Steam Calculators: Boiler Calculator

Mar 17, 2015 · Steam, Boiler, and Blowdown Pressure are the same. Combustion Efficiency is the % of fuel energy that is directly added to the feedwater and not otherwise lost or used. Blowdown Rate is the % of incoming feedwater mass flow rate that leaves the boiler as a saturated liquid at boiler pressure.

Boiler Efficiency - an overview | ScienceDirect Topics

The biggest heat loss from a steam generator is the heat lost with the exiting flue gas. The flue gas loss depends on the final flue gas temperature and the amount of flue gases. related to the change in the boiler efficiency, the following equation can be used: Install turbulators in the fire-tubes to create more turbulence and thus

Boiler (power generation) - Wikipedia

A boiler or steam generator is a device used to create steam by applying heat energy to water.Although the definitions are somewhat flexible, it can be said that older steam generators were commonly termed boilers and worked at low to medium pressure (7–2,000 kPa or 1–290 psi) but, at pressures above this, it is more usual to speak of a steam generator.

a. Adjust unit to fire at rated capacity. Record fuel manifold pressure. b. Adjust draft and/or fuel pressure to obtain acceptable, clean combustion at both high, medium and low fire. Carbon monoxide value should always be below 400 ppm at 3% O2. If CO is high make necessary adjustment. Check to ensure boiler, steam generator, or process heater light offs are smooth and safe.

Boiler Efficiency | How to balance steam loads efficiently

Aug 26, 2011 · If we generate the same additional 25,000 lb/hr steam in a steam generator, the additional fuel input (Table 1) is about 27.2 million Btu/hr on LHV basis. Another way to look at the efficiency of both boiler types is this: The HRSG generates an additional 75,000 lb/hr of steam with a fuel input of only 75.6 million Btu/hr (subtract the fuel

You can change this setting with your requirements. Now if the electrical sensor fails then the mechanical safety valve will open automatically.

Fire-Tube Boiler (~1800) The fire tube boiler, the oldest design, is made so the products of combustion pass through tubes surrounded by water in a shell. The furnace/flame volume can either be inside or external to the shell that contains the water. The upper steam capacity of fire tube boilers is about 20,000 Ibm/hr, and the peak pressure
