Use of welding robots Semi-automatic and fully automatic welding robots are used for consistently high quality on highly-stressed welding seams. Optimum design Thanks to an ideal ratio between water content and steam chamber, Bosch boilers are optimised in their design for rapid heating and a high level of steam quality....

6 | Boiler components and controls Boiler components and controls | 7 Modules for steam boilers Our modules for steam boilers allow you to equip your system according to your requirements. They ensure maximum operating safety as well as long service life and a high level of efficiency under the specific operating conditions. Water service module WSM The water service module supplies steam boilers with degassed and chemically conditioned feed water and disposes of the desalting and waste water. ► Feed in and storage of condensate and make-up water ► Thermal partial deaeration of the feed water...

8 | Boiler components and controls Boiler components and controls | 9 Condensate service module CSM Condensate high-pressure plant CHP Condensate from steam consumers is channeled, collected and temporarily stored in the condensate service module. A condensate pump pumps the condensate back into the feed water deaeration plant if the corresponding need for water arises. Unpressurised condensate service modules are usually installed near the consumer. With the condensate high-pressure plant the condensate is kept at pressure and temperature so that expansion steam losses are prevented or significantly...

Boiler components and controls | 11 10 | Boiler components and controls The module comprises the combination of the expansion and heat recovery module EHM with the blow-down, expansion and cooling module BEM. Its purpose is therefore the recovery of the energy contained within the hot water (desalting water/ condensate) and the discharge of waste water taking into account the permitted discharge temperature. The module consists of an expansion tank as well as a waste water and cooling tank. A heat exchanger with associated fittings is integrated for heat recovery. Two cylinders one above the...

12 | Boiler components and controls Boiler components and controls | 13 Flue gas heat exchanger ECO stand-alone A flue gas heat exchanger, also called an economiser, is part of the standard equipment for energy-optimised and environmentally friendly boiler operation. Flue gases contain significant heat potential at high temperature. Economizer modules with their high ly-efficient heat recovery surfaces utilise this heat potential and thus increase the boiler efficiency of new or existing steam boiler systems significantly. The flue gas heat exchanger is installed downstream of the boiler and...

14 | Boiler components and controls Boiler components and controls | 15 Feed water cooling module FWM The flue gas temperature is an important criterion for assessing the efficiency of a steam boiler system. Older and smaller systems have often relatively high flue gas temperatures, which is accompanied by unnecessary high fuel costs. For systems with medium to high operating hours technical solutions for reducing the flue gas losses such as condensing heat exchangers or air preheating systems pays off quickly. However, the feed water cooling module is the most cost-effective alternative for...

Boiler components and controls | 19 18 | Boiler components and controls You can setup the operation of hot water and steam boilers according to your needs with our ready-to-install modules for supplies to the boiler. Our smart control technology enables maximum automation, energy efficiency and reliability. Water treatment module WTM To avoid boiler scale, it is only permissible to operate boiler systems with softened feed water. In the guidelines on water characteristics, the permitted total hardness for different types of boilers and operational modes is limited. For softening water, raw water...
