Safety accessories of the thermal oil heater include safety valves and bursting discs, stop valves, pressure gauges, etc.
The basic configuration of low nitrogen thermal oil heater system includes the following main parts:
1. Combustion system: including furnace, burner, ignition device, etc.
2. Oil circulation system: circulating oil pump, oil injection pump, storage tank, expansion tank, etc.
3. Control system: complete with boiler control box.
4. Air-smoke system: refers to the s...
Low pressure and high temperature: the thermal oil heater can obtain higher working temperature at lower operating pressure, and the maximum temperature of liquid phase can reach 400°C.
In recent years, the state has stepped up efforts of prohibiting the traditional coal-fired boilers. Major enterprises keep up with the times and purchase various environmental protection boilers. Gas-fired boiler is currently the most popular environmental protection boiler. However, due to geographical limitations in some areas, natural gas is difficult to obtain, or the cost is too high, some enterprises will choose biomass steam boilers.
Coking and dust accumulation on heating surface. Whether it is slagging and ash deposition on the water wall of the furnace or ash deposition on the superheater, convection tube bundle, economizer and preheater, the measured thermal resistance of flue gas will increase, and the deterioration of heat transfer will worsen the cooling effect of flue gas, resulting in an increase in the temperature of boiler waste gas.
Make-up water rate refers to the proportion of treated water added to the boilers, steam turbine equipment and its thermal systems and participating in the circulation of steam-water systems in the boiler steam volume in the calculation period.
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.
