This presentation shows the solution that Sammo Energy can bring to the glass industry in term of waste heat recovery for energy efficiency

1. Applications to Glass Industry
Sammo Energy Ltd - Q1 2012 1

2. The Issue
The glass industry is a very energy intensive industry. It uses furnaces at very high temperatures
( 1400 ºC) to melt the raw material and prepare the glass.
Two types of furnaces are used:
• The regenerative furnaces that already use the exhaust heat to preheat the entry air and
• The oxyfurnaces that use an oxygen rich air for combustion.
The new regulation on air pollutants will put an additional stress on this industry to maintain the
NOx emission under every time lower levels.
The industry is permanently looking for ways of reducing their energy costs and consumption
and reducing their emissions and carbon footprint.

3. Our business model
Sammo Energy Ltd is proposing to bring a full solution for the issue of the industry.
Sammo Energy proposes to invest on its own resources to bring the solutions to the industry
using the following approach:
• Full solution implementation integrating power generation and batch preheating;
• No investment needed from the industry, Sammo Energy makes all the necessary
investment from its own resources;
• No adversary impact on the production process, the industry benefits only from the upsides;
• Performing monitoring system follow up the benefits and performances of the systems;
• Based on long term power purchase agreement guaranteeing a price of energy lower
than market price. The industry save money from the very first day of operation of the
system;
• Base principle is to share all side benefits like carbon emission reduction incentives, grants,
etc. All those programs are managed by Sammo Energy in full transparence;

6. Our Operational approach
Oxyfuel Furnaces
High temperature air from oxyfuel furnace exhaust can be used to both generate power and pre-
heat the raw materials.
Power generation should be run through an ORC turbine due to its flexibility and unattended
operations. It is one of the best fit for industrial environment.
The waste heat recovery must be performed as close as possible of the exit of the furnace to avoid
any heat loss and transportation of high temperature gas over distance.
An integrated waste heat system will be designed to make the best use of the heat and preheat the
raw material as close as practicable to the furnace entry in order to avoid losses. It is designed to
take into consideration the space available around the furnace.
Raw material feeding will be adapted to avoid generation of dust cloud at introduction of raw
material.

7. Our operational Approach
Regenerative Furnaces
Regenerative furnaces already capture a large part of the heat of the exhaust in the reversal damper.
Usable exhaust waste heat flow is often below 550ºC.
The same principles could be used, except that, due to lower energy available, a choice has to be
made to give priority either to power generation or to batch preheating.
The transformation of regenerative furnaces into oxyfuel furnace while at the same time installing our
systems allows to reduce the cost of rebuilding the furnace, reduce the emissions of NOx, reduce the
carbon footprint, reduce the cost of operating and make the furnace more energy efficient
