Abstract

The invention discloses a methyl alcohol based boiler ignition system. The system comprises a methyl alcohol coarse filter, wherein an inlet of the methyl alcohol coarse filter is connected with a methyl alcohol raw material main pipe, and an outlet is connected with a methyl alcohol liquid storage tank, a methyl alcohol fine filter, a methyl alcohol pump and an atomization nozzle. A steam inlet is further arranged at the atomization nozzle and is connected with a steam main pipe. By means of the system, initial investments and operating costs are reduced, the operating responding speed is improved, combustion products are pollution-free to the atmosphere, and the energy-saving and environment-friendly purpose is achieved.

Description

[0001] technical field [0002] The invention belongs to the technical field of boiler equipment, and in particular relates to a methanol-based boiler ignition system. Background technique [0003] At present, the ignition and stable combustion of large boilers are traditionally achieved by burning fuel oil. In recent years, with the global energy shortage, the price of fuel oil continues to rise, and the fuel oil for thermal power generation is increasingly restricted. Therefore, the oil used for boiler ignition and stable combustion is evaluated as an important indicator. In order to reduce the consumption of fuel oil, the traditional method is to increase the fineness of coal powder, increase the preheating temperature of air-powder mixture and secondary air, The use of pre-combustion chamber burners, the selection of small atomizing nozzles for ignition, etc. However, if the fuel oil is to be further reduced to the point where no oil is used, a new process that is comple...
