Introduction to the classification of boilers
1. According to the condition that the flue gas flows in the boiler, the water pipe boiler, the shell boiler (fire tube boiler), the water fire tube combined boiler 2, and the pot according to the way of placing:
Vertical boiler, horizontal boiler 3, according to the number of drums:
Single drum boiler , double drum boiler 4, according to the purpose:
Domestic boilers, industrial boilers, power station boilers, boilers for vehicles and ships 5, according to the medium:
Steam boiler , hot water boiler , steam-water dual-purpose boiler, organic heat carrier boiler 6, according to the installation method:
Quick-load boiler, assembled boiler, bulk boiler 7, according to fuel:
Coal-fired boilers, oil-fired boilers, gas-fired boilers, waste heat boilers, electric heating boilers, biomass boilers 8. According to the water cycle:
Natural circulation, forced circulation, DC boiler, compound cycle 9, pressure points:
Atmospheric pressure boiler, low pressure boiler, medium pressure boiler, high pressure boiler, ultra high pressure boiler 10, according to the number of boilers:
Single drum boiler, double drum boiler 11, according to the combustion inside or outside the boiler:
The internal combustion type boiler and the external combustion type boiler 12 can be classified into a natural circulation boiler, a forced circulation boiler, a direct current boiler, etc. according to the flow mode of the working medium in the evaporation system.
13. Classified by manufacturing level:
Class A, Class B, Class C, Class D, Class E (according to the pressure of the manufacturing boiler)
14. According to the export steam pressure:
Low pressure boiler (P<2.45MPa), medium pressure boiler (3.8<P<5.8MPa), high pressure boiler (5.9<P=12.6MPa), ultra high pressure boiler (12.7<P=15.8MPa), subcritical boiler (15.9< P = 18.3 MPa), supercritical boiler (22.115 <P < 30 MPa), ultra-supercritical boiler > 30 MPa.
Arbutin, also known as arbutin, chemical formula c12h16o7, is a component extracted from the leaves of Rhododendron. It can inhibit the activity of tyrosinase in the body, prevent the formation of melanin, thus reducing the deposition of skin pigment, removing stains and freckles. At the same time, it has bactericidal and anti-inflammatory effects. It is mainly used in cosmetics. Arbutin is mainly extracted from the leaves of bearberry. It can also be found in some fruits and other plants. Arbutin can brighten the skin and quickly penetrate into the skin without affecting the skin cells. Arbutin is the main component of a new type of burn wound medicine, which is characterized by rapid pain relief, strong anti-inflammatory effect, rapid elimination of redness and swelling, and rapid healing, No scars.
