1. The control system is equipped with a special computer controller, which makes the boiler running clear and easy to operate.
2. The burner is controlled by full-automatic program, and in case of failure, the burner stops automatically.
3. The boiler body is designed with reasonable structure, and the top is equipped with air vent. The boiler works under normal pressure and is far away from explosion danger. The full wet back three-way structure and corrugated tank design are adopted. The flue gas process is long, the temperature of exhaust gas is reduced, the heat transfer coefficient is increased, and the equipment life is prevented from being reduced due to the expansion and contraction of metal.
The thermal oil heater is a heater that uses heat medium oil as medium for heat transfer. The low-pressure and high-temperature heating can be realized by the utilization of the high-temperature characteristics of heat medium oil.If there is too much moisture in the low-temperature heat medium oil, there will be pressure fluctuations, which will cause some other problems. In addition, if the heat medium oil does not flow in the furnace owing to the stop of pump, the oil temperature will rise and exceed the limit value, which not will greatly affect the service life of the heater and cause the deterioration of the heat medium oil.
Generally, there is moisture in heat medium oil. And, the moisture will be evaporated during the heating process of the oil. If the water vapor is not discharged from the thermal oil heater, it will cause the fluctuation of heat medium oil pressure. However, the oil-gas separator can separate the water vapor from the heat medium oil and discharge it from the heater, which ensures the stable oil pressure.
If the circulating pump of a thermal oil heater stops working suddenly. Then, some measures should be taken immediately to remove the fire source. If not, the stop of circulating pump will cause coking in the oil tube, which will shorten the service life of the heater.
1. The storage tank is used to store the heat medium oil of the heating system;
2. The storage tank is used to receive the overrunning heat medium oil；
3. The storage tank is used to supplement heat medium oil for the heating system;
4. The storage tank should be placed at the lowest position of the system;
5. A firewall should be placed between the storage tank and the thermal oil heater;
6. The storage tank should be operated at a low liquid level.
The selection of a burner of the gas-fired thermal oil heater should be determined according to the boiler proper structure and fuel characteristics and in combination with the actual conditions and requirements. In addition, this kind of boiler can adopt a waste heat recovery device to improve thermal efficiency and reduce heat energy loss.
Although biomass-fired boilers are environment-friendly boiler products, there are also some situations that biomass-fired boilers can’t be used. Main reasons as follows:
Fuel restrictions: The fuels that contain synthetic compounds can’t be used as the fuel of a biomass-fired boiler, such as waste wood furniture, waste paper, production and domestic waste.
A steam boiler plant must operate safely, with maximum combustion and heat transfer efficiency. To help achieve this and a long, low-maintenance life, the boiler water can be chemically treated.
The operating objectives for steam boiler plant include:
Safe operation.
Maximum combustion and heat transfer efficiency.
Minimum maintenance.
Long working life.
The quality of the water used to produce the steam in the boiler will have a profound effect on meeting these objectives.
