Environmental policy The new driver for modern power plant solutions




Emission facts

The emission issue will become more and more important in the future.

In local areas, regulations will be even stricter than they are today.

The main driver for sophisticated MAN Diesel two-stroke environmental technology is the market dominance of MAN´s two-stroke engines in the marine business.

Our two and four-stroke power plant solutions fulfill high standards of international regulations like World Bank and IFC.


Emission facts

Emissions from diesel and heavy fuel oil engines

NOx (Nitrogen Oxides): Function of peak combustion temperatures and oxygen concentration.Reduction: Primary or secondary methods

SOx (Sulphur Oxides): Function of fuel oil sulphur content.Reduction: The most effective means is to lower the sulphur content in the fuel.

CO2 (Carbon dioxide): Function of the thermal effienecy of the complete generating process.

Particulate emissions: A result of:

Ash content in fuel/cylinder and lube oil.Partly burned lube oil dosage.


Environmental policy and regulations

are the main driver for

modern power plant solutions

Economics in power generation

Comparison of pricing in power generation for

2-stroke and 4-stroke


Comparison two stroke vs. four stroke

Investors view Driver for a two stroke Solution

Two stroke Engine with a higher thermal efficiency. (Net Heat Rate)

Two stroke has a lower specific Fuel Oil consumption than four stroke.

Two stroke with longer Time between overhaul (TBO) in service.

Two stroke engine with lower mean piston velocity (MPV) as indicator for lower maintenance costs.

Two stroke is very flexible in fuel share.

Fuel Oil90%

Maintenance6%

Lube Oil4%

Typical Cost Distribution for running costs in Electricity Generation

The equity pay back time for a two stroke solution is under ceteris paribus nearly the same with 4,5 years under a

NPV Analysis. Reasons are the higher thermal efficiency, lower fuel and spare part consumption

MAN Diesel SETwo-stroke engine bio fuel application




Customer: PBB GmbH, cogeneration IPPC (Independent Power Producer Company) based in Oldenburg,

Scope of delivery: Turnkey CHP (Combined Heat and Power) plant to a site in the city of Brake, near Bremen, Germany.

Engine: MAN B&W 7L35MC-S engine, supplying 4.2 MWel to the national grid and 3.6 MWth to a palm-oil refinery situated nearby. The engine is a two stroke, low-speed, crosshead uniflow diesel engine.

Fuel: Crude palm oil with a Total Acid Number (TAN) of up to 15 mg/KOH/g.

Heat rate: 7,400 kJ/kWh at site ambient conditions, corresponding to an efficiency of 49%; plant total efficiency in CHP-mode 87%.

Exhaust gas cleaning: The plant is equipped with an SCR (Selective Catalytic Reduction) catalyst, an oxidation catalyst and an electrostatic precipitator

The emission levels are based on the ISO 8178 measurement method, except for PM values, which are stated according to EPA 17.

NOx level assumes to fuel bound nitrogen. The emissions are recalculated to 15% of O2 at dry exhaust gas at ISO 3046 ambient conditions.

No remarkable SOxemissions.
