Abstract
[problema] aprimorar a fluxibilidade de uma camada de depósito de material de gesso em uma fornalha para, desta forma, evitar o desenvolvimento de "desigualdade" no gesso calcinado, enquanto também reduz o consumo de combustível em uma fornalha de calcinação. [solução] um dispositivo de calcinação de gesso é provido com: uma fornalha de calcinação de gesso (1, 3-7) tendo uma superfície de parede interna de fornalha, que é circular ou anular no plano; e um tubo de combustão (2) disposto no centro de um corpo de fornalha, em que o material de gesso (m) na fornalha é calcinado ou secado por um fluxo de jato de gás em alta temperatura (hg) ejetado a partir de uma parte inferior do tubo de combustão. a fornalha de calcinação inclui um dispositivo auxiliar do tipo lâmina fixa ou lâmina móvel para impelir o material de gesso na vizinhança da superfície de parede interna da fornalha em uma direção circunferencial da fornalha de calcinação, ou auxiliando o movimento na direção circunferencial do material de gesso na vizinhança da superfície de parede interna da fornalha. o dispositivo auxiliar inclui uma pluralidade de lâminas fixas (10) arranjadas em intervalos angulares na direção circunferencial em uma área periférica externa de extremidade inferior do tubo de combustão, ou um agitador (30) que penetra através de uma superfície cônica ou uma superfície periférica interna constituída pela superfície de parede interna da fornalha.
