Compared with the price of a traditional coal-fired boiler, the operation cost of a gas-fired boiler is relatively high. So, users need to consider the price and quality before purchasing a boiler. For a gas-fired boiler, the energy-saving performance is more important than the boiler price. One year is enough for a gas-fired boiler with good energy-saving performance to save the extra costs of the boiler proper. And, the gas consumption is an important indicator to measure the energy-saving performance of a boiler.
1. If the stop valve of the oil circuit is closed or the feeding of oil is insufficient and the oil filter is blocked, it is necessary to check that the valve in the oil circuit is open, the oil filter works normally and clean the filter screen of the pump.
2. If the oil temperature is low, viscosity is too high or the temperature of the oil fed by pump is too high, the oil temperature needs to be increased or decreased.
3. If the the domestic sewage treatment equipment oil pump breaks down, the oil pump is required to be replaced.
4. If the bearing of fan motor is damaged, it is necessary to replace the motor or bearing.
5. If the fan impeller is too dirty, it is required to be cleaned.
Purchasing a new boiler is a big decision for any company or organization. It means investing thousands of dollars in a piece of equipment you’ll be using for many years to come. Needless to say, it’s not a venture you should take lightly. You need to know ahead of time exactly what you should be looking for in a new boiler.
Any unusual noises should always be treated seriously.
One of the first things to check if a boiler is unusually noisy is the boiler's thermostat. If the thermostat is malfunctioning, water can become too hot and begin to boil, which could cause loud noises. If the thermostat is broken it may need to be replaced to prevent the water from heating up so much.
Another reason for a noisy boiler could be mineral deposits. As the water heats up inside the boiler, minerals may sink to the bottom of the tank and affect the heat exchange. This may create hot spots within the boiler in which water is overheated, leading to loud noises.
Low water pressure is also a concern that can result in loud noises. If water pressure is low, the boiler is tend to be overheat.
Water, which is the primary fluid inside the closed metal container of the industrial boiler, is heated to an atmospheric temperature and a pressure higher than the external one. Once the steam is generated, it advances through the pipes.
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. Hydraulic should be carried out at a defined pressure before the start of a boiler.2. Check if the pump inlets are open at the start of a boiler.3. Install an automatic ash removal system such as rotary valves in a boiler so as to prevent the accumulation of ash in a furnace or other equipment. The accumulation may result in the blockage or excessive heating of boiler parts resulting in its failure.4. Pump priming must be done at the start of the boiler.5. All loose and wrong connections must...
1. Primary air fan: after being heated by the air pre-heater, primary air enters into the wind chamber, then into the furnace through wind caps through the air distributor to fluidize particulate materials;2. Secondary air fan: after being heated by the air pre-heater, secondary air enters into the furnace through the secondary air ducts for complete combustion of fuels; the seal air, conveying air and fuel spreading air of the feeding device also adopt secondary air; 3. Circ...
