Different steam pressures correspond to different steam temperatures.
1. The steam temperature of low-pressure boiler is mostly saturation temperature or not higher than 400℃.
2. The outlet pressure of medium-pressure boiler is 3.8 ~ 5.4 MPa, and the commonly used steam temperature is 450℃.
3. The outlet pressure of sub-high pressure boiler is 5.4 ~ 9.8 MPa, and the common steam temperature is 540℃.
Generally, it is required that the water temperature shall be reduced to 80℃ to drain the water in the boiler. This is because if the water temperature is high, the temperature in the furnace is still very high, and the metal of the furnace wall and heating surface will still accumulate some heat. After the water is released, there is no working medium in the water wall to cool, which makes the wall temperature rise and the temperature rise is uneven, which is not conducive to the safety of the water wall.
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.
As an important heat energy supply equipment, industrial boiler is widely used in food, electronics, paper making, building materials, textiles and chemical industries. According to the medium, industrial boilers can be divided into steam boilers, hot water boilers and thermal oil heaters. In order to solve the problem "How many tons are the rated thermal power of 42 MW of industrial boiler?" First of all, we need to know the basic knowledge of rated thermal power and unit ton.
Power boilers take the chemical energy stored in fuel, convert it to heat energy in the combustion process, and transfer that heat energy to water to produce steam. The transfer of energy from combustion gases to the water and steam is called heat transfer.
In addition to quality, price is also an aspect that most corporate users are very concerned about when they purchase the gas-fired thermal oil heater, so what is the price of a set of high-quality gas-fired thermal oil heater?
1. The types and parameters of thermal oil heater, such as rated thermal power, rated working temperature, etc.
Rated thermal power: heat output per unit time. Thermal oil heaters with different heat output per unit time have different prices.

According to the Wikipedia, fuel oil (also known as heavy oil, marine fuel, bunker, furnace oil, or gasoil) is a fraction obtained from petroleum distillation. It includes distillates - the lighter fractions, and residues - the heavier fractions.
The term fuel oil generally includes any liquid fuel that is burned in a furnace or boiler to generate heat, or used in an engine to generate power.
Woodchips are small to medium-sized pieces of wood formed by cutting or chipping larger pieces of wood such as trees, branches, logging residues, stumps, roots, and wood waste. Woodchips may be used as a biomass solid fuel and are raw material for producing wood pulp.
