The coal-fired boiler has always been one of the important boiler types in the industrial production and its operating costs and capacity play an important role in the enterprise operation.
Understanding Nitrogen Oxides (NOx) Formation:
Nitrogen oxides, commonly referred to as NOx, are harmful pollutants formed during the combustion process in gas boilers. Their generation is primarily linked to the combustion temperature and the presence of nitrogen:
Thermal NOx: Formed at high temperatures, typically above 1,300°C (2,372°F). At these temperatures, oxygen molecules (O2) in the air dissociate into individual oxygen atoms, which then react with nitrogen (N2) present in the...
The common methods for boiling the gas-fired boiler:
1. Sodium carbonate (Na2CO3) or trisodium phosphate (Na3PO412H2O) and other drugs are used, and the dosage is calculated as per cubic meter of boiler volume, with the former being 5 kg and the latter being 3 kg;
2. Close the front manhole, hand hole and main steam valve (main water outlet valve), open the manhole of the upper drum, inject the prepared solution into the drum at one time, then close the manhole and open the emptying valve...
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...
Boiler environmental factors are an important aspect of managing boiler control safety, and users need to correctly identify boiler environmental factors. The environmental factors of different boiler rooms are different. Here we mainly introduce the environmental factors of gas boilers.
Gas boiler environmental factors
1, Lighting lamps, short-circuit, leakage cause fire, discarded
2, Burn the boiler, which produces harmful gases
3, Sanitary cleaning, waste cleaning tools, garbage
4, Boile...
The thermal efficiency of boiler refers to the percentage of effective heat in the heat delivered by fuel. The thermal efficiency of boiler is one of the important indexes to reflect the energy efficiency of boiler. Many users often ask, what is the general thermal efficiency of natural gas boilers? In this page, ZOZEN Boiler will analyze the thermal efficiency of natural gas boiler and introduce the calculation method of thermal efficiency.
What is the general thermal efficiency of nat...
Low-carbon condensing gas boiler takes clean energy natural gas as fuel, and uses high-efficiency flue gas condensation waste heat recovery device to absorb sensible heat and latent heat released by steam condensation in the tail of the boiler, so as to achieve the purpose of improving boiler thermal efficiency and saving energy, thereby reducing carbon emissions.
Low-carbon gas-fired boiler recovers the energy from the hot flue gas (generally around 140℃) emitted by the boiler through ...
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.
