摘要： PROBLEM TO BE SOLVED: To stabilize the pulverizing part of a roller mill to make self-exciting vibration hardly occur even if secular distortion thereof is encountered.
SOLUTION: In the roller mill for pulverizing raw material 1 by linking a pulverizing race 5 of a turntable 3 and pulverizing rollers 18 together, both the outer side parts at the pulverizing surface in the crossing direction of the pulverizing roller 18 are formed of hardened overlay parts 19, and the central part at the pulverizing surface of the pulverizing roller 18 is formed of parent material to make it a parent material pulverizing surface. Since the hardness (wear resistance) of material at the pulverizing surface of the pulverizing roller 18 is thus differentiated in the crossing direction, the pulverizing surface of the pulverizing roller 18 is worn and deformed so that its central part becomes hollow with time and the rolling of the pulverizing roller 18 is kept stationary, thus self-exciting vibration hardly occurs, moreover, since the recess in the central part of the pulverizing roller 18 progresses at the use period of the mill is lengthened, the longer it is used, the more hardly the self-exciting vibration occurs.

摘要翻译：要解决的问题：为了使辊磨机的粉碎部稳定，即使遇到其长期变形也难以发生自激振动。解决方案：在用于粉碎原料1的辊磨机中，通过将转盘3的粉碎座圈5和粉碎辊18连接在一起，粉碎辊18的交叉方向上的粉碎表面的外侧部分由硬化覆盖层部件19，粉碎辊18的粉碎面的中央部由母材形成，使其成为母材粉碎面。由于粉碎辊18的粉碎面的材料的硬度（耐磨耗性）因此在交叉方向上有差异，所以粉碎辊18的粉碎面磨损变形，使其中心部分随时间变得中空，粉碎辊18保持静止，因此几乎不发生自激振动，此外，由于粉碎辊18的中心部分中的凹部在轧机的使用期间进行延长，所用时间越长，几乎不发生自激振动。

摘要： PROBLEM TO BE SOLVED: To prevent slagging from occurring by providing a swirling device for swirling and injecting secondary air for combustion around a fuel injection nozzle and a plurality of tertiary air nozzles for injecting tertiary air from around the swirling device into an interior of a furnace without swirling the tertiary air. SOLUTION: A nozzle 41 for pulverized coal having a flame stabilizer 43 provided at an end portion is provided with a start-up oil burner 42 inserted in a center thereof and secondary and tertiary air is fed as combustion air. The combustion air is regulated at a specified flow rate by means of a flow regulating damper 44 before being fed as secondary air 45 and tertiary air 46. The secondary air 45 is swirled around the nozzle 41 for pulverized coal by a swirling vane 47 and is fed into an interior of a furnace. Secondary air resistor 48 is provided as a swirling device besides the swirling vane 47 in order to intensify swirling of the secondary air. The tertiary air 46 is injected from a tertiary air nozzle in a direction of injection fumed about a burner throat. Slag can be removed without influence of burner capacity by employing the tertiary air injecting method as described above.
