There are three points for attention in the start-up of biomass hot blast stove: First, in the process of water supply, it is necessary to check whether there are leakage phenomena in the pot drum, header orifices, valves, flanges, plugs, etc. When leakage is found, the water should be stopped and treated. When the water level of the hot blast stove rises to the negative 100mm of the drum water level gauge, the water supply is stopped. After that, the water level should remain unchanged. If the water level changes obviously, the reasons should be found out and eliminated.
Secondly, the whole process of temperature and pressure rise should be smooth and uniform, and the expansion indicators should be checked and recorded in the following stages.
Before and after Sheung Shui. When the drum pressure reaches 0.3-0.4, 10. -1.5, 2.0 and 3.9 MPA respectively, check the expansion. If abnormal expansion is found, the cause must be found out and the abnormal situation must be eliminated before the pressure can continue to rise.
Attention should be paid to the merging of three hot stoves
1. Keep the main steam pressure lower than the steam main pipe pressure 0.05-0.1 MPA in parallel furnace. If the steam pressure of hot blast furnace is higher than the main pipe pressure, it is forbidden to combine furnace.
When parallel, the steam temperature should be lower than the rated value of 30.C, maintain a lower water level, stable combustion, and pay attention to keeping the parameters of steam pressure and temperature, and slowly increase the evaporation.
3 在并列过程 中，如引起汽机的汽温急剧下降时或发生蒸汽管道水冲击时，应立即停止并炉，减弱燃烧，加强 水，待恢复正常后重新并列。
3 In the process of parallel operation, if the steam temperature of the turbine drops sharply or the water shock of the steam pipeline occurs, the furnace should be stopped immediately, the combustion should be weakened, the water should be strengthened, and the parallel operation should be restored to normal.
After parallel arrangement, the hot blast stove units shall be thoroughly inspected, and the main operation and newly discovered problems during ignition to parallel arrangement shall be recorded in the relevant record book.
5. Close the recirculation valve when the feed pump starts to supply water.
