Embodiment Construction

[0043] like Figure 1 to Figure 3 Shown, be the method for a kind of coal combustion efficient desulfurization, denitrification of the present invention, comprise the steps:

[0044] 1) Coal feeding control

[0045] a. Put the burning coal on the coal feeder, adjust the speed of the coal feeder to adjust the amount of coal fed to the coal feeder;

[0046] b. Lead the supplied coal into the heating tank to raise the temperature of the burning coal. The temperature in the heating tank rises to 820-935 °C, and air is introduced into the heating tank, and the excess air coefficient is 0.8-1.2;

[0047] 2) Industrial dust removal

[0048] a. CO in raw material pipe 1 2 The mixed gas is passed into the dust removal tower 2, and the preliminary dust removal is carried out through the dust baffle 3, and the dust enters the dust collection tank 4 after being blocked by the ash baffle 3 under the action of gravity;

[0049] b.CO 2The mixed gas passes through the primary dedusting c...

Abstract

The invention discloses a method for efficient desulfuration and denitration in coal combustion. The method comprises the steps: (1) coal feeding control; (2) industrial dust removal; (3) smoke denitration; (4) drying dehydration; (5) smoke desulfuration; and (6) smoke heat exchange. The problems that as for an existing circuit board, after printing punching, hole positions cannot be accurately detected, and after the hole positions are not accurate, later manufacturing is influenced are solved.

Description

technical field [0001] The invention relates to the technical field of coal combustion and ultra-low emission, and specifically relates to a method for efficient desulfurization and denitrification of coal combustion. Background technique [0002] Circulating fluidized bed (CFB) combustion technology is a new type of clean combustion and emission technology developed in recent years, which has been widely used and vigorously developed at home and abroad. On the one hand, the circulating fluidized bed boiler has a wide range of fuel adaptability, and can be used for general steam coal, as well as washed coal gangue, washed medium coal and coal slime, etc.; on the other hand, the circulating fluidized bed boiler has high combustion efficiency, and the furnace High-efficiency desulfurization, and low emission of nitrogen oxides and other environmental protection features. At the same time, the circulating fluidized bed boiler also has the advantages of large load adjustment ra...
