JPS58201890A - Continuous process for water gas reaction of carbonaceous substance in down draft cupola fire chamber - Google Patents

Abstract

PURPOSE:Piled layers of coke and calcite are built up in a down draft cupola fire chamber and the incomplete combustion of carbon-containing substance is effected on the layer surface or in the layers and steam is made to act on the formed fire dusts to permit continuous water gas reaction. CONSTITUTION:Piled layers of coke and/or calcite RC are built up in the down draft cupola fire chamber F and incomplete combustion of carbon-containing substance is effected on the layer surface or in the layers. Then, 1mol of steam is made to the fire dusts formed by the reaction: 3C+O2 to effect the reactions of equations I and II (Qa is the heat of formation of CO).

Description

Detailed Description of the Invention The firebox F refers to the large-diameter cylinder in the upper part of the packed bed (J)K in Fig. 1 (Patent No. 905970), and the lower large-diameter cylinder is referred to as the flue corridor Ro (Patent No. 90). .5.968/No. 1037503
(No.).

F is a water gasification continuous reaction site, and the lower part of PK is set at 1000 to 1200°C, which is the condition for A phenomenon to occur.

First, the second solid solution experiment example: SO2 of incomplete combustion of old tires at F
Is the oxidizing atmosphere of steam injected into the soot and smoke sparks? It became smokeless by blowing up → The lower iron plate of the PK was melted (: At the lower part of the PK)
Furnace A temperature increased to 1600°C - reversal phenomenon occurred); When we tried to stop the steam, soot leaked into Ro → Steam is the most effective material for smoke elimination.

Phenomenon A is caused by the temperature rise of umbrella-shaped deposits of C at the bottom of the PK → powdered coal becomes F.
If the air is blown up, the A phenomenon becomes noticeable (51.1 k.
;-1098'3) C becomes an instantaneous reducing agent that can raise the temperature to >2500°C in rcO-1200°C with the red heat of the residual Q when half of Qa is transferred to CO production.

A large amount of CO atmosphere remains on the floor.

A large amount of C of the hydrocarbon CnH2n++ accumulates on the RC bed surface when flowing downward through an incomplete combustion flame with an oxygen number Onn in 2 limestone Rc. The continuous conditions for causing blown-up steam to act on the Sm space: The calorific value relationship can be determined from the reduction heat law of the main action of the main reactor and calculated as →3 C: Ot: IhO. The main action of this reactor is the reduction reaction (4) of circulating element-I oxides such as H2 through the production of CO, which will be described in detail below.

On Qa is tentatively referred to as metamorphic heat; the unreduced oxides in this furnace are circulated in CO and slag (alkali and earth metals). Therefore, the input material is metamorphosed into mar reduced products and circulating oxides by the phenomenon A, and flows into Ro and warm Br (excluding the cop of the input material from the On number). From (4), the second term of the law of reduction heat is derived. It will be destroyed.

First Law 1” mat The heat of reduction MO of oxide due to C is.

It is equal to the difference between the heat of oxidation θQ and OρQa” +1 (+-MQ=ooQa −−−−−−−−(5

When calculated, the heat of H20 formation equivalent C=2,355C.

The heat of coo formation equivalent C = 2.344C, 7) Qa on the right side Qa = 3 Qtr is excessive, and (7) the reaction proceeds.

The actual situation of (7) is that the F atmosphere is 12
It is also effective to cross-stir the C blow-up streamline and the water vapor flow so as to maintain the temperature at 00°C.

(7) From (1) to 3 c: C2: Ih□, and by substituting CnHxn++ K, water gasification becomes clear as shown in (2).

In the simultaneous purification method in which Ca5, reduced metal hot water, and molten slag are extracted from Br by A phenomenon, low-melting point reduced metals, halogens, mercury, etc. are extracted at each precipitation temperature <soo' during Rθ reduction flame cooling.
