Strictly control the operating pressure of the environmental thermal oil heater, and do not exceed the specified range. Once there is a trend of exceeding the specified upper limit, immediate measures should be taken.
The environmental thermal oil heater has the characteristics of high temperature and low pressure, which can work under lower pressure and produce high temperature.
The environmental thermal oil heater refers to a boiler heated by heat transfer oil. Heat transfer oil, also known as organic heat carrier, has been used as an intermediate heat transfer medium in industrial heat exchange for more than 50 years.
The economizer of condensing gas-fired boiler can be installed in the flue of the current CFB boiler, to recovery the energy from the high-temperature flue gas, in order to reduce the fuel consumption. Also, the economizer helps to absorb the air pollutants such as the NOx and sulfur dioxide.
As a new mature high-efficiency and low-pollution clean coal technology, circulating fluidized bed combustion (CFBC) technology has many advantages that other combustion methods do not have. Circulating fluidized bed combustion is low-temperature combustion, so the NOx emission is much lower than that of pulverized coal furnace, only 200ppm.
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.
Ensure that the vent valve on the boiler is open and check there is no pressure in the boiler. Check that the steam stop valve is closed. Check that all the valves for fuel are open, and let the fuel circulate through the system until it comes to the temperature required by the manufacturer recommendation.
A hot water boiler should be thoroughly inspected at first, including the accessory pipeline. Close the drain valve and open the gauge cock to discharge the air in the boiler.
