Heat Balance Diagram or HBD for Thermal Power Station is the basically schematic representation of the whole steam cycle from Boiler to High Pressure (HP) Turbines Intermediate Pressure (IP) Turbines and Low Pressure (LP) Turbines to condenser to pumps to re-heaters and again to boiler. This diagram also contains some information of steam
Get A QuoteIn calculating a net economic heat balance the steam used by boiler auxiliaries such as steam-driven feed pumps, furnace jets, etc., must be taken into account, and the proportion of steam lost must be deducted from the total heat generated by the boiler. Fuel

Get A QuoteHeat balances are used in engineering for the analysis of thermal processes occurring in, for example, steam boilers, furnaces, and heat engines. A heat balance may be expressed in units of energy, such as joules or calories, or in percent of the total amount of heat per unit output, per hour of operation, per time period (cycle), or per kilogram of material used.
Get A QuoteSteam Heat Balancing & Venting. Steam can't go where air is. It's really that simple. Too many folks spend too much time thinking about what the steam is doing, when they should be thinking about where the air is going (or isn't). Because air is our enemy.
Get A QuoteHeat losses in the boiler if the heat is used only for warming fluid only. Total heat loss that may occur in boiler system can be calculated as formula below, so boiler efficiency calculation can be determined. Eloss total = Eloss-dfg + Eloss-H2 + Eloss-H2O + Eloss …
