Power Engineering




Circulating Fluidized Bed (CFB) boilers.


We offer Circulating Fluidized Bed (CFB) boilers which are characterized by their compatibility with a wide variety of fuels including: low-grade coal, biomass, sludge, waste plastics, and waste tires, etc., whereas conventional boilers for power generation are available only for fossil fuels, such as high-grade coal, oil and gas. As the needs for a fuel shift are rising in response to the current CO2 emission reduction issues and the soaring oil prices, CFB boiler technology is increasingly attracting attention as a viable solution. Additionally, CFB boilers offer benefits such as low pollution, high-efficiency combustion, space saving, and high maintainability. CFB Boiler technology is expected to be at the forefront of next-generation environmentally conscious boilers with capacity - volume of steam: 45 tons/h, electric power output: 10,000 kw. Fuel - wood chips.


Gas engine power generation equipment


E3G Gas Engine


The E3G is a gas combustion engine developed based on the highly reliable and widely adopted PC Diesel Engines. It features the largest bore apparatus and the highest output in the world. This engine achieves high efficiency, low NOx emissions, thereby boasting the highest performance level in the world. A spark plug system is adopted for the world’s largest bore apparatus, therefore fuel oil for ignition is no longer required (unified utility).
The E3G is the first engine of its class in the world to adopt EGR (exhaust gas recirculation) system. This reduces NOx emmissions, and increases efficiency and output by extending the knock limit.

Dual Fuel Engine


In order to deal with the soaring prices of heavy oil and the load on the environment caused by its use there is an increasingly urgent need to change the engine fuel for a cleaner substitute such as gas. However, as part of a plant’s integral BCP strategy it is also crucial to be able to rely on a versatile engine which is compatible with different types of fuel.
We provide Dual Fuel Engines capable of switching their running mode between diesel and gas.  We can also propose the modification of existing diesel engines into dual fuel engines.

Advantages of a Dual Fuel Engine

1) Reduces power generation cost
2) Improves fuel security through the dual fuel system
3) Extends the life-span of existing equipment.
4) Reduces power generation suspension time through the modification of existing equipment.
5) Achieves environmental protection measures (reduces the emission of CO2, SOx, and NOx).

Diesel Power Generation Equipment


We provide diesel engines for vessels and land power generation. These engines are highly reputed in many countries distinguished technology, high economy, and reliability. Compact, lightweight, and high-output medium-speed engines, our diesel engines have the necessary robust engine structure and high durability to meet a wide range of applications such as main engines for vessels and as standalone engines for power generation.

1. Lightweight and compact
2. High reliability backed by long-accumulated experience
3. Extensive service network
We also provide top-range services, allowing our customers to prolong the use of their engines for many years.


Ground-source heat utilization systems

Since the old days, well water has been part of the daily lives of many people as water for living. Cold in summer and warm in winter, well water is said to be comfortable water for people. This property exactly is the action of ground-source heat.
It is said that the use of ground-source heat is helpful in reducing CO2 emissions, which are considered to be the cause of global warming, and is also effective against heat islands as it makes active use of eco-energy stored in the ground and prevent it from being discharged or released into the air.

Our company proposes a ground-source heat utilization system, which makes use of steel pipe piles for construction foundations and thus achieves both the reduction of heat collection costs and the improvement of energy saving with the aid of a high-efficiency heatpump package.
We propse proposes the concept of an optimum energy-saving system with the utilization of ground-source heat at the nucleus according to each customer’s needs.
We conduct a comprehensive feasibility evaluation of construction, structure, and equipment design from the viewpoints of energy saving performance, environmental conservation, and economy.
We support business development, including compliance with the revised Law Concerning the Rational Use of Energy, the Law Concerning the Promotion of the Measures to Cope with Global Warming, and applicable municipal ordinances concerning measures against global warming.
We provides reliable and safe operation based on the collection, organization, and analysis of data through commissioning.
The system contains a program capable of ensuring optimum operation for the building, analyzing measured data, and measuring and evaluating the effects of the introduction of the system. Medium- and long-term energy saving can be expected. For component unit maintenance, it is possible to provide advanced support by collecting operation data and remote monitoring via the energy management system and the communication network.
