(57) Abstract:

The inventive combustion system in steam boilers polluted waters, including high-viscosity oil residues, contains the fuel pump 2, which is communicated with the fuel tank 1 and the consumer, and the ejector 3, the nozzle which is connected to the pressure connection of the pump 2, and the outlet with a reception pipe of the pump. The suction nozzle of the ejector 3 is in communication with the flexible hose 4, which is communicated with a capacity of 9 collection of oil-contaminated waters. Flexible hose 4 at the free end has a receiving filter 5 and is supported on the surface of the water floating device 6. The tank 9 is supplied by the device 7 of the heated surface layer with thermal relay 8. 1 C.p. f-crystals, 1 Il.

The invention relates to the use boilers of power plants, such as stationary, and can be used in the operation of the ship steam boilers running on liquid petroleum low-grade fuel.

A device for cleaning inner-bottom ballast compartments from the bottom sediments, including cargo, fuel pump, at the end of the discharge nozzle which is installed ejector, suction pipe which is placed at the bottom is Titkov, especially at low temperatures, and collected sediment doing in the fuel tank, dramatically degrade the quality of fuel used.

A device for Stripping vessel inner-bottom compartments, including a wiper pump, piping, valves, collecting tank, dirty fuel, floating funnel and a flexible element [2]

The device collects the oil film from the surface of contaminated water, essentially not providing recycling water with a lower oil-bearing, i.e. the lower layers of water, and the collection of high-viscosity oil residues due to their high viscosity at temperatures below 24aboutC.

The device has a number of fundamental flaws. In particular, does not ensure the environmental safety of power plants by burning the collected oil burning oily water in the fuel composition of the emulsion and reduce gas and thermal pollution. The device has a significant mass-dimensional characteristics and requires additional volume for placement of elements.

Closest to the proposed system is a combustion in steam boilers polluted waters, vkluchaysya tank, and pressure with the consumer, and the ejector nozzle which is connected to the pressure connection of the pump, and the outlet with a reception pipe of the pump, and the suction nozzle of the ejector equipped suction pipe communicated with the collection vessel of oil-contaminated water [3]

However, this system is environmentally hazardous, does not solve the problem of utilization in steam boilers viscous oil residue. Technologically specified is caused by the fact that the system is not structurally provides suction for viscous oil residue when the outside temperature is below 24-25aboutWith due solidification intake of refined petroleum products. The inability to suction at a given temperature is determined by the absence in the system device for heating the oil layer.

The aim of the invention is to increase the environmental safety of boilers by burning high-viscosity oil residues and disposal of contaminated water in the composition of the water fuel emulsion.

For this purpose, the suction pipe of the ejector is made in the form of a flexible hose with an acceptance filter, placed at the level of the contaminated oil the surface layer of the water and supported the Jena device warming of these waters.

In addition, the floating device includes at least one float or pontoon, is fixed on the flexible hose with connections, mainly holodovogo, and the device is heated waters contaminated with oil products made with thermal relay, connected to its heating element.

The drawing shows the proposed system, the overall look.

System combustion in steam boilers polluted waters, including high-viscosity oil residues, contains the fuel tank 1, the fuel pump 2, the ejector 3, the suction flexible hose 4 with the receiving filter 5, the floating device 6, device 7 of the heated surface layer with thermal relay 8 and the capacity of the 9 collection of oil-contaminated waters.

The system works as follows.

During operation of the fuel pump 2 fuel is drawn from tank 1 and under pressure to the ejector 3, where the vacuum is created. Contaminated with oil, water, preheated to a temperature of 50-70aboutWith the capacity of 9 collect contaminated water sucked through the suction filter 5 and through a flexible hose 4 is fed into the working cavity of the ejector 3, where, mixing with the fuel, forms a water fuel emulsion, padave the filter 5 floats on the surface of the water in the tank 9 collection of polluted water. In case of changing the thickness of the superficial oily layer floating device 6 is manually moved along the length of the hose 4 and the receiving filter 5 is buried (or floats). Surface oil layer is heated to a temperature of 50-70aboutWith using the heating element of the heating device 7. At temperatures below the 50aboutWith thermal relay 8 engages the heating element device 7, and at temperatures above 70aboutWith off the heating element.

SYSTEM COMBUSTION IN STEAM BOILERS POLLUTED WATERS, including high-viscosity residual oil containing fuel pump, inlet pipe which is communicated with the fuel tank and the pressure with the consumer, and the ejector nozzle which is connected to the pressure connection of the pump, and the outlet with a reception pipe of the pump, and the suction nozzle of the ejector equipped suction pipe communicated with the collection vessel of oil-contaminated waters, characterized in that the suction pipe of the ejector is made in the form of a flexible hose with an acceptance filter, posted by on the level contaminated with oil products surface layer of water and maintained at this level by using plavuse="ptx2">

2. The system under item 1, characterized in that the floating device includes at least one float or pontoon, is fixed on the flexible hose with connections, mainly holodovogo, and the device is heated waters contaminated with oil products made with thermal relay, connected to its heating element.
