Designation and the field of application
Device on the preparation at the point of the
combustion of the irrigated petroleum residue (disperser, cavitator) - the
passive device (without moving parts and power supply), which consists
besides flow area with the located before it stimulators of the process of
cavitation.
As a result [kavitatsiionnoy] working of initial
water-mazut mixture occurs its conversion beside the homogeneous, highly
stable and fine dispersed water-mazut emulsion, which is not divided into
layers for a long time (not less than the year), that preserves its
properties after storage at minus temperatures, which cause the freezing of
water before the fuel, and having during the combustion higher energy and
ecological characteristics.
For the preparation of water-mazut emulsion can
be used [zagryaznennye] by the petroleum products of water, and also the
water, which is contained before the commodity petroleum residue. The
proposed device is past testing and successfully it works before power units
and boiler rooms of different designation. The results of operation show
that the use of a cavitator is allowed:
1. in the region of increasing the
reliability of the boilers
1. to guarantee the reliable work of boilers
during the irrigation of initial fuel to 30%.
2. to form steady torch and to decrease its
length, to thus decrease the temperature of combustion products against the
output based on the furnace and the low-temperature sulfuric acid corrosion
of equipment.
3. to increase the combustion efficiency of fuel
and to decrease the deposits of the [nedosgorevshego] fuel before the gas
circuit and beyond the surfaces of air heater.
2. in the region of increasing the efficiency
1. to obtain additional energy due to an
increase in the combustion efficiency of fuel and utilization of the
petroleum products, which are contained before the waste liquids.
2. to use the cheaper [obvodnennye] or sulfurous
petroleum residue and thus to save to 10% of cash resources due to the
substitution of stove fuel.
3. to decrease the means, expended for averting
of the pollution of natural medium.
3. in the field of the ecology
1. to liquidate cancerogenic substances and to
decrease the content Of n[O]x as far as 20-40%, benzo (A) pyrene down
50-100%.
2. to attain the complete combustion of carbon
monoxide BASED ON the soot, and to also decrease the concentration SO3
during the combustion of sulfurous petroleum residue.
Technical and economic

- payback period with the
complete load of cavitator, mo., is not more than 4
- fuel economy - 3-5%
- an increase efficiency in
the boiler - 2-3%
- an increase in the period
of the service of boiler equipment - to 40%
- reduction in the harmful
ejections - 70-80%
- the exception of the
disruption of torch with the water contaminability of petroleum residue - to
30%
- the savings of means due
to the use of cheaper types of the petroleum residue
([s])
development is protected by patents.
