ENERGY CONSULTANCY SERVICE
In order to offer a better service to the industry sector, CONTAGAS offers technical advice and training on steam and its use as well as partial or full audits for steam sites. The aim is to provide valid solutions that are a real benefit for companies.
STEAM IN INDUSTRY
Steam is generated by heating boiler water through combustion using fuel-oil, gas, diesel, coal, firewood or a biomass system. Steam is one of the biggest energy sources and it is therefore recommended to make a good use of it for the sake of the industry.
WHAT IS ENERGY CONSULTING?
It is the full study of the current steam and condensate networks on a whole production site.
As far as steam generation systems are concerned, the energy consultancy determines the thermic efficiency of boilers, quantifies the main heat losses, verifies the state of conservation and analyses conditions and operating procedures.
BENEFITS OF AN ENERGY CONSULTANCY
Conducting an energy consultancy has many benefits, among which:
Obtaining energy savings and reducing costs
Improving efficiency in production, obtaining quality steam (saturated)
Improving sustainability of the production process:
Optimizing the production processes
Making improvements to the water treatment system and its recovery
Ensuring the protection of the industrial environment
WHY CARRY OUT A CONSULTANCY ON STEAM NETWORKS
Carrying out an energy consultancy is highly recommendable in case of:
An increase in the number of production lines on a site
Constant steam leaks in valves, vents, pipes, flanges, seals, etc.
Flooded, cold purges
Low performance of steam generators
Water drags and water hammers
Slow heating of the production equipment
Slow start-ups that suppose high costs due to the amount of non-recoverable cold condensates
Old low-performance facilities
WHY CARRY OUT A CONSULTANCY WITH CONTAGAS
Great knowledge of all products in the steam production processes
Extensive experience in steam consultancy in all types of sites
Specialized technicians with over 25 years experience in the sector
Contrasted results resulting in savings ranging from 2% to 70%
WORK METHODOLOGY
To conduct an energy consultancy, we follow a very detailed and exhaustive working procedure in order to make real improvements to the process.
THE STAGES IN A CONSULTANCY ARE:
Study about the treatment for boiler feeding water and steam quality
Boiler performance, efficiency and energy savings: water, electricity, combustion, chemical treatment, reduction in gas emissions
Detection of saturated steam in production
Inspection of components, hand-operated valves and control valves
Inspection of air vents and other equipment
Sizing, mounting and isolation of pipes, inclination and venting points
Optimization and improvement of steam quality
For higher productivity
Recovery of condensates
Important and essential condition to carry out a consultancy: boilers have to be in working condition and production processes operating.
WORK GUIDE
1.
Treatment plant for mains water
Tank for feed water and recovery water to feed the boiler (whole equipment)
Degassing head, if any
Full steam generator/s: combustion, sludge purge and salinity / conductivity
Fumes exhaust
Steam outlet valves and security valves
Purge visual and control levels
Economizer and pre-heaters (if any)
Check valves
Water control
2.
Sizing, air vents and valves
Flash tanks and cooling of boiler purges (if any)
3.
INSPECTION OF STEAM TURBINES (ELECTRICITY GENERATORS), IF ANY
4.
Pipe sizing and reduction, intermediate purges, end purges, air vents, entrained boiler water, dilators, drop separators, check and hand-operated valves
5.
Saturated steam
Use of spacers
Heat exchangers
Different equipment, reactors, heat exchange and production
Flow, pressure and temperature control valves
Sizing steam piping and condensate outlet
6.
Full drains: choose the right trap for each application in the production process
At different working pressures (DP - differential pressure): study for condensate recovery making use of the same return lines
Sizing and inclination of pipes
Recovery pumps
Set of manifolds with mechanic pumps
Dilators, air eliminators
Contaminated condensates (detection systems). All purges have to be used and taken again to the boiler room
7.
Study of each of the previous points (1 to 6) with the improvements to be carried out
We provide information about the energy costs for the company on the audit day and the new energy costs after introducing the recommended changes
Calculation of the savings that the audit will mean for the company
