Black smoke in gas-fired boilers is typically an indication of incomplete combustion, where the fuel is not being burned efficiently. This can happen due to several reasons:
Poor Air-to-Fuel Ratio: The most common cause of black smoke is an improper balance between the air and fuel. Too much fuel or insufficient air leads to incomplete combustion, resulting in black smoke due to unburnt carbon particles.
Dirty or Clogged Burners: Over time, burners can become dirty or clogged, affecting the ef...
Boiler efficiency refers to the percentage of boiler effective utilization heat to boiler input heat per unit time, that is, the percentage of effective utilization heat per standard cubic meter of gas fuel. ZOZEN gas-fired boilers all adopt large furnace design, with the efficiency as high as 98% and NOx emission as low as 30mg/Nm3.
Coking and dust accumulation on heating surface. Whether it is slagging and ash deposition on the water wall of the furnace or ash deposition on the superheater, convection tube bundle, economizer and preheater, the measured thermal resistance of flue gas will increase, and the deterioration of heat transfer will worsen the cooling effect of flue gas, resulting in an increase in the temperature of boiler waste gas.
Removal of metallic scale and corrosion products generally requires chemical cleaning. Acid or chelant cleaning procedures vary greatly depending on individual circumstances. Chemical cleaning can improve the boiler heat rate and reduce the number of tube failures. It typically improves the stability of boiler chemistry.
Boiler feedwater treatment system includes two parts: pre-desalination system and ion exchange desalination system.
The pre-desalination system includes ultrafiltration system, reverse osmosis system, dosing system, chemical cleaning system, compressed air system, etc.
The ion exchange desalination system includes ion exchange system, acid-base regeneration system, compressed air system, wastewater neutralization treatment system, etc.
The boiler feedwater treatment methods ar...
Generally, small gas-fired hot water boilers are between 0.7 MW and 14 MW, and the output of boilers is different, so the prices are different. Different pressures require different techniques, materials and pressures. The higher the pressure, the higher the price.
Under the strict control of the policy, a wave of new energy boiler fuels and environmental protection transformation of combustion equipment has been launched in various coal-forbidden areas, which has brought new opportunities to the new energy boiler fuel market. What are the new energy boiler fuels?
Hot-water boiler is a kind of thermal equipment that uses the heat energy released by fuel combustion or other heat energy (such as electric energy, solar energy, etc.) to heat water to the rated temperature. According to different fuels, hot water boilers can be divided into gas-fired hot water boilers, oil-fired hot water boilers, biomass-fired hot water boilers, and coal-fired hot water boilers. How to choose hot water boiler? We will focus on the heating, pressure and thermal efficiency of hot water boiler.
