Abstract

The invention brings forward a boiler heating system which comprises a first boiler, a second boiler, a transmission pipeline and a power unit. The transmission pipeline is connected to a first material-returning pipeline and a second material-returning pipeline. Circulating ash in the first boiler flows back to the first boiler through the first material-returning pipeline. Circulating ash in the second boiler flows back to the second boiler through the second material-returning pipeline. When the first boiler is in an operating state and the second boiler is in a starting state, part of the circulating ash in the first material-returning pipeline is transmitted to the second material-returning pipeline through the transmission pipeline. The power unit is connected to the transmission pipeline and is used for providing the circulating ash in the transmission pipeline with power. Through technical scheme, non-oil or low-oil ignition of the boiler can be realized, oil consumption for starting is greatly reduced and corresponding start-up cost is furthermore reduced.

Description

technical field [0001] The invention relates to the technical field of boilers, in particular to a boiler heating system. Background technique [0002] Circulating fluidized bed boiler has become one of the main technical approaches for clean coal combustion due to its low pollution and strong fuel adaptability, and it has developed rapidly in China. At present, the ignition method of circulating fluidized bed boilers mainly adopts the oil gun ignition method. During the start-up process, the primary fluidization air is heated by burning fuel oil. When the high-temperature primary fluidization air passes through the air distribution plate, the bed material is heated and started. When the temperature rises to the coal feeding temperature, the boiler feeds coal and burns, so as to achieve the purpose of starting the boiler, so a large amount of fuel oil will be consumed during the starting process. [0003] According to the actual operation situation at the site, taking the c...
