Different steam pressures correspond to different steam temperatures.
1. The steam temperature of low-pressure boiler is mostly saturation temperature or not higher than 400℃.
2. The outlet pressure of medium-pressure boiler is 3.8 ~ 5.4 MPa, and the commonly used steam temperature is 450℃.
3. The outlet pressure of sub-high pressure boiler is 5.4 ~ 9.8 MPa, and the common steam temperature is 540℃.
Boiler furnace is a three-dimensional space surrounded by furnace walls, which is used for burning fuel. The function of the boiler furnace is to ensure that fuel is burned out as much as possible, and to cool the flue gas temperature at the outlet of the furnace to the temperature allowed by the safe operation of the convection heating surface.
Reasonable arrangement of igniters in gas-fired boiler can not only obtain ideal ignition effect, but also save ignition fuel. However, due to the different types of fuel and burner, the igniter arrangement of gas boilers is different.
Ash accumulation on the heating surface.
The scaling and ash deposition on the water-cooled wall of the furnace and the ash deposition of the superheater, convention tube bundles, economizer and preheater can increase the thermal resistance of the flue gas, weaken the heat transfer, lessen the cooling effect of the flue gas and increase the exhaust gas temperature of the gas-fired boiler.
Too high excess air coefficient.
Under normal circumstances, as the furnace outlet excess...
When it refers to how to reduce the procurement cost of industrial boilers, many corporate users will be first to take measures to effectively reduce the related costs involved in the boiler procurement process, such as the boiler equipment cost, transportation cost, loading and unloading cost, insurance cost, installation and commissioning cost, labor cost, acceptance and inspection cost.
In boilers, economizers are heat exchange devices that heat fluids, usually water, up to but not normally beyond the boiling point of that fluid. Economizers are so named because they can make use of the enthalpy in fluid streams that are hot, but not hot enough to be used in a boiler, thereby recovering more useful enthalpy and improving the boiler's efficiency. They are a device fitted to a boiler which saves energy by using the exhaust gases from the boiler to preheat the cold water used to fill it (the feed water).
Today, there are two main types of green boilers used in different industries: biomass boilers and condensing boilers. Each of these operates in completely different ways to reduce your carbon footprint.
Biomass Boilers
Biomass boilers operate by burning wood and other renewable organic materials to produce heat. There are automatic biomass boilers that control the amount of air and fuel that is used, making them even more efficient. To keep this boiler running, owners will need ample ...
According to the Wikipedia, Second-generation biofuels, also known as advanced biofuels, are fuels that can be manufactured from various types of non-food biomass. Biomass here means plant materials and animal waste used especially as a source of fuel.
Advanced biofuels are renewable fuels derived from renewable biomass that achieve a fifty percent greenhouse gas emissions reduction over conventional biofuels. The definition of advanced biofuels includes cellulosic biofuels, biomass-bas...
