Abstract
The utility model provides a high-efficiency coal-burning boiler, comprising a burning chamber; the burning chamber is equipped with a water/steam-spraying apparatus which is composed of a steel pipe and a steel nozzle screwed with each other; the steel pipe goes through the bottom or side of the burning chamber; when coal is burning in the burning chamber, water or steam is sprayed on the coal in the burning chamber through the water/steam-spraying apparatus so as to gasify the coal and generate carbon monoxide and hydrogen which can burn fully with oxygen to improve the coal burning efficiency; the full burning of coal granule can also reduce the dust content in flue gas and protect environment. The utility model is suitable for civilian and industrial coal-burning boiler.
Description
Technical field
The utility model relates to a kind of boiler, especially relates to a kind of coal-burning boiler.
Background technology
At present, China's industry or civil boiler major part are obtained heat energy by direct burning coal, in combustion process, a large amount of unburnt carbon granules, dust and flue gas are discharged in the air simultaneously, the one, coal does not make full use of, waste resource, the 2nd, contaminated environment; Also having a kind of is with the coal gasification after-combustion, though this can overcome the above problems, needing increases vaporizer, and structure is numerous and diverse, and the processing cost height is not easy to promote.
The utility model content
The purpose of this utility model overcomes above the deficiencies in the prior art exactly, provide a kind of simple in structure, production cost is low, the convenient boiler that uses and can improve the coal efficiency of combustion.
The technical solution of the utility model is:
A kind of efficient fuel coal boiler comprises the combustion chamber, is characterized in that in inside, combustion chamber water spray (or steam) being set installs.
Described water spray (or steam) device is made up of steel pipe and iron and steel shower nozzle, and is connected by screw thread, and the steel pipe of this water spray (or steam) device is upward through from the bottom vertical of combustion chamber, and shower nozzle is positioned at the top of coal-fired layer; Described shower nozzle is cylindric, the cylinder end sealing, and the side is evenly distributed with circular hole.
Described water spray (or steam) device is made up of steel pipe and iron and steel shower nozzle, and is connected by screw thread, and the steel pipe of this water spray (or steam) device passes from the top, side of combustion chamber, and shower nozzle is facing to the coal-fired layer of bottom; Described shower nozzle is a round pie, and the surface is evenly distributed with circular hole.
Described water spray (or steam) device is a steel pipe, and directly the bottom from the combustion chamber is upward through, and a jet end is positioned at the below, coal seam.
Beneficial effect: a kind of efficient fuel coal boiler of the utility model, at indoor water spray (or steam) device that is provided with of boiler combustion, coal is when the boiler combustion Indoor Combustion, by coal water spray or the water vapour of water spray (or steam) device in the combustion chamber that is provided with, make coal gasification, generation carbon monoxide and hydrogen fully burn with oxygen then, thereby have fully improved the efficiency of combustion of coal.Simultaneously,, also reduced the content of dust in the flue gas, protected environment because the coal particle fully burns.
Description of drawings
Fig. 1 is the chamber structure schematic diagram of the utility model embodiment 1;
Fig. 2 is the chamber structure schematic diagram of the utility model embodiment 2.
The specific embodiment
The utility model is described in further detail below in conjunction with accompanying drawing;
Embodiment 1: a kind of efficient fuel coal boiler of the utility model, and as shown in Figure 1: comprise combustion chamber 1,1 inside is provided with water spray (or steam) device in the combustion chamber, and this water spray (or steam) device is made up of steel pipe 2 and iron and steel shower nozzle 3, and is connected by screw thread; The steel pipe 2 of water spray (or steam) device from the combustion chamber 1 bottom centre pass vertically upward, shower nozzle 3 is positioned at the top of coal-fired layer; Described shower nozzle 3 is cylindric, the cylinder end sealing, and the side is evenly distributed with circular hole 4.Coal is when boiler furnace 1 internal combustion, and the coal water spray of water spray (or steam) device in the combustion chamber by being provided with makes coal gasification, and generation carbon monoxide and hydrogen fully burn with oxygen then, thereby fully improve the efficiency of combustion of coal.
Embodiment 2: a kind of efficient fuel coal boiler of the utility model, and as shown in Figure 2: comprise combustion chamber 1,1 inside is provided with water spray (or steam) device in the combustion chamber, and this water spray (or steam) device is made up of steel pipe 2 and iron and steel shower nozzle 3, and is connected by screw thread; The steel pipe 2 of water spray (or steam) device passes from the top, side of combustion chamber, and shower nozzle 3 is facing to the coal-fired layer of bottom; Shower nozzle 3 is a round pie, and the surface is evenly distributed with circular hole 4.
Embodiment 3: a kind of efficient fuel coal boiler of the utility model, comprise combustion chamber 1, and the water spray steam unit is a steel pipe 2, and directly 1 bottom is upward through from the combustion chamber, and a jet end is positioned at the below, coal seam.When water vapour rises, contact with the coal seam of burning, make coal gasification, generation carbon monoxide and hydrogen fully burn with oxygen then, thereby fully improve the efficiency of combustion of coal.
Be understandable that: to those of ordinary skill in the art; can make other various corresponding changes and distortion according to the technical solution of the utility model and design; as change the position of shower nozzle, the quantity of increase shower nozzle etc., and all these changes and distortion all should belong to protection domain of the present utility model.
