SU89342A1 - Constructing a steelmaking recuperative furnace with a constant flame direction - Google Patents

Description

.M YAHZAE daoo 18b. 5D4SSD in the DESCRIPTION OF THE INVENTION It does not allow you to easily adjust the repair of stoves without stopping the stove, and does not guarantee the necessary heat transfer and resistance of the stove. To eliminate the above disadvantages, it is proposed to Blow from Golyuvkam with both fenders, ensuring that the furnace produces in the furnace the horseshoe-shaped forks of the constant direction of the VCC during the simultaneous operation of both heads, and when they work in turns or when one head is working on liquid or gaseous fuel, both atmospheric and and oxygen-enriched air and x-calorie or low-calorie gas. A horseshoe-shaped flame of constant direction in a vertical angle is achieved by forming a passage over the air head. and removing combustion products from the working and tsrootrano1 through "the pass n through two adjoining channel vertikadnnh vozdushshy channels on each side of the furnace. In the air-inclined KBHfljB heads; berth for heating the air supplied to the furnace, ceramics g -. - - - .g ...

Scale revupertorn, recruited from shaped chamotte virchgaa It is advisable that two or three upper ones be pleased to collect willows of shaped aound bricks and catch them with the outer air, in particular, it is possible to run the furnace using the rekterator dd gas heating unit, installed in ceramics.

In addition to this, the furnace's head, in order to form an ovane in a horseshoe-shaped pattern, was able to find out how to do it, not only in a vertical, but in a horizontal box, and with the help of a significant hHU, the curvature of the curvature is given to the products of combustion above the slope of the patterns and the pattern of smoke. Treat the burning dd products.

In the proposed device, the use of slags is a mess to remove the wigak in a visible state, including slag shears used in tone.

On, fig.I presents a longitudinal section opionova oven; at .2 ° its cross section.

The vertical plane passing through the center of the melting space divides the furnace into two equal parts, pa, boiling, as if it were, at the same time. Through the inclined channel of the head I enters the air from the heat exchanger 2, the heated Thai to. Using an injector 3, fuel is introduced into this channel. The sprayed fuel stream designs hot air, reducing the required air pressure before the recuperator.

Flows of combustion products entering the melting space 4 from both working heads meet in the center of the melting space turning and returning to the heads, from where they enter the slags of the usual construction through two vertical channels with each side of the furnace, then into the heat recovery units. Reheaters are two, one on each side. Recuperators are ceramic, such as Azovstal plant blocking wells. The products of combustion along the vertical channels of the heat exchanger move from top to bottom. This arrangement of smoke channels facilitates their cleaning.

The air moves in a zigzag manner in the space between the pipes of the recuperator and then through the collecting duct 5 is directed into the inclined air channel of the head.

Recuperato made rto willows of shaped shamoyumgo bricks for the exception of two or three upper rows, secondly alyundovshishsh.

A crown of that, under the top of the river, the 6th class, his best ohdakdvka is supplied with cold air,

The products of combustion of both heat exchangers are oi $ ase. Koteot and sent to the bottom; n pipe.

Two variants of stoves are installed: chiro-iagvevitkovy and dsha-ovna. In the mainstream, the main gadfly, gadfly of heads, oteakk vert of the main canals and Evlakovshsi vvodvvavvtov y. chrono-heaaaaa-ego in the nugget bricks, VO-the second - I8 of the virgin kirschpa.

In turn, necro in the Diano version, in turn, appeared in 7 (2 types). In the first case, the shyhod for the products that are above the air duct of the head is significantly reduced compared to the Ho-416 version, as a result of which the gases in the melting space are rotated not only in the helicopter plane, but also, to a large extent, in the horizontal plane, and the product of combustion passes through the aisles on both sides of the inclined smut air channel.

This greatly facilitates the work of the main arch.

In the second variant, the combustion shields in the floating space are rotated in the horizontal plane, and the removal is exclusively through the aisles from both sides of the air channel of the head. The air channel of the head is made to extend to the melting area, as a result of which a portion of the air can flow to the roof, while the latter is the last.

However, it should be noted that a sharp improvement in the work of the vault in the second variant is achieved due to some deterioration in the conditions of service of the walls.
