Moisture Matters: How Fuel Humidity Drives Combustion Instability, NOx Slip, and Corrosive Chemistry in Condensing Biomass Heat Plants (Part 2 of 2)
0 Comments on Moisture Matters: How Fuel Humidity Drives Combustion Instability, NOx Slip, and Corrosive Chemistry in Condensing Biomass Heat Plants (Part 2 of 2)
Introduction In modern biomass heat plants, most discussions about NOₓ reduction focus on technologies like SNCR or SCR. Yet in practice, many of the emission and corrosion problems observed in condensing heat plants do not originate in the reduction system itself, but much earlier — in the combustion chamber.At the…
NOx Emission Control in Biomass Heating and CHP Plants – Challenges of Process Stability and Fuel Quality (Part 1 of 2)
0 Comments on NOx Emission Control in Biomass Heating and CHP Plants – Challenges of Process Stability and Fuel Quality (Part 1 of 2)
Introduction Controlling nitrogen oxides (NOx) emissions in biomass heating and combined heat and power (CHP) plants remains one of the most complex operational challenges in modern renewable energy systems. Based on WEProS’s experience, even well-designed installations – equipped with selective non-catalytic reduction (SNCR) systems – face significant difficulties in achieving…
Turning Loss into Opportunity: How Waste Heat Recovery Can Offset the Energy Penalty of CO₂ Capture
0 Comments on Turning Loss into Opportunity: How Waste Heat Recovery Can Offset the Energy Penalty of CO₂ Capture
From Problem to Opportunity As discussed in the previous article, carbon capture systems—though essential for decarbonization—lead to a reduction of a plant’s net power output. This occurs because part of the steam extracted from the turbine is redirected to provide thermal energy for solvent regeneration in the CO₂ capture unit….
🧩 The Cost We Don’t See: How Carbon Capture Drains Energy from the Grid
0 Comments on 🧩 The Cost We Don’t See: How Carbon Capture Drains Energy from the Grid
Abstract Carbon capture is often praised as a key step toward decarbonization — but few talk about its hidden side effect: the massive energy it consumes.Every tonne of CO₂ captured means less power for the grid, forcing plants to burn more fuel just to stay even.This article unpacks that paradox…
Understanding Sampling Uncertainty in Mass Balance and Recovery Calculations in Municipal Waste Sorting Plants
0 Comments on Understanding Sampling Uncertainty in Mass Balance and Recovery Calculations in Municipal Waste Sorting Plants
Why this topic matters When evaluating the performance of a municipal waste sorting plant, the key metric is the recovery rate — how much of a specific material (e.g., drink cartons, plastics, metals) is successfully separated into product fractions.However, recovery is not directly measured. It is calculated from the mass…
🔍 How “recovery” is actually calculated in a sorting plant
How recovery is really calculated in sorting plants and why mass balance accuracy is key to understanding recycling efficiency.
