IBD System
IHI Boilers Development System

IHI proudly brings the "IBD System", which provides even more effective use of multiple installation of small, high-efficiency once through boiler system that are manufactured using advanced technologies.

This system helps with the rationalization, energy saving, labor saving, and automation of customers' steam system.

-  Features
   A system which makes it possible to simultaneously monitor and automatically prepare
   daily/monthly/yearly reports using a personal computer.
   Featuring an abundance of function from the viewpoint of the person in charge of control.

• Enhanced report preparation function
• Practical assessment of system information
• Strong support of warning alarm response
• Standardly equipped with UPS (uninterrupted power supply) for PCs

-  Parameter setting function
-  Monitoring function
-  Daily/monthly/yearly report function
-  Operation help function (alarm guidance display)
-  Data backup function using an external HDD

For efficient multiple installation boiler

-  IHI's patented new method                    
-  Also support Blue-i SYSTEM
-  Constant pressure control system (patented)
-  Controls up to 32 unit
   Control even possible with a mix of three stage combustion and four stage combustion boilers.
-  Arbitrary operation sequence can be set
   Operation sequence and status (base boiler, standby boiler, etc.)
-  Equipped with a cyclic function
   Equalization of the stop/start count of each boiler
-  Forced low combustion function
   Forces low combustion of boilers which have stopped for a certain period of time in order to speed up steaming and for boiler tube protection purposes, thus maintaining a state close to a hot condition.
-  Mid-purge backup function
   Until the boiler receives a start signal and ignites, the boiler immediately upstream in the sequence which is in a low combustion state switches over to steam pressure during purge.

The steam from each boiler is gathered in one steam header, and then supplied to where it is needed. The multi-boiler control system detects the steam header pressure using a sensor and outputs combustion command signals (combustion stop, low combustion, middle combustion, high combustion) to each boiler so that the pressure of the steam inside the steam header can be maintained at the pre-set value. IHI developed the constant pressure control system to replace the conventional step type multi-boiler control system.
