[0008]
Coal is a solid fuel, and natural gas is a gaseous fuel. Due to the different fuel characteristics of the two fuels, the structure of the burner is quite different. The current burner technology is still unable to adapt to the combustion of coal and natural gas at the same time.

The invention belongs to the technical field of boilers, and particularly relates to a fire coal and natural gas dual-purpose boiler system and a using method thereof. According to the technical scheme, the fire coal and natural gas dual-purpose boiler system comprises a boiler body, the bottom of the boiler body is connected with a slag remover, the upper portion of the boiler body is connected with a tail flue, and a plurality of natural gas combustors and pulverized coal combustors are arranged on the boiler body; the system further comprises a natural gas pipeline communicated with the natural gas combustors and a pulverized coal pipeline communicated with the pulverized coal combustors, and the pulverized coal pipeline is connected with a coal mill. The primary air duct is connected with the coal mill, the secondary air duct is communicated with the natural gas burners and the pulverized coal burners, and a bypass air duct is connected between the primary air duct and the secondary air duct. The invention provides a fire coal and natural gas dual-purpose boiler system capable of independently using coal or natural gas as fuel and a using method thereof.
Description
technical field [0001] The invention belongs to the technical field of boilers, and particularly relates to a coal-fired and natural gas dual-purpose boiler system and a use method thereof. Background technique [0002] my country's current energy structure is still dominated by coal, so that the power plant boilers and industrial steam boiler systems in the market are basically designed with coal as a single fuel. However, when the coal supply is insufficient or is greatly affected by coal price fluctuations, the boiler system cannot operate normally, affecting the power supply of the unit or the steam demand downstream of the industrial park. On the other hand, under the national energy policy of green, low-carbon, energy saving and environmental protection, coal will not always become the mainstream fuel for boiler systems. Compared with coal, natural gas contains almost no harmful substances such as sulfur and dust. The content of pollutants produced by combustion is lo...
