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.
Because gas-fired hot water heating boiler is used for central heating, after the boiler is ignited, it needs to go through a series of processes such as furnace heating, low-temperature operation, heat exchange and so on, to gradually heat up the central heating. After ignition of gas-fired hot water heating boiler, furnace heating is a necessary preparation work at the initial stage of heating every year, and this process takes about 3-5 days to complete.
Chain grate boiler is a very mature boiler type, which has the characteristics of simple operation and management and easy mastering, and is widely used in various industries.
1. Enterprise qualification
Which manufacturer is good, enterprise qualification is the first. On the whole, enterprise qualification reflects the enterprise's personnel quality, technology and management level, engineering equipment, capital and benefit, contract management ability and other aspects. Genera...
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 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.
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 ...
The fuel cost of 10 tph electric boiler: 7,100 kilowatt-hour is multiplied by the local industrial electricity unit price which is nearly 1 RMB, so we can get 1 RMB/kWh and the fuel cost is about 7,100 RMB per hour.
