BOILER HOUSE INSTRUMENTATION AND CONTROLS

Boiler House Instrumentation And Controls

Boiler House Instrumentation And Controls

Boilers are used in a broad range of industries such as electric power, pharmaceuticals, chemicals, ceramics, and paper and pulp. Amid the rising energy costs, tightening environmental regulations, and increasing awareness of safety as of late, the needs for high efficiency operation, low emission operation, and safe and stable operation of boilers are growing.

Drum Level Measurement

DRUM LEVEL MEASUREMENT

Overview and Problems

  • Drum level measurement
  • High stability measurement required under large static pressure change

Solution

  • Field proven silicon resonant sensor guarantees long-term stability
  • EJA: 0.1 % of URL 5 years
  • EJX: 0.1 % of URL 10 years
  • Under all conditions (temperature, static and over pressures)

Benefits

  • Long term high stability measurement is realized under actual plant condition

COMBUSTION CONTROL

Overview and Problems

  • Perform safe and stable control at low cost
  • Lower levels of emission output 

Solution

  • Simple programming by Function Block wiring method
  • Cascade primary direct control
    – Stable level control when the boiler is started
  • Cross limit control calculation
    – Air and flow are calculated so that air flow always exceeds fuel flow to prevent incomplete combustion and explosion
  • Feedforward control
    – The mainstream pressure and feed water level are controlled quickly in response to changes in the mainstream flow

Benefits

  • Reduced debugging time
  • Improvement of the reliability of programs
  • Safe and stable control at low cost
Combustion Control

STEAM FLOW MEASUREMENT

Overview and Problems

  • Flow measurement for utility steam
  • Conventional orifice flowmeter requires complicated, high-cost installation and is not accurate

Solution

  • Inline flowmeter
  • Built-in temperature sensor, Tek-Vor 1300C MV
  • Steam mass flow measurement without additional temperature sensor/transmitter and flow computer
  • Accuracy 2 % of reading

Benefits

  • Low installation and operational costs
  • Safety operation to reduce leakage points
  • Save energy by accurate measurement
COMBUSTION CONTROL

Overview and Problems

  • O2control for optimum combustion of large-sized combustion equipment
  • High installation cost for multipoint measurement

Solution

  • Maximum 8 detectors can be connected to one AV550G converter
  • O2measurement of multiple points, individual concentration, and average values

Benefits

  • Accurate control by multipoint measurement
  • Installation cost reduction
Combustion Control o2
Exhaust Gas Analysis
EXHAUST GAS ANALYSIS

Overview and Problems

  • Air pollution control by continuous emissions monitoring
  • High maintenance frequency 

Solution

  • Simultaneous measurement of up to five components, NOx, SO2, CO, CO2, O2
  • Sample conditioning system designed to reduce maintenance
  • No moving parts in the sensor 

Benefits

  • Accurate control by multipoint measurement
  • Installation cost reduction
