The pulverized coal is blown into the boiler where it mixes with the supply of air for combustion. Heat is transferred to steam pipes located in the top region of the boiler, these being initially fed with hot water from the boiler feed pump; the hot water then gets converted to steam at high temperature and pressure.Get Price
Put simply a heat pump takes the available heat from the ground or air surrounding a property and increases it to a more useful temperature for use in the home. This renewable source of heat can be used to create warm air or water (for space and central heating) as well as hot water (for both central heating and domestic hot water supply).Get Price

Effective heating surface is defined as the flat projected area of tubes and extended surface integral. With tubes exposed to direct radiation (only the first row of tubes in flue gas passes exposed to direct radiation should be counted for calculation of flat projected surface and the refractory covered surface should not be counted).Get Price
It is proportional to the outer surface area of the boiler and is usually 200-300 W/(m2K) for a well-insulated boiler having its outer surface temperature below 55 °C. Another possibility to determine the heat transfer losses to the environment is to use a table from the DIN 1942 standard, presented in table 2.Get Price
