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...
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.
As we all know, the transportation cost is generally related to the weight of the boiler, so how much does a 4-ton boiler weigh? How much steel does it contain? According to the fuel, 4-ton boilers are divided into 4-ton gas-fired boilers and 4-ton coal-fired and biomass-fired boilers. The amount of steel used for small-scale coal-fired and biomass-fired boilers is generally 5-7 times of the boiler output (excluding the front and rear arches), and about 25 tons for 4-ton boilers.
The principle of boiler economizer is that the flue gas from the boiler tail enters the boiler economizer, and the water in the boiler economizer absorbs the temperature in the flue gas through the finned tube and then returns to the boiler, which is equivalent to raising the boiler feed water temperature and reducing the energy consumption when the boiler output is certain.
Boiler economizer is generally installed at the tail of boiler flue. Due to the different principles and boiler equipment...
The boiler needs to blow off every day, and it is advisable to reduce the blowdown to below the boiler water level every time.
The boiler water level meter can record the boiler water level in detail, and the water level has a great influence on the boiler, so we should ensure that the boiler water level is within the normal range.
When the gas-fired boiler is running, there will be pressure inside, which can provide sufficient power for all kinds of production equipment. However, if the press...
Different users have different requirements for boiler configuration. For example, some users need NOx emission less than 30mg/Nm3, and some users only need it less than 80mg/Nm3. The better auxiliary equipment configuration is used, the price of boiler will naturally rise.
Different users have different requirements for the configuration of the whole boiler system, and the brand and quantity of auxiliary machines also affect the price. The better the brand, the more expensive the price. For ex...
(1) The boiler and all auxiliary equipment are installed, and all tests such as ball passing test, hydrostatic test and air tightness test are qualified.
(2) All rotating devices, feed water pumps, condensate pumps, salt solution pumps, blowers and induced draft fans for coal conveying, combustion and ash removal are qualified for trial operation.
(3) The fuel and water supply are guaranteed, the steam, water and flue gas piping system are normal, and the connection unrelated to the boiler to ...
The first technical problem is the reconstruction of boiler body:
The coal-fired boiler is mainly grate firing boiler. For small water-tube hot-water boilers, it may lead to the water temperature at the outlet of the riser exceeding the limit or overheating boiling or even vaporization. For shell-and-tube boilers, the rising flue gas temperature at the furnace outlet will make the working conditions of the tube plate worse, thus causing cracks and leakage of the tube plate.
