  • What is the safe pressure for a hot-water-heating system?

    The highest pressure the boiler should ever see is stamped on the boiler tag - Usually 30- or 50-psi. The pressure the system is designed to operate at is usually 12- to 25-psi for a two-story house, and 18- to 25-psi for a three-story house.

  • Chapter 2 Boiler 101: typical NYC residential heating system

    If the temperature of the boiler water falls below 180°F, a hot water boiler's controller will initiate combustion. In an oil-burning boiler this is accomplished by a fuel pump drawing the liquid fuel from the storage tank through a filter and pumping it into the burner assembly located in the combustion chamber.

    This article covers the four most common ways to "destroy a boiler," including fuel explosions, low-water conditions, poor water treatment, and improper warm-up. The design and construction of power and recovery boilers represent one of the largest capital expenditures in the industrial utilities arena.

    If your building is burning #6 fuel oil, the strainers MUST be cleaned at least once a day. Although highest in heating value and lowest in price, even the best quality #6 fuel oil contains a high percentage of particulate matter and impurities. If your system is burning #4 fuel oil, the strainers will require slightly less maintenance.

    Furnace pressure in a balanced draft furnace is always kept negative, and in pressurized furnace it is positive. Present days designers adopt balanced draft furnace for all solid fuel fired boiler, however there are installations of pressurized furnace even in the case of solid fuel fired boilers.

  • What is the pressure inside a boiler? What is the effect

    Your question is a bit too broad because boiler pressure (and temperature) depends on a variety of factor such as fuel (wood, coal, fuel oil etc), boiler area and configuration, material, and downstream requirement (engine pressure requirement, turbine requirement, chemical reactor requirement and other end-user requirement).

    If the plant has only one steam generator (boiler), uses a single fuel, and has a single steam pressure level, it is relatively easy to assign a cost to the steam. However, in most cases, there are multiple steam sources and multiple fuels. There are also multiple steam pressure levels with multiple paths by which the steam pressure is reduced; for example, steam pressure can be reduced via pressure-reducing
