Calculating the flow rate in pipes using novel equations based on the heater method

Publikováno v: Mechanical Engineering Journal, Vol 11, Iss 2, Pp 23-00402-23-00402 (2024)

The heater method is a clamp-on type flow measurement method that can be applied to metal pipes in high-temperature environments and is useful for determining the adequate flow rate in existing pipes for the stable operation of thermal power plants.

Publikováno v: Nihon Kikai Gakkai ronbunshu, Vol 89, Iss 921, Pp 22-00261-22-00261 (2023)

Superheaters are essential components in a coal-fired power plant because they keep the highest tube wall temperature points in the radiant boiler. The pressurized steam flowing in the superheater tubes is heated via the thermal radiation and convect

Numerical simulation of the thermal radiation and convective heat transfer characteristics of the second superheater in a coal-fired thermal power plant boiler

Autor: Kizuku KUROSE, Kazushi MIYATA, Shuichi UMEZAWA, Shuichi OHMORI

Publikováno v: Mechanical Engineering Journal, Vol 9, Iss 4, Pp 22-00040-22-00040 (2022)

Superheaters are critical components in a coal-fired power plant because they sustain the highest tube wall (metal) temperature point in the boiler. The pressurized steam flowing in superheater tubes is mainly heated via the thermal radiation and con

Repair of gastro-tracheobronchial fistula after esophagectomy for esophageal cancer using intercostal muscle and latissimus dorsi muscle flaps: a case report

Autor: Kazushi Miyata, Masahide Fukaya, Masato Nagino

Publikováno v: Surgical Case Reports, Vol 6, Iss 1, Pp 1-7 (2020)

Abstract Background Gastro-tracheobronchial fistula after esophagectomy is a rare but life-threatening complication associated with high mortality. Several authors reported postoperative management of tracheobronchial fistula. However, treatment is d

Successful two-stage operation for esophageal necrosis due to proton beam therapy followed by sorafenib in a case of large hepatocellular carcinoma

Autor: Eiji Higaki, Masahide Fukaya, Kazushi Miyata, Ryosuke Kawai, Tetsuya Abe

Publikováno v: Surgical Case Reports, Vol 6, Iss 1, Pp 1-6 (2020)

Abstract Background Locally advanced hepatocellular carcinoma (HCC), which is unsuitable for standard locoregional therapies, remains a challenge to manage. Among the recently developed treatments, proton beam therapy (PBT) has been reported to achie
