“Correct sizing of Steam Tracing systems is essential to ensure energy efficiency, adequate thermal performance and durability in industrial processes. In this article, we exploit the critical steps and variables to perform accurate calculations, ensuring that the heating solution adapts to the specific needs of each application.”
Importance of correct sizing
Steam trait is widely used in industrial processes for maintain the temperature of pipes and equipment, Preventing freezing, loss of viscosity or unwanted changes in fluids and gases. An inappropriate sizing can result in:
- Thermal efficiency loss: Superdimensioning or underdimensioning impairs temperature control.
- Energy waste: Excessive vapor consumption.
- System Failures: Poor thermal distribution or condensed accumulation.
A Tayga, with your precise technical approach, Develops personalized solutions based on strict engineering calculations to optimize performance and minimize costs.
Critical variables in the sizing calculation
Steam trace sizing involves considering specific variables to ensure that thermal energy is distributed efficiently. The main variables are:
- Maintenance temperature
- What temperature is required to keep the fluid or gas in the ideal state?
Example: Viscous oils require high temperatures to maintain fluidity.
- What temperature is required to keep the fluid or gas in the ideal state?
- Heat losses
- Determine the amount of heat that the system loses to the environment through the pipe or equipment.
Factors such as ambient temperature, line length and insulation influence this calculation.
- Determine the amount of heat that the system loses to the environment through the pipe or equipment.
- Pressão e Tipo de Vapor
- Vapor saturado or superaquecido afeta a capacidade de transferência térmica. Pressões mais altas aumentam a densidade do vapor e sua eficiência.
- Material da Tubulação
- Tubos metálicos (como aço carbono ou inox) têm condutividade térmica maior do que materiais plásticos.
- Thermal insulation
-
- A espessura e o tipo do isolamento (fibra de vidro, lã mineral, espumas) impactam na capacidade de manter o calor e minimizar perdas.
- Comprimento da Tubulação e Componentes
- O número de flanges, válvulas e suportes atua como pontos frios (heat sinks) e exige calor adicional para compensação.
- Environmental conditions
- Ambientes externos com temperaturas baixas, vento e umidade aumentam as perdas de calor e exigem cálculos mais precisos.
Etapas do Cálculo de Dimensionamento
- Calculation of heat losses
The basic equation to determine heat loss is:
Q=U×A×ΔTQ = U times A times Delta TQ=U×A×ΔT
Where:
- Q = Heat loss (W you kcal/h)
- U = Global heat transfer coefficient (W/m².K)
- A = Surface area of the piping (m²)
- ΔT = Temperature difference between fluid and environment (K)
This calculation considers the diameter, length and insulating conditions of the pipe.
- Determination of the necessary vapor capacity
The amount of vapor required to compensate for heat losses is calculated by:
m=Q(hg−hf)m = frac{Q}{(h_g – h_f)}m=(hg−hf)Q
Where:
- m = Steam flow (kg/h)
- Q = Heat loss (kcal/h)
- h_g = Saturated vapor enthalpy (kcal/kg)
- h_f = Condensed water enthalpy (kcal/kg)
This calculation determines the amount of vapor necessary to maintain the temperature.
- Cold Point Compensation
To compensate for flanges, valves or brackets that dissipate heat more intensely, Additional values apply to calculated vapor flow. Each component has a correction factor that must be added to the main calculation.
