(Question details) specific performance:The gas boiler is powered on, press start, the motor does not turn. Answer: Fault reason:1. Insufficient pneumatic locking.2. The solenoid valve is not sealing, and there is air leakage at the joint. Check the lock.3. The thermal relay is open.4. At least one of the conditional circuits is not valid (water level, pressure, temperature and to check whether the program controller is energized to start). Troubleshooting:1. Adjust the air pressure to the requested value.2. Clean or repair solenoid valve pipe joint.3. Check whether the component is damaged and motor current by reset.4. Check whether the water level, pressure and temperature exceed the limit.ZOZEN gas-fired boiler adopts automatic control to control the operation, combustion, water level, temperature and steam pressure. In case of such problems, the system will automatically prompt the error code.
There are several ways to estimate the thermal efficiency of gas-fired boilers:
1. Direct method: This method involves measuring the amount of fuel consumed and the amount of heat produced by the boiler. By comparing these two values, it is possible to calculate the thermal efficiency of the boiler.
2. Indirect method: The indirect method involves measuring various parameters such as flue gas temperature, ambient air temperature, and fuel consumption, and then calculating the t...
Combustion is a process which needs constant air supply for its survival, but as we move up the earth i.e. at higher altitudes, things aren’t the same as they used to be at sea level. Due to decreased air density at higher altitude, it will consume the same volume of air but will not consume the same mass of air.
This results in less fuel consumption & less steam generation rate. Due to the reduction of mass flow of gases through tubes of a steam boiler, convective heat transf...
Biogas is the mixture of gases produced by the breakdown of organic matter in the absence of oxygen (anaerobically), primarily consisting of methane and carbon dioxide. Biogas can be produced from raw materials such as agricultural waste, manure, municipal waste, plant material, sewage, green waste or food waste. Biogas is a renewable energy source.
Biogas is a byproduct of the decomposition of organic matter by anaerobic bacteria. Biogas is typically composed of 60% methane and 40% CO2...
According to the Wikipedia, Second-generation biofuels, also known as advanced biofuels, are fuels that can be manufactured from various types of non-food biomass. Biomass here means plant materials and animal waste used especially as a source of fuel.
Advanced biofuels are renewable fuels derived from renewable biomass that achieve a fifty percent greenhouse gas emissions reduction over conventional biofuels. The definition of advanced biofuels includes cellulosic biofuels, biomass-bas...
People assume that owning a biomass boiler is no different from owning its less environmentally friendly cousins, the oil and gas boilers. Nothing could be further from the truth, and it is this very misconception which leads to abuse and neglect of the maintenance that a biomass boiler needs, if it is to retain its environmental and economic saving potential. This is especially true given the tendency of many installers to skimp on providing the proper support services and education to their customers.
A condensing boiler can condense the water vapour in the flue gases and withstand the corrosive and acidic qualities of the flue gas condensate. Although most boilers can condense the flue gasses, only boilers that have heat exchangers constructed from materials able to withstand the corrosion should be used in condensing application. Condensing boilers with primary and secondary heat exchanger do not work well as they are not able to fully condense and defeat the purpose of using a condensing boiler. Also, boilers with this arrangement are prone to condensation in the primary heat exchanger at lower firing rate which can cause damage to the heat exchanger.
One of the biggest issues related to natural gas explosions is that in the industrial world, people just don’t understand that natural gas piping repairs are different from other piping repairs.
