Before purchasing a set of oil-fired boiler, users should not only care about the quality and price of the boiler, but also consider the thermal efficiency and operating cost of the boiler. Oil-fired boiler is a kind of large-scale industrial equipment, and its energy-saving effect determines the operating cost of a ton of oil-fired boiler, so enterprises should pay attention to it.
Generally speaking, the operating cost of one ton oil-fired boiler mainly includes fuel cost, electricity cost, w...
Most petroleum products can be used as fuel, and boiler oil is a kind of refined oil, which is widely used in power plants and industrial boilers. Boiler oil is mainly made of petroleum cracking residue oil and straight-run residue oil, which is characterized by high viscosity and high content of non-hydrocarbon compounds, gum and asphaltene.
The formula of boiler oil mainly includes the following indicators: viscosity of the boiler oil, sulphur content, density, flash point, water content and ...
Boiler output refers to the maximum continuous output of the boiler under rated parameters (pressure, temperature) and certain efficiency. For steam boilers, it is called rated evaporation, and the unit is tons/hour; For hot water boilers, it is called rated heat production, and the unit is MW.
What are the main factors affecting the output of gas-fired boilers? According to the analysis of ZOZEN Boiler engineers, there are many reasons for the insufficient output of gas-fired boilers,
...
Boiler efficiency refers to the percentage of boiler effective utilization heat to boiler input heat per unit time, that is, the percentage of effective utilization heat per standard cubic meter of gas fuel. ZOZEN gas-fired boilers all adopt large furnace design, with the efficiency as high as 98% and NOx emission as low as 30mg/Nm3.
With the rapid development of economy, the demand for industrial boilers in modern enterprises is increasing. Because of the particularity and complexity of industrial boilers, we must understand the problems clearly before purchasing. According to the question "what is the main function of boiler superheater", ZOZEN Boiler will answer the doubts first.
There’s a lot to carefully consider when you’re upgrading or replacing your facility’s equipment. Thermal oils tolerate higher temperatures than water-based formulas without boiling or unduly increasing system pressure.
Thermal fluid heating, and thermal oil systems, in particular, have several advantages. These advantages include:
Efficient industrial heating is important for a variety of reasons – both within your facility and its daily operations, a...
The gas-fired hot water boiler heats up quickly and has the high thermal efficiency. It is widely used in the heating industry and production. What are the maintenance methods of the gas-fired hot water boiler?
For same energy output when energy input is lesser efficiency increase. When maximum heat energy is generated from coal or losses in heat transfer are reduced efficiency increase. Coal in boulder size is burnt combustion may not be complete. There will be more unburnt coal. As per coal chemistry and as per boiler flue gas velocity as designed best coal size for full combustion is designed. Maximum crushed coal is also not the best. Then there will be more coal dust. According to general design in various technologies pulverized coal give best combustion for fbc boilers. For cfbc boilers generally crushed coal size is 6 mm.
When you achieve best combustion mean this is main contributor for increase in efficiency. Boiler design, heat transfer, flue gas velocity, heat losses, are other factors for efficiency.
