Thermal fluid systems require no blowdown, and unlike steam systems, are not subject to continual leakage. Should Paratherm fluids escape from the system, cleanup is handled using the same simple procedures followed for spills of light lubricating oil. And unlike heavily treated boiler feed water, Paratherm heat transfer fluids offer safe, easy

under specific heat transfer conditions. Therminol 66 has made its reputation for its outstanding stability in operation. Fluid decomposition, both for mineral oil and synthetic hydrocar-bon based heat transfer fluids, generally results in the formation of (high boilers).

Boiler ash is recycled as fertilizer and factory floor cleaning agent. The potash in the ashes reacts with the oil to form a weak potash soap that is washed away with water. Small-scale mills also use the fibre and bunch waste as fuel material.

Just as coal-fired boilers are not designed in the same way as oil- or gas-fired boilers, neither can biomass-fired boilers be designed as coal-fired boilers, if they are to function efficiently. Biomass firing requires a larger furnace (i.e. a larger radiation heat transfer surface) than coal firing.

Boilers are used in power plants in order to produce high pressured steam, so that the plant can generate electricity.The process that does this is known as the Rankine cycle.The boiler takes in energy from some form of fuel such as coal, natural gas, or nuclear fuel to heat water into steam..

Large heat exchanger surface required for heat transfer; since low temperature waste heat will involve a smaller temperature gradient between two fluid streams, larger surface areas are required for heat transfer. This limits the economy of heat exchangers.
