Teach you how to look at the boiler parameters


What is the gas boiler parameter, the gas boiler parameter is the steam gas boiler, the amount of steam generated by the gas boiler, the working pressure and the steam temperature. For hot water gas boilers, it refers to the heat power, water pressure and return water temperature of the gas boiler. Let's take a look at the parameters of the gas boiler together with Wei Wei.

Evaporation (D), the amount of steam generated per hour during the long-term safe operation of a steam-fired boiler, that is, the amount of evaporation of the gas-fired boiler, expressed in "D", in tons per hour (t/h).

Heat power (heat supply Q), when the hot water gas boiler is operated safely for a long time, the water is effectively charged per hour. That is, the thermal power of the gas boiler is expressed by "Q", the unit is megawatts (MW), and the engineering unit is 104 kcal / hour (104 Kcal / h).

Working pressure, working pressure refers to the maximum allowable pressure of a gas boiler. Working pressure is determined based on design pressure and is usually expressed in MPa.

Temperature and temperature are a physical quantity that indicates the degree of heat and cold of an object. It is also a basic parameter that reflects the thermal state of a substance. Usually used in degrees Celsius is "t °C". The temperature indicated on the nameplate of the gas boiler is the temperature of the medium at the outlet of the gas boiler, also known as the rated temperature. For the steam gas boiler without superheater, the rated temperature refers to the saturated steam temperature under the rated pressure of the gas boiler; for the superheater The steam gas boiler whose rated temperature refers to the steam temperature at the outlet of the superheater; for the hot water gas boiler, the rated temperature refers to the hot water temperature at the outlet of the gas boiler.

In short VFD, is an energy saving device by converting fixed frequency to adjustable frequency to control AC induction motor in variable speed base on the load's changes.

VFD also know as variable speed drive, frequency inverter and adjustable frequency drives. VFD also works as a phase converter to convert single phase input to three phase output in small ratings.

Frequency (or hertz) is directly related to the motor`s speed (RPMs). In other words, the faster the frequency, the faster the RPMs go. If an application does not require an electric motor to run at full speed, the VFD can be used to ramp down the frequency and voltage to meet the requirements of the electric motor`s load. As the application`s motor speed requirements change, the VFD can simply turn up or down the motor speed to meet the speed requirement.

HUAFEI company is expert VFD manufacturer in China, its VFD is mainly used for the machine in coal mine, such as the hoist, belt conveyor, ventilator, water pump etc. Explosion proof type is used under ground with combustible gas and dust. Medium Voltage VFD is mainly used for hoist ventilator or other motor with medium voltage input.
