Features And Benefits - Bosch CHP CE 240 NE Technical Manual

System solution: 4-draught steam boiler with combined heat and power (CHP)
1.3

Features and benefits

A CHP module provides several benefits, besides saving
resources and reducing the environmental impact,
significant revenues can be achieved using the current
produced by the CHP module.
The revenue is composed of credits for created current
and credits for created heat. Here is must be
differentiated whether the current is produced for own
use of whether it is completely fed in the upstream
mains.
Benefits for end-customers/investors/plant users
• Low consumption of primary energy compared to
conventional, separated production of current, steam
and heat
• Is gentle on the environment: Saves CO
resources
• Remuneration for self-produced current in
accordance with corresponding national regulations,
e. g. Germany EEG/KWKG
• Amortisation time/ROI of less than 3 years possible
• Sustainable due to decentral energy generation
• Space-saving, no installation of additional peak load
boilers
• Modular system with all benefits of CHP operation
concerning supply reliability, efficiency and current
cost reduction at simultaneously reduced complexity

Benefits for planners/engineers
• Safe planning
– Boiler and CHP module, all from one source
– Functional system hydraulics and standardised
schematic diagrams
– Complete list of components, defined limits of
delivery
– Integration of higher-level control
(Bosch MEC system)
• System safety
– Tuned and certified safety equipment
– All flue gas temperatures from the Bosch CHP
module are securely attained, also in partial load
and operation
2
– Optimised flue gas sound insulation – smoothed
flue gas pulsation, solutions for use in industry,
mixed and residential areas
– Tuned control with bypass dampers with safety
function
– Matched flue system, optimised to admissible flue
gas back pressure of CHP module with regard to
wear of system, maintenance and contamination
– Matched material pairs in flue gas path
• Excellent price/performance ratio/fast ROI/low TCO
– Meaningful, sustainable calculation of economic
viability
– Overall efficiency of CHP module > 70 % by using
waste heat in steam boiler and limiting the flue gas
temperature downstream of the fourth draught/
economiser and use of MEC system
– By using the MEC system, the runtime of the CHP
module is optimised by tuned control strategy.
