The present disclosure relates to a milk-of-lime preparation apparatus and preparation method having waste heat recovery line, that may recover waste heat generated during preparation of liquid milk-of-lime and deliver the recovered waste heat to water, so as to supply the water at an optimal temperature necessary for a hydration reaction, thereby increasing the reaction efficiency and reducing the preparation time of the milk-of-lime. Especially, the milk-of-lime preparation apparatus consists of a water tank that receives room temperature water from a water supply pipe and stores the received water inside the water tank; a raw material input pipe that transfers calcine lime powder from one end to the other end through pressure supply from a BCT vehicle that carries the calcine lime powder; a water input pipe of which one end is connected with the water tank, and that receives the water stored inside the water tank and transfers the received water to the other end; a milk-of-lime tank that receives the water from the other end of the water input pipe, that receives the calcine lime powder from the other end of the raw material input pipe, and that stirs the received calcine lime powder and the water by means of a stirrer installed inside the milk-of-lime tank, to prepare and store milk-of-lime; a discharge pipe that is installed at one side of the milk-of-lime tank to discharge the milk-of-lime stored inside the milk-of-lime tank; and a waste heat recovery line that circulates the water such that the water stored inside the water tank exchanges heat with the milk-of-lime stored inside the milk-of-lime tank and then is stored back inside the water tank.

A system includes a source, a detector, and a controller. The source is configured to emit electromagnetic energy toward two plies of film. A portion of the emitted electromagnetic energy is within a range of wavelengths. The detector is arranged to detect electromagnetic energy propagating away from the two plies of film. The detector detects electromagnetic energy within the range of wavelengths and generates signals indicative of intensity of detected electromagnetic energy. The controller controls operation of the foam-in-bag system based the signals from the detector. The film is transmissive of electromagnetic energy in the range of wavelengths. When dispensed between the two plies of film, one or both of foaming chemical precursors or foam formed from a reaction thereof is opaque to electromagnetic energy in the range of wavelengths.

A system includes a dispenser, first and second feed lines, and heating zones. The dispenser dispenses a first chemical precursor and a second chemical precursor. The first feed line permits flow of the first chemical precursor from a first source to the dispenser. The second feed line permits flow of the second chemical precursor from a second source to the dispenser. The heating zones are located along the first and second feed lines. The heating zones include a first heating zone located around a first portion of the first feed line and a second heating zone located around a first portion of the second feed line. The first heating zone and the second heating zone are independently controllable to independently control temperature around the first portion of the first feed line and temperature around the first portion of the second feed line.
