Steam and Hot water boilers are widely installed on industrial sites and other large facilities.
Operators of Boiler plant have to comply with strict safety rules and are subject to strict PPC regulations (Pollution, Prevention and Control). Operational efficiency is also increasingly important both in terms of fuel costs and as a major contributor to CO2 emissions.
Ensuring the proper efficient operation of boilers, often at remote sites, is a challenge for many businesses.
A new system from Hexatec will help businesses to operate boiler plant more efficiently. A small remote outstation installed in the boiler house routinely collects data from metering systems and other boiler instrumentation such as flue gas monitoring, TDS controllers, water level and pressure sensors. The system will also record boiler status indicators and local alarm signals. This data is routinely transmitted back to a central computer system where automated checks are made to identify operational problems and, if required, generate e-mail or SMS alerts.
The system records a complete operational history for each boiler installation: run hours, operational temperatures, pressures, blow down times, etc. The system can even store electronic copies of the statutory boiler log books to create a single central record for every installation.
All this information is available from a secure web-site, so facility managers can review the status of all their remote boiler plant from their desk-top PC or the PDA in their pocket.
Web-based input forms allow boiler house staff to add other operational information to the record, to build up a comprehensive operation and maintenance history for each boiler unit.
Any Pollution Control reports required by relevant Environmental Protection Agencies can be produced at a touch of a button.
The fuel and water used by boilers is a major cost to many businesses so a continuous record of efficiency enables mangers to closely monitor operational costs and quickly respond to any changes. Normally efficiency calculations require steam meter readings but where steam meters are unavailable or unreliable, boiler plant performance can be calculated using the ‘Ciber’ energy balance methods developed by STB Energy under the UK Government energy efficiency best practice program.
In addition to fuel savings, demonstrable reductions in CO2 emissions may also provide tax benefits to a business.
Constant monitoring of boiler systems can also reduce unnecessary water losses to reduce water and water treatment costs.
This system is available on new boilers and for retrofitting on existing plant.
Similar systems are available for other major plant items, including Cooling Towers and Chiller Plant.
