目前,在煤粉锅炉起动操作过程中或低负荷运行时,要求使用气体燃料或重油作燃料的点火燃烧器。因为实际上,在这些过渡阶段,输送到主燃烧器中的煤的稳定、完全和可靠燃烧所必需的条件往往不是同时兼备的。因而,解决的办法依靠具有极好着火特性的助燃燃料。 Currently, ignition burners using gaseous fuel or heavy oil as a fuel are required during pulverized coal boiler start-up operation or during low-load operation. Because in practice, the conditions necessary for the stable, complete and reliable combustion of the coal delivered to the main burner during these transitional phases are often not at the same time. The solution, therefore, relies on combustion-supporting fuels with excellent ignition characteristics.
