Small Furnace Experiments for Wood Burning Pyrolysis Models

Popis výsledku v původním jazyce

This article presents a study focused on the fire resistance of steel structures when solid wood cladding or OSB panels are used. The measured properties of wood at elevated temperatures are presented. Wood pyrolysis is studied with the use of available procedures for calculating the influence of pyrolysis on fire development. The development of the charred layer is studied as a desirable part that fills the insulating layer. When this effect is shown in the experiments, the charred layer slows down the heat transfer to the structure. The charred layer will last on the steel member throughout the investigation or will fall off and expose the steel member to more rapid heating. The paper presents insights identified in previous research. Our study proposes advanced procedures for predicting the charring layer. By calibrating the thermal characteristics of the wood, a method is established to address the analysis of a charred wood layer exposed to fire. The study presents the influence of input data on the accuracy of the charred layer calculation, the development of pyrolysis, i.e., the fire protection effect on the structure or on the progress of the fire.
