MCR = Maximum Continuous Rating. Green range (75% to 95%) indicates the optimum selection point with best efficiency; far below this range, fixed losses weigh more on operation; far above it, stack losses and combustion effort tend to increase. Operating near this point provides a better balance among efficiency, steam generation, and process stability.

O resultado apresentado por esta ferramenta é uma seleção rápida e preliminar, baseada principalmente na capacidade requerida informada.

A escolha definitiva da caldeira, porém, deve considerar outros critérios relevantes de processo, como pressão de trabalho, temperatura, combustível, perfil de consumo, variações de carga e regime operacional da planta.

Isso significa que a mesma demanda de vapor pode levar a configurações diferentes, dependendo da aplicação e da forma como o processo consome energia térmica ao longo do tempo.

Use este resultado como ponto de partida. Para a definição técnica final, recomenda-se uma análise mais completa da aplicação e das condições reais de operação.

Por que usamos 95 °C como referência de capacidade nominal? Porque essa condição representa melhor a operação industrial real. A produção de vapor varia conforme a temperatura da água de alimentação, e referências baseadas em água fria, como 20 °C, podem superestimar a capacidade aparente do equipamento e distorcer a leitura de eficiência. Ao adotar 95 °C, a Steammaster utiliza uma base mais realista e consistente para seleção e comparação entre modelos.

Combustion system: RECIPROGRELHA

  • Multi-zone drying / devolatilization / burnout with controlled air injection
  • Reversible grate elements (180°) to practically double service life
  • Water-cooled side seals and robust drive for severe operation

Heat recovery: air preheater + economizer

  • Air preheater recovers exhaust heat to stabilize combustion and reduce fuel demand
  • Economizer preheats feedwater to increase efficiency and reduce fuel consumption

Fuel feeding and safety

  • Hydraulic feeder with synchronized double gates for airtight sealing and backfire protection
  • Buffer capacity sized for continuous operation (scope dependent)
