Chemical | Yokogawa Philippines

Chemical plants typically rely on continuous and batch production processes, each posing different requirements for a control system. A continuous process calls for a robust and stable control system that will not fail and cause the shutdown of a production line, whereas the emphasis with a batch process is on having a control system that allows great flexibility in making adjustments to

Used to control the depth of coal entering the boiler furnace on chain grate stokers. Coal Ram: Distributes coal evenly into the center retort on underfeed stokers and forces the coal up to the top where it is burned. Coal Scale: Measures and records the amount of coal fed to stoker-fired or pulverized coal-fired boilers. Code: A regulation or law.
