This is to prevent pressure drop caused by the peak load while boiler unit usually can not respond in a short time. Example-1 is taken from one of our client, a textile mill, whose process steam flow rate fluctuates between 1.2 to 2.6 ton/h. During 16 hours operation(2 shifts), there are only 2 times staring at 6:00am and another at 1:30 pm when process need peak load of 2.6 ton/h for the span of one hour.
Habang asa 16 oras na operasyon (dalawang “shift” o termino), mayroon lamang 2 beses (ang isa ay nagaganap ng 6:00 AM at ang kasunod ay magaganap ng 1:30PM) kung saan ang proseso ay mangangailangan ng todong kargada na 2.6 tonelada/oras sa loob ng isang oras. Pagkatapos ng isang oras na may todong kargada, ang sukat ng agos ng singaw ay babalik sa normal, na nagmamarkang 1.2 – 1.5 tonelada/oras.
