Differential pressure transmitter for Boiler, also known as boiler differential pressure sensors, differential pressure devices, etc., what are their highlights and applications in the manufacturing industry? VNTECH GROUP will reveal the details below.

What is an industrial boiler?

Industrial boilers have an extremely robust design and are carefully operated with the purpose to withstand extreme pressures.

Industrial boilers are often used in factories: Chemicals, Animal feed, Food and beverage,….

There are different types of furnaces and inside is a combination of many different devices to monitor, control and operate the boiler safely, save energy costs, efficiently. These include differential pressure measurement equipment in the application of fluidized bed boilers (FBC boilers) and chain grate boilers.

Fluidized bed boilers ( FBC boiler )

Chain grate boiler

The principle of fluidized bed combustion is the process where the fuel is put into the fluidized layer, encounters high temperature and spontaneously ignites. The boiling layer is including: sand, limestone, slag moving up and down due to the wind blowing under the roof. The lower wind blowing in addition to forming a boiling layer also has the function of providing oxygen for the combustion process.

Fuel is supplied to the combustion chamber by a chain grate, and with the lower wind, the fuel will be ignited on the grate, releasing energy to the steam generator beams. Chain grate boiler allows burning of fuels of large size and unequal size, allowing to burn each type of fuel individually or in combination.

With the principle of increasing pressure to generate heat, monitoring pressure and temperature is a basic requirement in boilers.

Requirement of Differential pressure transmitter:

A boiler always has 4 differential pressure monitoring products (differential pressure sensors) which are used sequentially for the following locations:

2 differential pressure sensors control combustion chamber exhaust fan ( Boiler Combustion Air Flow )

2 differential pressure sensors to control the water level for the boiler ( Boiler Drum Level Measurment )

All at above that is necessary for each boiler. VNTECH GROUP has stocked Yokogawa EJA110E differential pressure sensor from Japan to provide fast and best price in the market to boiler manufacturing customers, factories are Using boilers wishing to replace differential pressure products.
