Abstract
A dual heating process is performed in the absence of an open flame. Heat is created by a rotating prime mover(s) driving a fluid shear heater. Heat is also collected from a cooling system of the prime mover, and from any exhaust heat generated by the prime mover. The heat energy collected from all of these sources is transmitted through heat exchangers to a fluid where heat energy is desired. The fluid being heated may be glycol or air, depending on the type of heat desired.
Claims40
A flameless combination heater for heating air and a heater fluid, the flameless combination heater comprising:
- a prime mover system including an engine, an intercooler and at least one heat removal means;
- an air moving system;
- and
- a heater fluid system comprising:
- heater fluid;
- a first heat exchanger configured to transfer heat from one of the at least one heat removal means to the heater fluid;
- a dynamic heater in fluid communication with the first heat exchanger for heating the heater fluid, the dynamic heater driven by the prime mover system;
- a second heat exchanger configured to transfer heat from the heater fluid to air in the air moving system, the air moving system configured to permit transfer of heat from the intercooler to the air in the air moving system;
- and
- a variable valve configured to direct a first portion of heater fluid received from the dynamic heater to the second heat exchanger via a first pipeline and to direct a remaining second portion of the heater fluid received from the dynamic heater to a heater fluid heat output via a second pipeline.
A flameless combination heater for heating air and a heater fluid, the flameless combination heater comprising:
- a prime mover system including an engine, circulating engine coolant and an intercooler;
- and
- a closed heater fluid system comprising:
- a heater fluid reservoir;
- a pump configured to pump heater fluid from the reservoir to a first heat exchanger, the first heat exchanger configured to transfer heat from the engine coolant to the heater fluid;
- a dynamic heater configured to heat heater fluid received from the first heat exchanger;
- and
- a variable valve configured to regulate distribution of the heater fluid from the dynamic heater between a heater fluid output means of the flameless combination heater and a second heat exchanger for heating air for output by the flameless combination heater, the air for output being heatable by at least the second heat exchanger and the intercooler.
A method for heating a heater fluid and air using a flameless heating system, the flameless heating system comprising a dynamic heater driven by a prime mover including an engine, the method comprising:
- transferring the heater fluid through a first heat exchanger transferring heat from engine coolant circulating through the prime mover to the heater fluid;
- transferring the heater fluid from the first heat exchanger through the dynamic heater to further transfer heat from the dynamic heater to the heater fluid;
- directing, via a variable valve, a first portion of the heater fluid from the dynamic heater to a second heat exchanger via a first pipeline,
- directing, via the variable valve, a remaining second portion of the heater fluid received from the dynamic heater providing a first heat output of the flameless heating system via a second pipeline;
- and
- heating air using the second heat exchanger and an intercooler of the prime mover, the heated air providing a second heat output of the flameless heating system.
A method for heating a heater fluid and air using a flameless heating system, the flameless heating system comprising a dynamic heater driven by a prime mover including an engine, the method comprising:
- heating the heater fluid using:
- the dynamic heater;
- a first heat exchanger transferring heat removed from the prime mover while driving the dynamic heater to the heater fluid;
- and then
- directing, via a variable valve, a first portion of the heater fluid thus heated to a second heat exchanger for heating air, the air also being heated by an intercooler of the prime mover, the heated air thus providing a heat output of the flameless heating system, and
- directing, via the variable valve, a remaining second portion of the heater fluid thus heated providing another heat output of the flameless heating system.
