Fuel is exchanger that recovers heat from a burned inside the furnace, creating hot hot gas stream, usually coming from gas which heats water in the steam- gas turbine or engines. It produces generating tubes. steam that can be used in a process The heated water then rises into the (cogeneration) or used to drive a steam steam drum. Here, saturated steam turbine (combined cycle). is drawn off the top of the drum. In HRSGs consist of four major some services (power generation), the components: the economizer, steam will reenter the furnace through evaporator, superheater and water a superheater to become superheated. preheater. The different components Superheated steam is a dry gas and are put together to meet the operating therefore used to drive turbines to requirements of the unit. produce electric energy by generator. Modular HRSGs can be categorized by a number of ways such as direction A fire-tube boiler is a type of boiler of exhaust gases flow or number of in which hot gases from a fire pass pressure levels. through one or more tubes running through a sealed container of water. The HRSGs systems could be of two The heat of the gases is transferred type: one, where gas turbine is coupled through the walls of the tubes by directly to the steam generator and thermal conduction, heating the water the major components are disposed and ultimately creating steam. in line: superheater, evaporator and Such boilers are usually used where economizer (one pressure level); this is are not requested high power and the typical application of our burners sometimes are preferred to water “DB” type, which are installed inside tube boiler thanks to their simpler the duct that connects gas turbine and configuration. steam generator. The other type is a classic steam generator: the exhaust Steam boilers are the typical gas coming from gas turbine reaches applications of our “M”, “DM” and “DT” the burners, which are installed on burners type which are designed and boiler front wall. This is the typical offered according to the emission application of our burners “M” or “DM” levels required and fuels to be burn. type, adapted for such application. In both cases the burner are suitable to work either with hot flue gas stream or fresh air. 8 APPLICATION Waste to Energy Systems Depending from incinerator’s characteristics and Client’s request we Waste-to-energy (WTE) is the process are able to design such combustion of generating energy in the form system complete with all ancillaries of electricity and/or heat from the equipment (combustion air fan, oil incineration of waste. WTE is a form of & gas skids and so on) and control energy recovery. Most WTE processes system. Usually, for the above produce electricity and/or heat directly application, we use “M” or “DM” burners through combustion. type. Incineration, the combustion of Heaters and Furnaces organic material such as waste with energy recovery, is the most In the industrial world are present a common WTE implementation. The huge range of industrial heaters and combustion of waste may produce process furnaces, which are necessary many pollutants that must be treated in various processes related to and reduced before the stack, to avoid refineries, gaseous and liquid streams environmental contamination. treatment or to metallurgical industry. In such systems is necessary to have a We are capable to supply some of its combustion system properly designed: products suitable for applications like the role of the burner (or burners) air heaters, gas heaters, blast furnaces, is to heat up the furnace and the water bath heaters or glycol reboiler, combustion chamber during the start- kiln processes, refinery processes as up phases until a temperature suitable cracking or reforming, and particular for the introduction of waste and the burners for sulphur, installed on maintenance of the flame stability sulphuric acid production plants. by the same. Once the combustion chamber has reached the correct working temperature, the burner is moved in stand-by position and protected from the flame and flue acid gas generated by waste combustion. The burner will return in firing position only if the temperature in combustion chamber reaches the limits imposed by law, or to shut-down the incinerator. 9 SERVICES ELCO is close to its Customers and, Training of local personnel for this reason, is important for us to Our engineers will transfer their give all the necessary support, efficient knowledge, thanks to a long and quick, whenever is necessary. Our experience, to Client’s employees, for a service team personnel have a lot of correct maintenance and management experience in field application and of the combustion system. work closely with our technical offices in order to provide the best solution Evaluation and Revamping at your problems. We could provide a Our company has the capabilities to lot of services from consulting, presale evaluate your combustion system and after sale. and all the equipment installed to support the process i.e. valve Start-up and Commissioning and instrumentation train, burner Assistance management system, combustion air Working closely to power plant distribution, control system and so on manufacturer we are usually called in order to provide technical service to to start-up our combustion system, upgrade your system. A written relation and tuning our burners into the best with technical solutions, which enable configuration, which give to Client the our Client to choose the best way to best performance in terms of emission act, basing on its needs and financial levels and combustion efficiency. possibilities, usually follows such activities. 10 SERVICES CFD The company can provide support even for CFD (Computational Fluid Dynamics) studies; the CFD can be applied to many situations and applications and we usually provide such service to study the combustion air and flue gas mixing in application with FGR (Flue Gas Recirculation), to study the air distribution inside the burner and the flame shape and distribution, and to study the exhaust gas distribution to the burners coming from gas turbine in Heat Recovery Steam Generators in order to optimize the distribution, the emissions levels and to prevent backfires on the burners. 11 REVAMPING The company can provide a technical, competent and adequate support for revamping and retrofitting activities, in particular concerning the replacement of an old and obsolete combustion system with a new one in order to increase the safety, the performances and reach low emissions levels according to the local regulation and to optimize the combustion and increase the efficiency of the system. A really good interaction between our commercial and technical departments permits us to follow the client from the first evaluation activities and feasibility studies till the
