Achieving Price Stability for Precious Metal Catalytic Converters Precious metals such as platinum and palladium are integral components in the majority of catalytic converters used in wood stoves and commercial ovens. These metals, while effective in their catalytic roles, come with a hefty price tag. Platinum currently commands approximately Euro 26 per gram, with palladium surpassing that at about Euro 36 per gram. This article explores the challenges posed by the fluctuating prices of these precious metals and offers practical solutions for manufacturers in the cooking and heating appliance industry. The Price Predicament For manufacturers of wood stoves and ovens, the volatility of precious metal prices presents a significant hurdle. Rapid fluctuations in costs make it difficult to control production expenses. This uncertainty can directly impact the pricing and profitability of their products. Stockpiling Solutions One obvious solution to mitigate price volatility is to stockpile catalytic converters that incorporate precious metals. However, this strategy [...]
UK Woodstove Regulations Post-Brexit: A Path Diverging from the EU? The aftermath of the Brexit referendum led to a series of significant decisions regarding the UK's relationship with the European Union. Among these was the potential divergence of British product standards from EU product standards, resulting in the development of a UK-specific certification mark, the UKCA mark, to replace the familiar CE mark. While this shift raised concerns about increased costs for businesses, recent developments suggest varying implications for different sectors, including woodstove and flue pipe manufacturers. A Complex Transition The Brexit referendum primarily focused on the UK's EU membership and did not explicitly address its single market status. Nevertheless, then-Prime Minister Theresa May's subsequent decision to depart from the single market set the stage for potential divergence in product standards. The CE mark, which previously signified compliance with EU regulations, was to be replaced by the UKCA mark, indicating conformity with UK product [...]
Demystifying Condensable Particulate Matter: What You Need to Know In everyday scenarios, we often encounter situations where exhaust emissions raise questions about the performance of pollution control devices, such as diesel particulate filters. This article delves into the concept of condensable particulate matter and its significance in understanding emissions from various sources, including vehicles, stoves, and industrial processes. Defining Condensable Particulate Matter Condensable particulate matter refers to substances that exist in gaseous form when exposed to high temperatures, as in the exhaust pipes of vehicles, chimneys, or ovens. However, when these gases cool down to ambient temperatures, they undergo a phase change, condensing into liquid or solid particles. Notable examples include diesel fuel, fats and oils present in food, and wood tars like creosote. Crucially, condensable particulate matter cannot be captured using filters at the process temperature because it initially exists in gaseous form, which readily passes through filters. In contrast, "filterable particulate matter" [...]
Should Woodstoves Be Banned in Cities? A Deeper Look The debate over whether domestic wood burning, often associated with health concerns, should lead to the banning of woodstoves in urban areas is a complex issue. In this article, we present several reasons why a complete ban may not be the best approach, emphasising the need for a more balanced strategy to address air pollution. Accessibility and Usage: In urban settings, only a minority of residents rely on wood-burning stoves. Many live in apartments without chimneys, making woodstove installation impractical. Moreover, gas and electricity are readily available energy sources, while securing firewood can be challenging in cities. Consequently, wood burning is not a mainstream heating option in urban areas. Simplistic Solutions: Outright bans on woodstoves in cities oversimplify the complex issue of air pollution. Such bans may hinder technological advancements and discourage innovation in cleaner wood-burning technologies. Rural Considerations: Woodsmoke-related problems are often more severe [...]
Burning wood sounds simple, but it’s actually a surprisingly complicated process involving six discrete stages, during which the solid wood is gradually converted into flammable gases, which are then oxidised to produce heat.
