Problems solved by technology

However, due to the characteristics of high carbon content and low volatile matter of petroleum coke, it may be difficult to ignite due to insufficient temperature when using conventional chain boilers for combustion. The drying section before combustion increases, resulting in the short main combustion zone behind and the fuel cannot be obtained. Complete combustion, lower thermal efficiency

Embodiment Construction

[0015] The specific implementation of the present invention will be further described below in conjunction with the accompanying drawings, but the implementation and protection scope of the present invention are not limited thereto.

[0016] Such as figure 1 As shown, the present invention includes a hopper 1, a fire grate 11, an air chamber 12, and a slag outlet 13. The fire grate 11 is driven to rotate by a driving shaft 7 and a driven shaft 14, and a front arch 9 is arranged on the upper front wall, and a rear wall There is a rear arch 10 on it, in order to promote fuel ignition and combustion; the front arch 9 is relatively high, the rear arch 10 is long and low, and the angle is relatively flat. The rear arch 10 uses heat-resistant and wear-resistant materials. The slag discharge channel 13 is located between the fire grate 11 and the rear wall. There are several air chambers 12 located below the fire grate 11. The hopper 1 is arranged outside the front wall, and the mat...

Abstract

The invention discloses a petroleum coke direct burner, comprising a hopper, a fire grate, air chambers and a deslagging channel, wherein, the fire grate is driven by a driving shaft and a driven shaft to rotate; a front arch is arranged on an upper front wall, and a rear arch is arranged on a rear wall; the deslagging channel is arranged between the fire grate and the rear wall; a plurality of the air chambers are arranged under the fire grate; the hopper is arranged outside the front wall and is internally provided with a sizing screen; the lower space of a separating baffle plate is divided into a coarse material box and a fine material box, the coarse material box is provided with a coarse material gate for controlling discharge speed, and the fine material box is provided with a finematerial gate for controlling discharge speed; and the air supply system of the air chamber is provided with an air preheater. The petroleum coke direct burner can be widely applied in the field of boiler combustion equipment, and has the advantages of simple structure, easy ignition and high combustion efficiency.

Description

technical field [0001] The invention relates to a petroleum coke direct burner. Background technique [0002] With economic development, my country's energy consumption has risen sharply. From 1978 to 2008, my country's energy consumption increased by nearly 6 times, and energy demand is increasing rapidly at an unprecedented rate far higher than GDP growth, and the huge population makes the per capita share of various conventional energy resources far below the world level . Relevant data show that my country's per capita water resources are only 2,163 cubic meters, which is a quarter of the world's average level; per capita oil reserves are also relatively low. The excessive growth of energy consumption has increased the dependence on foreign energy sources—the export volume of coal has dropped sharply, close to zero, and the dependence on foreign oil has reached more than 50%, which seriously affects my country's energy security. From the perspective of consumption stru...
