IHI: World’s first successful co-firing of 70% of liquid ammonia: 2000kW gas turbine
-Stable combustion by applying aircraft engine technology-
IHI:
IHI was the first in the world to succeed in co-firing 70% of liquid ammonia with a 2000kW class gas turbine.
By applying aero engine technology, IHI has developed a combustion technology for liquid ammonia, which is difficult to burn stably.

Liquid ammonia,
Spray directly into the combustor
Mix with natural gas,
Implemented technological development of 2000kW class gas turbine.
For the first time in the world, liquid ammonia with a calorific value ratio of 70% was stably burned.
We also succeeded in “suppressing the amount of NOx generated”.
In addition, some successes were made in “gas turbine operation with 100% liquid ammonia exclusive combustion”.
Stable combustion by direct spraying:

Professor Kobayashi, Tohoku University:
National Institute of Advanced Industrial Science and Technology:
From May 2019, we have been working on “development of technology for stable combustion by spraying liquid ammonia directly onto the combustor”.
“Ammonia normally stored in a liquid state” is used directly without vaporization.
No additional equipment is required, which has the advantage of improving controllability.
2,000kW class gas turbine:
This technology,
Applicable to 2,000kW gas turbine.
Development tests will be conducted from October 2020.
We succeeded in stable combustion at a co-firing rate of 70% and suppression of NOx generation.

IHI Becomes World’s First to Attain 70% Liquid Ammonia Co-Firing Ratio on 2,000-Kilowatt-Class Gas Turbine
March 26, 2021
IHI Corporation
announced today it has raised the liquid ammonia co-firing ratio on a 2,000-kilowatt-class gas turbine to a 70% on a calorific basis.
The technology for this advance
makes it possible to spray liquid ammonia directly into the combustor for mixing with natural gas while constraining nitrogen oxide emissions.
This advance
is the fruit of a project that Japan’s New Energy and Industrial Technology Development Organization (see note 1) commissioned to develop
and commercialize advanced thermal power technologies and conduct advanced research into ammonia co-firing technology for such facilities.
IHI has attained 100% liquid ammonia-fueled firing with this technology on a limited basis.
It aims to overcome operational stability challenges and suppress nitrogen oxide and other harmful components in emissions with a view to commercializing a fully ammonia-fired gas turbine by 2025.
Ammonia offers two vital benefits.
It is free of carbon dioxide emissions and offers considerable potential as an energy source for tomorrow’s zero-carbon power systems.
It is also a common raw material for fertilizers and chemicals, so a solid supply infrastructure is already in place.
Ammonia’s broad adoption as an energy source should accordingly be rapid.
