Rowan House Ltd offers a range of training courses in Combustion and Combustion Systems. The courses offered are highlighted below.
Many processes involve the use of large quantities of heat, which is typically provided by the combustion of fossil fuels. A detailed knowledge of the principles of combustion is necessary for those involved in the design or operation of such facilities to ensure that the efficiency of operation is maximised whilst retaining the overall safety of the facility. The course covers such areas as combustion calculations, excess air and its effect upon efficiency, burners types, boilers and fired heaters, flare systems, burner management systems, emissions and their control.
The predominant type of equipment for heating of process streams in a refinery or oil and gas facility is the fired heater. These can range from the quite small to the very large and are associated directly with refinery distillation, separation and product reforming operations. The safe and efficient operation of the fired heaters has a very significant effect upon the overall refinery performance. The fired heaters consume significant quantities of fuel, whose value continues to increase in real terms, and can be involved in fires and explosions if inadequate care is taken in their design, performance and maintenance.
The course is relevant to anyone involved in the design and operation of a refinery. Topics would include types of fired heater, natural and forced draft, combustion calculations, excess air and its effect upon efficiency, burners types, tube design and material selection, types of refractory, stacks, emissions, troubleshooting, commissioning, maintenance and burner management and control.
Incineration is the destruction of waste by combustion. Incineration may be applied to gas, liquid or solid streams or indeed some combination.
The course is intended for anyone involved in, or contemplating being involved in, the incineration of waste streams. The course will include types of equipment used in incineration, emissions and their control, combustion control and excess air, the potential for heat recovery and methods for dealing with the variable properties of the waste stream and the waste products produced.
Many process facilities utilise steam as the major heating medium within heat transfer equipment on the facility. This steam is normally generated in a boiler house where fossil fuels are burnt to produce the heat for the steam production. The generated steam is often at a variety of pressures and temperatures.
The course is designed for those who operate or are responsible for the operation of such boiler facilities. The course will cover such areas as properties of saturated and superheated steam, combustion calculations, excess air and generation efficiency, types of boilers, water and steam purity, pressure reduction and desuperheating, boiler control, steam distribution and condensate recovery.
Flare and vent systems represent the last line of defence in the safe emergency disposal of unwanted products released from emergency relief or depressurisation systems. It is vitally important that the flare system is well designed and maintained to achieve safe operation under all circumstances with acceptably small environmental impact.
The course offers the design engineer faced with the task of designing or assessing the design of the flare system the necessary tools. Typical arrangements of various flare systems, identifying the purpose and importance of each component, are followed by an examination of gas combustion, air requirements, excess air and the how combustion affects emissions.
Differences between ground and elevated flares and their typical construction are explained, including the various types of elevated flare tip, together with methods of combining ground and elevated flares into an integrated system. Techniques for achieving good smokeless operation on elevated flare tips, such as air-blown, steam injected and sonic flares are reviewed and contrasted. Performance in terms of radiation, noise, emissions and utility requirements are identified together with their effects upon personnel and adjacent facilities.
Liquid knockout facilities are examined and appropriate system requirements identified to prevent liquid carryover to the flare. Seal pot systems, often used in flare staging, are considered and alternative methods of providing and disposing of the seal water are compared. Systems for flare gas recovery are examined and types of compressor are compared. The need for elevated flare stack purging is considered and alternative approaches using fuel and inert gases are compared. At each stage of the course, recommendations regarding essential maintenance and repair of the components of the flare system will be developed. Throughout the course the relevant contents of established specifications for flare systems, such as API 520 and API 521, are developed and related to the balance of the course content.
The timely completion of the commissioning process is often crucial in process plant development and this course aims to help the commissioning manager to achieve the desired result. It starts by looking at critical design stages, such as HAZOP’s and commissioning plans, and identifies where and how commissioning considerations should be included.
The organisation of the commissioning team is reviewed along with the necessary support functions together with an analysis of commissioning strategy and causes of problems and outages.
A review follows of pre-commissioning activities, such as integrity checking, flushing and cleaning and pre-operational checks with conclusions recorded on punch lists and this is extended to cover a range of equipment including vessels, rotating machinery, and instrumentation, control and electrical.
Safety and accident prevention is of primary importance in all these activities and this is stressed throughout the course with sessions on job safety analysis, risk assessment and safety reviews.
Finally the course examines trouble-shooting and problem-solving approaches, looking at methods of testing hypotheses and avoiding expensive solutions.
