Description

The invention relates to an oil furnace for the heat treatment of metals with a combustion chamber located directly in the gum area and with a heated flue gas and exhaust.

In the proposed naphtha furnace, the combustion chamber is divided into two parts and is equipped with auxiliary roof canopies for guiding the flame along the upper arches and its whirl.

In FIG. 1 shows a petroleum furnace in a perspective view; FIG. 2-4 vertical cuts of the furnace; FIG. 5 is a section along the line AB in FIG. 2; FIG. b-section along the line of the LED in FIG. 3, and FIG. 7 is a section along the EF line in FIG. four.

The proposed oil for the furnace consists of the combustion chamber A, the working space B and the exhaust gas chamber c.

In order to uniformly warm the working space B, combustion chamber A is divided by a rammer / into two independent chambers, each of which is heated by a separate nozzle 2. In the combustion chambers, opposite arches are installed.

the upper vaults, which swirl it against the opposite walls and thereby create some pressure in the combustion chamber, contributing to a smooth, velocity and uniform over the entire surface outlet to the working space B of gases through the apertures of the lower arch. From the side of the combustion chamber, the working space 5 has openings with a small diameter, which contributes to complete combustion and, when operating, only completely colorless red-hot gases enter the working chamber. The space between the arches 3 and 5 is divided by partitions 4, which cause the exhaust gases to go to work. whose space is uniform throughout the arch. Upper arches 6 go; g each independently, according to its peak.

To warm up the bottom 7 of the working space, the gases are fed by four opposite channels 8, into the waste gas chamber C, where the longitudinal bridges 9 are sent to the front wall of the furnace, by heating the bottom sides of the hearth, then by the middle channel to the rear wall of the furnace and exit into the chimney. The opening of the chimney is closed with a flap / 2, which serves to control the flow of gases to the chimney. When distributing, the chimney is fully opened by means of the grip 75 and as the furnace heats up, it is closed with a flap. When a colorless gas appears through the openings of the roof, the chimney is closed to the maximum position, which allows the minimum gas flow, which reduces the pressure in the working space of the furnace. In order to use the heat of exhaust gases, for the sake of fuel economy, in chamber G there are heaters / O air in the lateral passages, and oil on average 77 in the heater.

Air preheaters consist of a reservoir through which the air passes from the factory pneumatic trunk, equipped with a blow-off tap, which serves to release water. At the dead end of the middle compartment on the rear wall there is a coil - oil heater 77, protected from direct exposure to hot gases by a brick wall 14 that reflects gases

straight into the chimney. The processes from the air and oil heaters go to the nozzles 2 outside the furnace, where they are closed with insulating shells.

The furnace is located on the appropriate foundation. The entire path of flame and hot gases is lined with refractory bricks. The brickwork of the furnace, made of ordinary building brick, is enclosed in an iron casing 75, reinforced with channels.

The loading opening is closed by a door 16 of the usual type of counterbalance for metallurgical furnaces 77.

The subject matter of the invention.

 Oil for the heat treatment of metals with a combustion chamber located directly above the working space and heated waste with scimi gasses, characterized in that the bridge 7 divided into two parts 1 and heated bilaterally by nozzles 2 is equipped with combustion canal A to guide the flame along the upper vaults and its swirling, auxiliary arches-canopies 5,
