Problems solved by technology

[0004] However, in the process of use, sometimes there will be unstable combustion and unstable pressure in the furnace or preheating combustion chamber, and once the combustion is unstable and the pressure in the furnace is unstable, it is difficult to re-adjust to a balanced state, and it is often necessary to stop the furnace and wait a few minutes. After the first purge, it is very inconvenient to add sand, feed and ignite again

Abstract

The invention relates to a novel vertical powder boiler system and a using method thereof. In order to solve the problems that an existing vertical pulverized coal boiler with a bottom burner is unstable in combustion and unstable in hearth pressure, the novel vertical powder boiler system comprises a hearth, a powder circulating combustible gas generator and the like, wherein the powder circulating combustible gas generator is arranged on one side of a vertical combustible powder boiler; a dust collecting heat exchange chamber is arranged at the bottom of the hearth; an air distribution device is arranged between the dust collecting heat exchange chamber and the hearth; a plurality of dust collecting hoppers uniformly distributed around the vertical center line of the dust collecting heatexchange chamber are arranged at the bottom of the dust collecting heat exchange chamber; each dust collecting hopper is in an inverted cone pipe shape with the large upper part and the small lower portion; the lower end of each dust collecting hopper is connected with a vertical dust discharging pipe; and each vertical dust discharging pipe is provided with a dust discharging valve. According tothe novel vertical powder boiler system and the using method thereof, operation is reliable, combustion is sufficient, and the novel vertical powder boiler system is suitable for serving as various industrial and living boilers such as power plant boilers and centralized heating boilers.

Description

technical field [0001] The invention relates to a novel vertical powder boiler system and its application method. Background technique [0002] 2018.03.23 authorized announcement, the Chinese invention patent with the announcement number CN 104791775 B discloses a vertical pulverized coal boiler with a bottom burner, 2015.08.12 authorized announcement, the announcement number is CN 204554755 U Chinese utility model disclosure waste heat boiler used in conjunction with it. [0003] The pulverized coal preheating burner disclosed in CN 104791775 B includes a preheating combustion chamber, a gas-solid separator and a feeder connected in sequence, and the three form a circulating fluidized bed gas generator. The vertical pulverized coal boiler has the advantages of sufficient combustion, small tail gas treatment burden, low cost, simplicity and convenience, and has the advantages of safe and environmentally friendly smoke discharge. [0004] However, in the process of use, som...
