Low temp monotube boiler design

Low temp monotube boiler design

Low temp monotube boiler design

(OP)
I am constructing a hybrid solar/ solid fuel generator system. An insulated water tank will evaporate R134a, in a coil(s) configuration,always below the boiling point of water open to the atmosphere for safetys sake. The vapor will drive one or more rotary vane a/c compressors modified as expanders then be condensed and returned to the tank. My questions are:
1) How do I control the feedpump to maintain the proper amount of fluid in the monotube coil(s) according to variable demands for power?
2) Is there a particular design feature of the coil needed to prevent slugging and facilitate evacuation of accumulated refrigerant oil in the coil(s)
Thanks
