    In Europe RDF can be used in the cement kiln industry, where strict air pollution control standards of the Waste Incineration Directive apply. The main limiting factor for RDF / SRF use in cement kilns is its total chlorine (Cl) content, with mean Cl content in average commercially manufactured SRF being at 0.76 w/w on a dry basis (± 0.14% w ...

    LACW Local Authority Collected Waste (all waste collected by the local authority. This is a slightly broader concept than LACMW as it would include both this and non-municipal fractions such as construction and demolition waste) LAPC Local Air Pollution Control; LARAC Local Authority Recycling Advisory Committee; LAS Landfill Allowance Scheme

    MBT can alternatively process the waste to produce a high calorific fuel termed refuse derived fuel (RDF). RDF can be used in cement kilns or thermal combustion power plants and is generally made up from plastics and biodegradable organic waste. Systems which are configured to produce RDF include the Herhof and Ecodeco processes.

    A materials recovery facility for the recycling of domestic waste Clean materials recovery facility recycling video. A materials recovery facility, materials reclamation facility, materials recycling facility or multi re-use facility (MRF, pronounced "murf") is a specialized waste sorting and recycling system [1] that receives, separates and prepares recyclable materials for marketing to end ...

  6. Control valve - Wikipedia

    en.wikipedia.org/wiki/Control_valve

    A control valve is a valve used to control fluid flow by varying the size of the flow passage as directed by a signal from a controller. [1] This enables the direct control of flow rate and the consequential control of process quantities such as pressure , temperature , and liquid level.

    The simplest control for a wastegate is a mechanical linkage that allows the operator to directly control the wastegate valve position. This manual control is used in some turbo-charged light aircraft.

    en.wikipedia.org/wiki/Drain-waste-vent_system

    A sewer pipe is normally at neutral air pressure compared to the surrounding atmosphere.When a column of waste water flows through a pipe, it compresses air ahead of it in the system, creating a positive pressure that must be released so it does not push back on the waste stream and downstream traps, slow drainage, and induce potential clogs.

    Gate valve, mainly for on–off control, with low pressure drop; Globe valve, good for regulating flow. Uses a cylinder movement over a seat; Knife valve, similar to a gate valve, but usually more compact. Often used for slurries or powders on–off control; Needle valve for accurate flow control; Pinch valve, for slurry flow regulation and ...
