. New offshore opportunities for gas production are being developed with the new technologies of Floating LNG (FLNG).
Inshore or Offshore FSRU’s provide safe, strategic and good location for the receiving terminals for LNG and provide the conversion of the methane from the liquid phase back to the gaseous phase to direct consumer usage.
This 2 day training course covers Gas and LNG activities – their Supply Chain from Onshore and Offshore Gas Fields to Market, with FSRU’s providing the last step by converting the LNG back to usable methane gas for local supply and use. Case Studies and videos will be used to illustrate lessons learned from past successful projects. A DVD of the powerpoint presentation and numerous Industry videos will be distributed with the lecture materials.

INTERNATIONAL EXPERT GAS TURBINES
The aims of the O&M of Gas Turbines Workshop is to share the experiences of our internationally renowned expert with an aim to prevent such incidents and also to examine the factors and opportunities to increase plant safety, environmental performance. And improve uptime and availability all factors contributing to higher profitability.
The workshop will also examine scheduled maintenance and turnarounds which are opportunities to increase plant safety and environmental performance. By enhancing the mechanical integrity of HPI facilities, operating companies can achieve and maintain higher uptime and equipment availability; all are factors that contribute to higher profitability. Best-of-class companies hold the mindset that reliability programs provide great benefits. Investing in new monitoring and conditioning systems, along with preventive maintenance and inspection programs, can optimize unit and total facility performance.
The development of dry low NOx (DLN) combustors for gas turbines has cut the industry's consumption of water, while dramatically slashing air emissions. Unfortunately, this environmental enhancement has created an engineering challenge: The lean-burning DLN combustors are prone to flame instability, which can cause pressure pulsations large enough to destroy the combustor, launching debris downstream where it annihilates other hot-gas-path components. To detect and correct flame instability before it causes millions of dollars of turbine damage, savvy users have begun to install advanced sensors and robust software that monitor the combustor dynamics in real time.
High dynamics can limit hardware life and/or system operability. Thus, there have been various attempts to control combustion dynamics, to prevent degradation of system performance. There are two basic methods for controlling combustion dynamics in an industrial gas turbine combustion system: passive control and active control. As the name suggests, passive control refers to a system that incorporates certain design features and characteristics to reduce dynamic pressure oscillations. Active control, on the other hand, incorporates a sensor to detect, e.g., pressure fluctuations and to provide a feedback signal.
Which, When suitably processed by a controller, provides an input signal to a control device. The control device in turn operates to reduce the dynamic pressure oscillations. The workshop will examine the factors and the issues associated with combustor dynamics, and technologies like AMFM/CFM.

In Supercritical Power Generating Units
1. INTRODUCTION
Most power stations today are going super critical due to the immense
advantages of efficiency and their potential of lowering emissions of
carbon dioxide.
However it is now being recognized that supercritical units pose
significant chemistry challenges during the start up and commissioning
regime with consequent financial risks to EPC Contractors, who hitherto
not aware or exposed to these risks have now to adapt quickly to a new
Risk Management paradigm
2. OBJECTIVE:
To understand the risks and challenges in start up and commissioning
of supercritical power generating units and take up proper risk
management and control measures

3. Supercritical Units: Efficiency Advantage
Improvements in the efficiency of pulverized coal (P.C.) fired boiler/steam
turbine power plants have been pursued since the introduction of P.C. fired
boilers in the 1920’s.
This led eventually in the late 1960’s to the introduction of supercritical
boilers operating at about 570 Deg C (1060qF) superheat/reheat
temperatures and 24 MPa (3400 psi) pressure for the steam.
Presently boilers with 300bar and 700 Deg C are being adopted for many of
the recent power plants.
Since at these pressures and temperatures there is no distinct differences
between the water and steam phases, no drums are required in the same.

Start up chemistry guidelines should primarily focus on main steam chemistry targets,
including
cation conductivity: it warns of salts and acids that may cause turbine corrosion
silica :
silicate scaling may contribute to turbine capacity and efficiency losses.
sodium: critical for avoiding corrosion because uncontrolled sodium hydroxide
concentrations are known to cause corrosion damage failures in boiler
tubes.
Targets for chlorides, sulphates, and organic compounds should be
deferred until the end of the commissioning cycle.
Degassed cation conductivity is the preferred conductivity to be
measured during commissioning since system air leaks are still being
discovered and sealed during the start up and commissioning phase.

differentiating between air leaks and other contamination sources

The two most important parameters in Table are feed water
cation conductivity and pH.
Cation conductivity should be maintained below 0.15 µS/cm
during operation on OT. Normal pH range for feed water under
OT is 8.0 to 8.5.
The EPC contractor is challenged with controlling
pH when feed water cation conductivity increases to
concentration levels listed in Table , action levels 1,
2, and 3 (≤0.3 µS/cm, ≤0.6 µS/cm, >0.6 µS/cm,

onceThe pH/conductivity relationship is crucial for oncethrough cycles on OT; thus, the EPC contractor
implements the chemistry control at its own risk.
Important issues to be addressed when implementing OT include:
• At what point during the start up and commissioning process should the chemistry
regime be switched from AVT to OT to prevent frequent switching back and forth
between a reducing and an oxidizing environment?
• What would be the “detrimental effects” of going from an oxidizing atmosphere to a
reducing (or close to reducing) atmosphere, for temporary periods?
• How can these “detrimental effects” be quantified and addressed during design and
equipment procurement?

Stringent steam quality limits implemented by steam turbine
suppliers, boiler manufacturers have tightened limits on feed water
chemistry.
Yet EPC contractor requires standards to be relaxed during
commissioning to permit timely unit start up.
The challenge also is in determining the appropriate time to switch
from AVT to OT
Once cation conductivity levels are stable below 0.15 µS/cm,
EPRI recommends operation on OT with oxygen injection in a
pH range of 8.0 to 8.5. EPRI guidelines also state that oxygen injection
into feed water may continue with pH controlled between 9.2 and 9.6
and cation conductivity between 0.15 µS/cm and 0.3 µS/cm. However,
at cation conductivity levels greater than 0.3 µS/cm, EPRI recommends
that oxygen injection be terminated and AVT resumed. Upsets in
cation conductivity may lead to serious corrosion problems if oxygen
is continuously fed during upset conditions.
