Embodiment Construction

[0008] Well known; do not use mixed gas (H 2 O, O 2 ) combustion, the reaction of fixed carbon combustion is

[0009]

[0010]

[0011]

[0012] The invention is designed according to the principle of thermodynamic balance of coal combustion. Use a small amount of steam and air to convert it into a mixed gas with a certain temperature (H 2 O, O 2 ) is injected into the furnace, a negative pressure area is formed at the injection port, and the CO and C particles in the heat-absorbing area (130-400°C) and the flue gas (CO in the heat-generating area (600-700°C) 2 , CO, etc.) supplement this area to form a vortex flow, prolong the residence time in the main combustion area, and promote the C particles in the heat-absorbing area and the CO in the exothermic area to be further heated. At this time, the hot carbon captures oxygen, and then generates Activated Hydrogen (H)

[0013]

[0014] When the mixed gas is continuously injected into the furnace,...

Abstract

The invention relates to a coal boiler burning-auxiliary dust cleaner which can fully burn the coal and solve the black smoke problem of chimney with energy-saving effect and reducing the soot Ringlemann less than 1 level. It comprises an ejection cylinder, an ejector, wind adjusting gate, a steam three-through, a case, a steam adjusting rod and a steam pipe connected to the steam division cylinder via pipeline. It is characterized in that: the steam three-through is mounted inside the case; the ejection cylinder is mounted at the front end of case; the wall of case has cooling wind hole; one end of steam three-through is connected to the steam pipe while another end is connected to the ejection cylinder; the back end face of ejection cylinder is the flange, which has a wind inlet, and its center has a ejector; and the ejector has a nozzle. The invention can apply variable coal boilers with environment-friendly and energy-saving effects.

Description

Technical field: [0001] The invention relates to the technical field of boiler dedusting, in particular to a coal-fired boiler combustion-supporting deduster for eliminating black smoke from a coal-fired steam boiler. Background technique: [0002] The black smoke and dust produced during the combustion of coal-fired boilers are one of the main factors causing environmental pollution. The main reason is that the tiny particles produced when the coal in the furnace is not completely burned are sucked away by the airflow and discharged from the chimney. of. In recent years, it is not uncommon for boilers to be banned by environmental protection departments because they fail to meet emission standards. In order to solve the problem of environmental pollution caused by coal-fired boiler emissions, oil-fired and gas-fired boilers have come out one after another, but due to the high fuel costs of oil-fired and gas-fired boilers, they are difficult to be accepted by users; therefo...
