Industry boiler is an important thermal power device, which is widely used in factory power, building heating, people's life and other aspects, with a large demand and a wide variety. According to the different flue gas passes, gas-fired boilers are divided into two-pass and three-pass boiler structures. Here, ZOZEN Boiler focuses on the structure and process principle of the common three-pass boiler.
The first pass: after the fuel is atomized by the burner, the formed torch is filled i...
Hot water boiler is a kind of thermal equipment that uses natural gas, oil and biomass as fuel to heat water to the rated temperature. It is widely used for heating, bathing and domestic hot water in hotels, schools, hotels, communities and other enterprises and institutions. Generally, pressurized hot water boiler is widely used, so what does pressure-bearing hot water boiler mean?
In a pressure-bearing hot water boiler, the meaning of pressure is that the internal pressure of the boil...
When the boiler flue gas is saturated wet flue gas, the flue gas contains a large amount of water vapor. At this time, if the flue gas is directly discharged from the chimney and enters the low-temperature ambient air, and the saturated humidity of the ambient air is relatively low, the water vapor in the flue gas will condense to form wet plumes, which is often called "white smoke".
The water in the flue gas of the boiler is produced during the combustion of the hydrogen element of hyd...
Commonly used dust removal equipment of SZL boiler includes multi-tube dust collector, wet scrapper and bag filter.
1. Multi-tube dust collector: XTD type vertical ceramic multi-tube dust collector has the advantages of wear-resistance, high temperature resistance, corrosion resistance, low cost, etc. Its collection efficiency is not less than 95%, resistance is not higher than 900Pa and mainly removed dust granularity is greater than 20um.
Design, manufacture and acceptance of multi-t...
a) Boiler hot water system design should meet the requirements of Code for design of boiler plant GB50041.
b) Steam collecting device should be installed in the highest position of hot water system and the position where is easy to collect steam. Reliable constant pressure measures and circulating water expansion device should also be set to ensure that pressure in system is not lower than the corresponding saturation pressure of outlet water temperature plus 20 °C so as to avoid boiler wat...
The fuels of ZOZEN WNS gas/ oil fired boiler are mainly oil and gas. Oil and gas fuel are supplied to burner by piping conveying.
Oil fuel supply system mainly includes: oil storage tank, daily-used oil tank, oil filling pump and oil filling pipelines.
Oil storage tank: This is used to store oil for boiler combustion. Small capacity oil storage tank usually adopts buried layout and buried tank should be reliably fixed and be guaranteed not be floated by surface water. Oil tank that volume is m...
Industry boiler usually adopts ion-exchange method for water softening, dealkalization and desalination. There are two kinds of water softener- automatic operation and manual operation.
Water softener specification, resin loading capacity and salt consumption are directly related to raw water hardness, so it is crucial to select correct water softener according to raw water situation.
According to its working control method, full-automatic water solener could be divided in two typ...
In recent years, the contradiction between energy supply and demand and environmental pollution has become increasingly prominent, and all small coal-fired boilers with backward technology have been transformed into natural gas boilers with clean energy. The flameout of natural gas boiler is one of the common faults of boiler, so how to deal with the flameout problem?
Trouble shooting of natural gas ignition and flameout in boiler
It is necessary to check the causes of the natural gas ignition...
