Explosion-proof door structure: boiler blast doors have Slat (also indemnity for the swing) and blasting membrane two kinds. Slat blast doors, also known as swing-proof door, multi-device to the furnace wall of the combustion chamber. Into its mounted position is inclined and vertical two, by the door, the door and the hinge member and the like components. The door frame and multi-cast iron round or square, the width of their mutual contact surface generally is 3 ~ 5mm, and should ensure tight. The door is coated with a heat-resistant concrete, which limit the pressure according to a desired thickness value has been calculated or determined experimentally. When the gas explosion in the furnace or the flue of the boiler, the door is automatically turned about the shaft relief, and then shuts itself down. Sealing pressure of the vent door from the inclination angle (usually not more than 30 °) or the downward pressure created by the weight of a weight is obtained.
Our emphasis on increasing green, local governments also boiler operation produces nitrogen oxides and smoke emission requirements become more stringent. Fast boiler followed by the national trend of development, deepening of cleaning boiler product design and development. Lulu as a representative of business development of the national beverage, and hope to find a set of boiler energy conservation and clean in one, for drink production process of fermentation, sterilization, drying, curing and other processes. After many visits and market research, in October 2017 and entered into boiler fast boiler purchase contracts, purchase two 10 tons of steam and a whole 20 tons of steam condensing 2 types of steam boiler wiki. The two sides this cooperation is the other quality fast condensing gas boiler highly recognized, has proved a powerful strength fast boiler in the boiler production and service of gas condensate from the side.
Why after normal boiler outage to take natural cooling? A: The steam has a certain pressure at a certain saturation temperature, when the pressure change, the saturated water and saturated steam temperature change accordingly; shutdown if the boiler pressure drops too quickly, the saturated water and saturated steam temperature, and dramatically drop. Due to the high rate of change of pressure saturation temperature at a lower pressure, because the upper wall in contact with the drum the saturated steam, saturated with a lower water contact. Thermal conductivity of water is relatively large, the heat storage drum is quickly transferred to the water in the lower wall, the lower the temperature of the drum, close to the saturation temperature at the new pressure after the pressure drop; and poor heat transfer drum upper wall, maintained high temperature, the wall temperature is higher than the upper drum wall temperature, the faster the vapor pressure drop, the greater the temperature difference between the upper and lower walls drum.
Sep 24, 2018 · Various types of valves are used in the boiler, depending on the application. 1. Gate Valves 2. Globe valves 3. Globe needle valves ( Regulating valves) 4. Control valves.Learn More
Oct 27, 2017 · To produce steam of course. Steam has all sorts of uses. It can be used for building heat. It can ironically also be used for building cooling by using a steam absorption chiller.Learn More
Boilers are used in power plants in order to produce high pressured steam, so that the plant can generate electricity. The process that does this is known as the Rankine cycle . The boiler takes in energy from some form of fuel such as coal, natural gas, or nuclear fuel to heat water into steam .Learn More
A high pressure watertube boiler is a type of boiler in which water circulates in tubes heated externally by the fire. Fuel is burned inside the furnace, creating hot gas which heats water in the steam-generating tubes. In smaller boilers, additional generating tubes are separate in the furnace, while larger utility boilers rely on the water-filled tubes that make up the walls of the furnace to generate steam. High Pressure Water Tube Boiler: The heated water then rises into the steam drum. HereLearn More
Feb 28, 2014 · Steam vent types: 2 pipe steam vents vs 1 pipe steam heat system vents: this article describes the differerent types of vents used on two pipe and one pipe steam heating systems and explains why a 2-pipe steam heat system will generally require different vents at different locations fron a 1 pipe system.Learn More
May 01, 2011 · It may be debated who developed the first steam-generating boiler; however, most will agree that George Babcock and Steven Wilcox were two of the founding fathers of the steam-generating boiler. They were the first to patent their boiler design, which used tubes inside a firebrick-walled structure to generate steam, in 1867, and they formed Babcock & Wilcox Company in New York City in 1891.Learn More
All the heat losses cannot be fully recovered but they can be reduced to a large amount thereby improving your steam boiler efficiency which will save you a lot of money. Efficiency of Boiler & Heat Losses. There is various type of heat losses in the boiler.Learn More
Most steam boiler systems in homes are either one-pipe or two-pipe systems. One-pipe (or single-pipe) systems use the same pipes to deliver steam to the radiators and to return water to the boiler. The steam rises up and the water falls down through the same pipes.Learn More

The steam generator or boiler is an integral component of a steam engine when considered as a prime mover.However it needs be treated separately, as to some extent a variety of generator types can be combined with a variety of engine units.Learn More
The steam boiler is an old convection heating technology dating back over 200 years and is most commonly found in old homes. Because steam boilers operate at a higher temperature than hot-water boilers, they are inherently less efficient than their hot-water cousins and are more finicky to operate.Learn More
Boiler configurations. There are two main types of steam boilers, both of which are uniquely specific, known as fire tube and water tube boilers. The configurations of these boilers control how they operate and affect the entire steam boiler system. In a fire tube boiler, there are metal rods that pass through the center of the water vessel.Learn More
Boilers generally have 2 or 3 pressuretrols: a manual-reset pressuretrol, which functions as a safety by setting the upper limit of steam pressure, the operating pressuretrol, which controls when the boiler fires to maintain pressure, and for boilers equipped with a modulating burner, a modulating pressuretrol which controls the amount of fire.Learn More
WorkingEdit. A boiler with both steam drum and mud/water drum is called a bi-drum boiler and a boiler with only a steam drum is called a mono-drum boiler. The bi-drum boiler construction is normally intended for low pressure-rating boiler while the mono-drum is mostly designed for higher pressure-rating.Learn More
