Description

MAXSTI气动控制箱
深圳恒泰讯MAXSTI执行器就地控制柜,风箱挡板控制装置。它是火力发电厂配套锅炉安全经济燃烧所必须的一个重要环节。根据燃料种类(气体、油、煤)的不同和燃烧器投放只数的不同,该装置接受DCS电信号,将其转换为气信号送给现场执行器来控制风门的开度或摆动火嘴的上下摆动角度,达到经济燃烧的目的。它是控制室到现场气动执行器之间的一个中间信号转换装置。
本装置既适用于四角燃烧锅炉,也适用于前后墙布置燃烧器的锅炉。由于燃烧方式和燃烧器组合方式多变,风箱挡板控制装置组态也不尽相同。目前本装置能通过远方控制方式对风箱挡板实现单只对角或一层控制,并根据锅炉各种运行工矿,配置不同控制方式。

Shenzhen Hengtai News MAXSTI actuator local control cabinet, bellows baffle control device. It is an important part of the safe and economical combustion of boilers in thermal power plants. Depending on the type of fuel (gas, oil, coal) and the number of burners, the device accepts the DCS electrical signal and converts it to a gas signal to the field actuator to control the opening of the damper or to oscillate the burner. The angle of up and down swings to achieve the purpose of economic combustion. It is an intermediate signal conversion device between the control room and the on-site pneumatic actuator.
The device is suitable for both four-corner combustion boilers and boilers with burners arranged on the front and rear walls. Due to the variety of combustion modes and burner combinations, the configuration of the bellows baffle controls is not the same. At present, the device can realize single diagonal or one-layer control of the bellows baffle by remote control, and configure different control modes according to various operating industries of the boiler.
