The invention relates to devices for burning cleaning materials and debris and can be used on sea and river vessels of all types and structures, as well as enterprises in which such waste is generated.

The purpose of the invention is to simplify the design and increase fire safety.

The drawing shows a ship incinerator.

The furnace contains an outer casing 1 with an insulating coating 2 and with air holes 3 placed in the upper part of the casing 1, an ashpit 4 with a nozzle 5 for removing ash and a clean room 6, once it has been installed, a boiling point 7, a chamber 8 Combustion by grates 9 and a lid 10 for barrels and waste, air supply channel 11, in,. an ejector 12 with a movable diffuser 13 and a nozzle device 14, a drain 15 ejector and a drain pipe1) gadfly 16.

Combustion chamber 8 B1 is full in the form of coarse with spikelets from the banded section .1 and p its lower part, and in the upper part it is connected to a hermetic cover K) for waste loading and vertically installed. which forms an air supplying cap. l. between the outer casing of the combustion chamber and the inside of the outer casing of the furnace. In the upper part of the furnace, the air intake duct is connected to the suction inlets through which the water ejector draws in the fresh air necessary for burning the waste, which, as it passes through the air inlet duct, is an insulator between the outer casing and the combustion chamber. The outer casing, covered with a Yum-m layer of asbestos, has an outside coating temperature not exceeding the allowable temperature for outdoor hot surfaces.

The passage between the two furnace bodies, the air heats up and enters the combustion chamber, which contributes to the improvement of waste incineration.

The vertical location of the combustion chamber is advisable, since the process of burning waste occurs in its lower part, the ash and ash formed are poured into the ashpit, and smoke, passage of the upper layers of waste formed from the combustion of waste, is partially filtered and warms them up, preparing for burning.

The destruction of waste in the combustion chamber occurs due to the smoldering of waste under the influence of a stream of fresh hot air entering the lower part of the combustion chamber through the grate through the air inlet duct due to the thrust created by the water ejector.

The latter, moreover, performs the role of a mixer, mixing the smoke with incoming working water during the furnace operation, ensuring that it dissolves completely in its diffuser and smokelessly destroys waste, lack of sparking and gas exhaust lines, which simplifies the design ovens. The water ejector also provides the ability to adjust the temperature of the furnace by moving the diffuser relative to the axis. By increasing or decreasing the distance from the nozzle to the mouth of the diffuser and thereby changing the efficiency of the ejector, and consequently the amount of air supplied to the combustion chamber, you can choose any necessary waste disposal dianazone acceptable for specific conditions, reduce the amount of ignition and load baking waste without stopping it as it accumulates during the working day.

Installing a water ejector opens up the possibility of unloading the furnace (removing waste products of the combustion that are in the ashpit) by supplying working water from the ejector to the combustion chamber and provides the possibility of stopping the process of burning waste in the furnace at any time.

The furnace works as follows.

The waste is loaded into the combustion chamber 8 through the neck of the lid 10, which is hermetically closed. The working water is supplied to the water ejector 12. Then the waste is ignited manually through the hatch 7 or automatically by an electric arc. Due to this, created by the water ejector 12, the process of smoldering of waste in the lower part of the combustion chamber 8 begins. Fresh air required for incineration of waste is sucked in by a water ejector 12 through openings 3 located around the circumference in the upper part of housing 1. The smoke from the corrosive waste is rising, rising up due to the thrust created by the water ejector 12, and the passage The upper layers of the waste in the combustion chamber 8 are partially filtered through them, coming to the suction head, to it the ejector pipe 12, where in its movable diffuser 13, and later in the discharge pipe 16 is mixed with the working water supplied to the water ejector 12. When mixing the smoke Water is completely absorbed, as a result of which spark and smoke are completely absent. As the lower layers of the waste are burned, the ash and ashes formed from them are poured into the ash pan 4, and the upper layers of the waste are dipped into the bottom of the combustion chamber 8 under the action of their weight.

After stopping the operation of the furnace, the unloading blade 6 is installed, installed at the bottom of the ashpit 4, and the discharge valve 15 of the water ejector 12 is closed. Due to this, the working water supplied to the water ejector 12 through its nozzle device 14 flows under pressure into the combustion chamber 8, washing away soot and ash from it. The installation is again ready for operation.

The invention allows to simplify the design of the furnace due to the absence of a complex refractory lining of the outer casing, to carry out the destruction of waste by smoldering without the use of open fire due to the thrust generated by the ejector, to increase fire safety due to the absence of venting channels and the gas duct.

The ship furnace of this design can be operated as a scrapper without installing a special ejector pump, i.e., water from the cooling system of the main and auxiliary mechanisms permanently operating on the vessel is used. The small size, fire safety and independence from the operation of any ship machinery allows the furnace to be installed practically in any place on the ship, regardless of the type of vessels, structures and year of commissioning.

 The ship's stove can be made both stationary and portable (for example, a portable stove can be installed on the main deck, and working water can be supplied from the fire main).
