Boiler heat supply refers to the continuous heat production per unit time when the rated parameters, rated flow, designed fuel and efficiency are guaranteed. There are many ways to express the boiler heat supply, and there are certain conversion standards.
Conversion between heat supply units: 1t/h = 0.7mw = 600,000 kcal/h =720KW
According to the conversion standard, a 5-ton boiler is also a 3.5MW boiler. Therefore, for the users who need 3 million kcal boilers, we recommend WN...
The fuel of gas boiler is mainly natural gas, petroleum gas, gas, etc. The air energy water heater is powered by electric power and air energy to maintain the operation of the machine.
The boiler chimney is one of the essential facilities in the process of building a gas boiler room. Its main function is to provide ventilation for the hot flue gas or smoke emitted by the boiler. Usually, when making the chimney of gas boiler, choose the vertical structure as much as possible to ensure the gas flow smoothly, and the sucked air enters the so-called chimney combustion or stack effect.
Many people will consider the heating efficiency and heating area when choosing and using boiler equipment. In fact, how many square meters a ton of hot water boiler can heat has a certain relationship with the type and capacity of the equipment.
Generally speaking, the heat to be absorbed by 1kg of water is 1kcal for every 1℃ increase, it is concluded that the heat supply of 1 ton (0.7MW) boiler is 600,000 kcal. Therefore, how much boiler is needed to heat 20 tons of water from 15℃ to 40℃ for ...
What is a large-scale steam boiler? Generally, large-scale steam boilers mainly refer to steam boilers over 75 tons. Large-scale steam boilers can be divided into oil-fired boilers, gas-fired boilers, coal-fired boilers and biomass-fired boilers according to fuel. At present, the number of large-scale steam boilers used in the industry is still relatively large, among which they are used in chemical industry, food industry, industrial and mining enterprises and building materials enterprises.
When purchasing the gas-fired boiler, the enterprise will generally require to visit the boiler factory at the later period of boiler procurement. Via visiting the boiler factory, the enterprise can have a comprehensive understanding of the operation process, production scale, product quality details, corporate management level, factory shipment and other information of the boiler factory, and can further understand the service quality of the boiler manufacturer.
Economizer
Increase the heat exchange area of the boiler economizer. For example, adopting the economizer whose actual internal area is 1-2 times larger than the ordinary can effectively reduce the flow rate of flue gas, improve the heat exchange efficiency and lower the exhaust gas temperature.
Air preheater
An air preheater is installed with the connected pipe behind the economizer, which can effectively increase the air temperature for supporting the combustion, improve the fuel ignition ...
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 ...
