At the heart of what Frank Lill and Son does is installations:

Heat Recovery Steam Generators (HRSG). An HRSG is a heat exchanger that recovers heat from a hot gas stream. It produces steam that can be used in a process or used to drive a steam turbine. A common application for an HRSG is in a combined-cycle power station, where hot exhaust from a gas turbine is fed to an HRSG to generate steam which in turn drives a steam turbine. This combination produces electricity more efficiently than either the gas turbine or steam turbine alone.
Refuse Derived Fuel (RDF) units. Refuse-derived fuel or solid recovered fuel/ specified recovered fuel (SRF) is a fuel produced by shredding municipal solid waste (MSW) or steam pressure treating in an autoclave. RDF consists largely of organic components of municipal waste such as plastics and biodegradable waste. RDF processing facilities are normally located near a source of MSW and, while an optional combustion facility is normally close to the processing facility, it may also be located at a remote location.
Flue-Gas Desulfurization (FGD) systems. Flue gas desulfurization is the technology used for removing sulfur dioxide (SO2) from the exhaust flue gases in power plants that burn coal or oil to produce steam for the steam turbines that drive their electricity generators. Sulfur dioxide is responsible for acid rain formation. Tall flue gas stacks disperse the emissions by diluting the pollutants in ambient air and transporting them to other regions.For a typical coal-fired power station, FGD will remove 95 percent or more of the SO2 in the flue gases.
Selective Catalyst Reduction (SCR) systems. Selective catalytic reduction is a means of converting nitrogen oxides, also referred to as NOx with the aid of a catalyst into diatomic nitrogen, N2, and water, H2O. A gaseous reductant, typically anhydrous ammonia, aqueous ammonia or urea, is added to a stream of flue or exhaust gas and is absorbed onto a catalyst. Carbon dioxide, CO2 is a reaction product when urea is used as the reductant. Commercial selective catalytic reduction systems are typically found on large utility boilers, industrial boilers, and municipal solid waste boilers and have been shown to reduce NOx from 70-95%.

By keeping pace with technological advancements, we are able to handle such major projects as:

Cogeneration plants.
Turbine installations.
Sophisticated pollution control system installations.
Field-erected steel tanks, conveyors, and material handling facilities.
Installation and testing of computerized direct-digital control systems.
Complete solid and liquid fluid handling systems.

Frank Lill and Son maintains its own in-house Safety Program, which has been instrumental in allowing us to maintain our excellent safety rating.
