All boilers, whether hot water or steam, depend on fuel to run. The heating process is initiated when the burner heats or evaporates the water inside it, which is ultimately transported via pipe systems. Hot water boilers rely on pumps to move the heat through the system, while steam boilers are transported with the pressure generated in the heating process. Eventually, cooled water or condensed steam is returned back through the pipes to the boiler system so that it can be heated once again. While the boiler is generating energy in the form of heat, flue gases, a byproduct of this process, are removed through a chimney system - which is why regulating the emissions of industrial boilers is taken very seriously.
In a water tube steam boiler, unlike a fire tube, water circulates inside the tubes. The heat that is generated and the combustion gases that surround the tubes heat the water that circulates inside them. Many water-tube boilers operate according to the principle of natural water circulation.
The capacity of this type of boiler can be enhanced by increasing the number of tubes in the boiler.
Steam boilers with a low NOx system are specially designed to minimize the environmental impact with the production of dry saturated steam. This type of boiler incorporates a stainless steel economizer with a cross flow integrated within the boiler and that, consequently, allows to reach maximum efficiency.In addition, it has a natural gas burner with low NOx emissions.
Biomass steam boilers recover the heat generated during the biomass combustion process to heat the water in the boiler exchanger circuit. The hot water is then diverted to the heating circuit.
Occasionally it is necessary to remove the ashes generated by biomass combustion and clean the burner.
1. Rational air distribution, supply sufficient and rational air by region; 2. Appropriate furnace temperature;3. Suitable air turbulence and mixing in furnace;4. Fuels remain long enough on chain grate and in the furnace;5. Keep a reasonable distance between the fuel hopper and the flame fronts to avoid igniting fuels in the hopper.The biomass-fired boilers are optimally designed according to the characteristics of different biomass fuels. ZOZEN will customize the biomass-fired boiler for ...
Question details (Specific performance):Biomass environmental protection and energy saving fuel made of straw and livestock etc., their combustion is not full. Answer: The cause of the problem:1. Air quantity is insufficient or too big.2. Outer flame position is not proper.Troubleshooting:1.Sufficient temperature: sufficient combustion of biomass boiler needs high temperature, combustion rate is proportional to the temperature, to raise the temperature as much as possible but guarantee there is no slagging.2. Proper air volume. If the air volume is too large, it will reduce the temperature of the furnace and increase the incomplete combustion of fuel. If the air volume is insufficient, the combustion efficiency will be reduced, and the waste of fuel will also increase the emission of smoke.3. Sufficient mixing of fuel and air. During the burning stage of biomass boilers, the sufficient mixing of air and fuel should be ensured and the disturbance should be strengthened during the burnin
(Question Details) Specific Performance:Broken coal is one of the most common failures of the coal feeder. The coal feeder is the lifeline of the boiler. Its normal operation is the basic guarantee for the normal and stable operation of the boiler, because it’s common occurrence that the coal feeder breaks the coal, especially when multiple coal feeders broken coal simultaneously, the improper handling resulting in overheating, explosion, coking, shutdown and other failures. Answer:cause of failure:(1) The particles of fluidized bed boiler fuel are coarse, but the fine particles in the fuel have a large amount of moisture. It is very easy to bond, resulting in the clogging of coal bunker and coal feeder.(2) Coal particles are jammed and squeezed in the coal feeder, causing the coal feeder chain to break.(3) Impurities in coal, such as woven bags and tree blocks, enter the coal feeder, causing coal feeders to jam, blockage, trip and break pins. Troubleshooting:(1) Fluidized Be
