Advanced Space Heating

>Condensing Furnaces have a waste water discharge ()

>Optional humidifiers () have a need for a fresh (ideally purified) water supply

─ Avoid mineral deposits that reduce reliability and life while increasing maintenance costs

>Two birds with one stone?

66

Advanced Humidifier & Heat Recovery Current GTI SMP Project

>Integrated heat recovery and humidifier for home furnaces

>Captures waste heat and (pure) water from natural gas flue gas combustion

> No external water supply

>Energy savings: 95%+ efficiency

>Greater indoor comfort & savings

>Improved humidifier reliability without bacteria & deposit and dust issues

77

GTI High Efficiency Gas Packaged Air Conditioner (PAC) Project

>Condensing Furnace Specification dealing with

─ Technical issues of secondary heat exchanger & condensate

─ Economic issues of first cost and net operating cost savings

>Prototype Field Test over the 2010-2011 winter

88

Natural Gas Cooling

> Larger absorption or engine-driven chillers provide energy savings in high electric markets

─ Offset peak summer electric demand – potential customer and utility savings

> Smaller options─ Small absorption units (e.g., Robur)

─ Engine-driven heat pumps…build on Japanese products

> Integration with solar thermal and waste heat recovery/CHP

HOT Water ProjectTechnical Objective

> Hybrid Optimized Tankless

(HOT) Water Heater

> Develop prototype and test a

hybrid water heater with best

features of tankless and tank-

type water heater

> Optimize performance,

efficiency, and cost

> Advanced control strategies

and thermal management

Low-Power Gas ValveNew SMP Project

> Industry Need: Deal with the pilot light in a responsible way that does not over burden customers before it is dealt with by others

>Value to the Industry

>Objective: Develop a safe and reliable low power gas valve that can run battery-operated over the 10-year life of a water heater

Non-Powered Powered

Pilot light consumes up to 17% of the total annual energy of a non-powered gas water heater, eliminating the pilot light could provide significant energy savings

Smart Grid

> Electric vs. Natural Gas vs. Energy Grid?─ How should we use natural gas in

a carbon-constrained future?─ Who will manage energy?

> Customers?> Utilities?> Google?

> What value can be created with Smart Grid systems?─ For gas customers─ Energy savings?─ CO2 reductions?

─ 15% carbon emission reduction─ Ultra low NOx (< 9 ppm)

─ Target: < 2 year payback─ Multiple field tests underway

1414

Transport Membrane Condenser (TMC)

> Simultaneously captures waste heat and pure water from combustion products

─ Tubes with nano-porous membrane that selectively removes water by low-pressure-drop capillary condensation

> Applicable to many combustion uses─ Industrial and commercial boilers and steam power

plants

─ Industrial drying & humidification processes

─ Home furnace and humidification

> Recently licensed to Cannon Boiler Works

1515

Submerged Combustion Melter

> Developing revolutionary melter for producing industrial materials

─ Various glass products, sodium silicate, waste material recycling (waste fiberglass, electric arc furnace dust vitrification), etc.

> Unique submerged combustion process yields major improvement in capital cost, productivity, flexibility, footprint, efficiency

> Working with variety of industrial partners

> Multiple licensees

1616

FlexCHP Power & Steam Package
