PyroWater utilizer is based on two eminent technologies – Emulsion and Atomization. Emulsion is a process where oil and water are mixed to form and maintain a temporary suspension by reducing their particulate sizes. The suspension goes back over time to initial two-phase system where the materials separately exist as immiscible. The rate at which the emulsion returns to phase separation depends on types, viscosities, particulate size and composition of mixed materials and the temperature. Specifically, smaller particulate sizes, desirably reduced to submicron level, tend to help keep the liquid emulsified for a longer period.
Pyro Water Utilizer creates special condition for waste water which turns it into an efficient emulsion fuel. With a pH value of about 9.5, waste water is mainly a mixture of water and oil in ready-to-emulsify state. As it is widely known, high pH value provides for a better emulsion platform. In addition to this the inorganic constituents further enhance the emulsion process as they possess the quality of a surfactant. With the help of a high shear mixer, which creates different velocities throughout the water, and pressure in the fluid, water molecules and other constituents breakup in to smaller particles. This results in a stable and homogeneous nanoemulsion, good enough to be utilized within the period of process of Pyro Water Utilizer.
On reaching its emulsified stage, pyro water is sprayed into the burner. When air or required gas is injected through a tube with decreasing section, it speeds up generating a pressure drop at the narrowest point. While the dispersion is fairly viscous it still flows readily and does not have to be heated prior to supplying it to the burner. This is one of the advantages of the present invention as it permits eliminating heating equipment without eliminating its function. Then the gas/air combines with the liquid to provide a more readily combustible aerosol. Due to the increase in temperature, the water molecules further lose their viscosity and surface tension increasing the diffusion. Additionally this causes the rapid expansion and fragmentation of oil droplets, a process known as secondary atomization. The flame thermal energy reduces the aerosol completely to release energy, completing the process of atomization.
In comparison to wood and coal, waste water fuel has a lower flash point. Further waste water fuel burns at much lower temperatures. The waste water that is not fully combustible even at 1000℃,completely burns at even 600℃ with much lower emissions. Added to this usage of wood is reduced substantially. Low Temperature Combustion (LTC) is a reference to advance combustion concepts with the overall goal to reduce and/or alter advantageously NOX and soot formation.
Thus, PyroWater Utilizer not only eliminates the problems of disposal but also converts the waste water into useful energy.
