A chimney oven method

Abstract

The invention discloses a furnace drying method for a chimney. The furnace drying method comprises the steps that 1, chimney lining casting is completed, maintenance finished, and acceptance inspection is passed; 2, inspection of thermodynamic instruments and meters required for furnace drying is completed, and the temperature in the furnace drying process is monitored through a thermocouple; 3, a smoke guiding pipe is axially put in the chimney and is connected with a fan; 4, seal plates are arranged at two ends of the chimney respectively, a fire delivery hole is reserved in the seal plate at one end, a fire-leading pipe connected to a combustor extends into the chimney from the fire delivery hole, and a fan air supply port and an exhausting port are reserved in the seal plate at the other end; 5, the combustor is debugged to ensure smoke pipe smoothness; 6, furnace drying is performed, wherein a heating control program is input, the combustor is started, the flame size and fire spraying time duration are controlled through the pre-input program, and furnace drying is automatically performed according to a furnace drying curve. The furnace drying method has the advantages that the furnace drying method is suitable for various sizes of chimneys, is uniform in heating and can effectively control heating speed, heating temperature and temperature deviations.

Description

technical field [0001] The invention relates to the technical field of ovens, in particular to a chimney oven method. Background technique [0002] Some modern large-scale industrial equipment has high parameters, many parts, large volume, and heavy weight. It cannot be assembled into a whole at the manufacturing plant and transported to the device site. It can only be processed into parts at the manufacturing plant or the assembly that the transportation and unloading capacity allows can be transported to the device. On-site, combined assembly is carried out, and it is assembled into a complete industrial equipment that can be put into operation. After the industrial equipment is installed, the overall hydraulic test, air leakage test, chain test, trial run of the rotating parts, oven, boiler, chemical cleaning, pipe flushing, steam air tightness test and safety door adjustment should be carried out. [0003] Oven is an important link in the installation and construction o...

Problems solved by technology

The current chimney oven method mostly uses electric heating. Since the oven needs to be continued for a period of time, the actual operation will affect the normal operation of the oven due to the power supply. In addition, there is a hidden danger of electric leakage when using electric heating.

Another way to bake chimneys is to heat them with a furnace, but limited by the size of the furnace, this method is only suitable for smaller chimneys
