Full title and description

VDI 2263 Blatt 7.1:2013-03 — Dust fires and dust explosions; Hazards — assessment — protective measures; Fire and explosion protection in spraying and drying integrated equipment — Examples. The guideline provides practical examples and recommendations for risk assessment and protective measures specifically for spray-drying and integrated spraying/drying equipment where combustible dust/air, vapour/air or hybrid mixtures may be present or form during normal operation.

Abstract

This guideline gives manufacturers and operators practical advice and example-based solutions for protecting spray-drying and related integrated equipment against dust fires and dust explosions. It explains state-of-the-art protective measures, approaches to a coherent risk assessment and specific implementation examples (including venting combined with isolation, suppression combined with isolation, and re-zoning by inerting). The document is intended to be used in conjunction with VDI 2263 Blatt 7.

Scope

Applies to explosion protection measures for spray-drying and integrated spraying/drying installations in which combustible dust/air mixtures, vapour/air mixtures or hybrid mixtures can occur during intended use. The guideline presents worked examples to support risk assessments and the selection and implementation of protective measures; it assumes familiarity with the main VDI 2263 Part 7 guidance. Annexes provide illustrative examples of venting with isolation, suppression with isolation and inerting/re-zoning strategies.

Key topics and requirements

• Identification of dust fire and dust explosion hazards specific to spray-drying and integrated equipment.
• Coherent, example-based risk assessment methodology tailored to spray dryers.
• Selection and implementation of protective measures: prevention, ventilation/venting, isolation, suppression, inerting and combinations thereof.
• Design and application examples showing how protective measures can be combined (e.g., venting + isolation; suppression + isolation; re-zoning by inerting).
• References to normative terms, symbols and definitions relevant to explosion protection in this application area.

Typical use and users

Used by process engineers, safety/EHS managers, equipment manufacturers, plant designers, explosion protection specialists and competent authorities involved in the design, operation, inspection and certification of spray-drying and related processing equipment. The guideline is valuable during design, risk assessment, commissioning and when selecting protective measures and mitigation strategies.
