Problems solved by technology

[0004] It can be seen from the above that the coal-water slurry boiler in the prior art can only use coal-water slurry as a single fuel, and heat the liquid in the boiler by burning the coal-water slurry
Therefore, the scope of use of boilers in the prior art is relatively narrow

Embodiment Construction

[0016] Specifically, the combustion room 2 in hybrid boilers in this embodiment of mixed -powered boiler 2 includes the pre -combustion chamber 21 and the full room 22 in the mixed power boiler.The mixed power boilers of dried powder can use two different fuels: coal slurry and dried coal slurry dried powder. The length value of the pre-combustion chamber 21 in the embodiment to the length of the full room 22 is 0.4-0.9.Specifically, due to the difficulty of dried coal slurry and water coal slurry, it is difficult to get the same on fire.The burning room with water and cold water 22, which is conducive to the burning of water and coal slurry. At the same time, if the pre -combustion room 21 is relatively long, it is easy to cause the temperature in the pre -combustion room 21 is too high.By setting the length value of the pre-combustion chamber 21 and the full-burn room 22 to 0.4-0.9, a hybrid boiler for mixed power boilers of water coal and coal plasma dried flour can be ensured ...

Abstract

The invention provides a coal water slurry and coal water slurry powder combusting hybrid boiler which comprises a combustor, a combustion chamber and a boiler body, wherein the combustor is fixedly arranged outside the combustion chamber and comprises a precombustion chamber and and after-combustion chamber which are communicated with each other, the precombustion chamber is adjacent to the combustor, and the length ratio of the precombustion chamber to the after-combustion chamber is 0.4-0.9. The coal water slurry and coal water slurry powder combusting hybrid boiler also comprises a first longitudinal jet blast pipe and a second longitudinal jet blast pipe, wherein the first longitudinal jet blast pipe and the second longitudinal jet blast pipe are fixedly arranged in after-combustion chamber respectively in a direction perpendicular to the spraying direction of the combustor, a plurality of first air ports are arranged on the first longitudinal jet blast pipe, and the first air ports face toward the combustor; a plurality of second air ports are arranged on the second longitudinal jet blast pipe, and the air outlet direction of the second air ports is upward. Thus, the usable range of the coal water slurry and coal water slurry powder combusting hybrid boiler is increased.

Description

Technical field [0001] The invention involves boiler equipment, especially a hybrid boiler with water -burning coal slurry and water coal slurry. Background technique [0002] At present, the working principle of the boiler is usually burned indoors in the burning room of the boiler through fuel. The liquid accommodated in the boiler is heated and the steam, hot water or other bed thermal media are provided according to different needs.Widely used for various boilers. [0003] The existing technology usually includes components such as a burner, combustion chamber, and boiler body. It is sprayed into the burning room of the boiler to burn by spraying the coal plasma into the burning room of the boiler to heat the liquid in the heating surface of the boiler. [0004] It can be seen from the above that the existing technology can only use a single coal plasma as a fuel in the existing technology, and heated the liquid in the boiler by burn the coal plasma.Therefore, the use of boil...
