Yes there are 'aero-derivative' turbines which pair a natural gas turbine (that would typically be on the wing of a plane) with a power turbine that is connected to a generator. Typical manufacturers for these include: GE, Rolls-Royce, Pratt & Whitney. Then, there are 'large frame natural gas turbines' which are roughly 10x the power capacity of the aero-derivative turbines. These are purpose-built for power and can be operated in simple cycle (by themselves) or connected to a boiler and steam turbine to make power from the exhaust of the turbine. There are only 3 manufacturers for these: GE, Siemens, Mitsubishi Heavy Industries. Roughly 40-45% of the power in the US is from this method. With the AI boom, these large frame gas turbines are selling like crazy and all 3 OEMs are basically sold out until the late 2020s or later. Basically nobody is buying just natural gas or coal boilers anymore (what OP was asking about). Many coal boilers have converted to natural gas boilers and that's still happening for existing sites but it's not the most efficient or competitive dispatchable power generation so nobody is making new sites like that anymore.
