Modules and components for steam boilers
Equipment for steam boiler plants:
- Feedwater preparation module
- Condensate modules
- Drainage, expansion and cooling water module
- Pump module
- Economizer modules
- Boiler water and feed water analysis module
Feedwater preparation module
- Feedwater preparation module with partial degassing WSM-T
- Feedwater preparation module with complete degassing WSM-VS
- Feedwater preparation module with complete degassing WSM-VR
Design concept:
The feedwater preparation module feeds the steam boiler with treated water and uses desalts and de-salts from the boiler. The module is appropriately sized and optimized for operation. The components are combined into a multifunctional unit of the highest quality, consisting of a hydraulic pipeline, thermal insulation and electrical winding. All functions are computer-assisted by a controller (SPC) with a text display and automatically controlled. By equipping the modules with modems, remote service via telephone or radio link is possible
Scope of application
- The WSM-T module with partial degassing applies to all steam boilers with capacities up to about 8,000 kg/h.
- The module with WSM-V with full degassing applies to all steam boilers with capacities from about 2,000 to 50,000 kg/h with R-type degassing.
Condensate modules CSM
Condensate from the steam absorbers is collected and stored in the condensate module. A condensate pump feeds the condensate into the feedwater degassing system stream according to the level.
High-pressure condensate modules
The condensate from the high-pressure condensate receiver is fed to the high-pressure condensate module, collected in it and fed to the boiler without steam expansion losses. Condensate streams of different pressures are fed to the bulk condensate collector and fed separately to the condensate tank (separated steam and water phase). A feed back pump pumps the condensate without loss of expanded steam directly to the steam boiler. A bleed control maintains a constant water level in the tank. A preheating device and pressure regulator maintain a constant operating pressure. A flow device (optional) conducts the expanded steam to the appropriate absorption units.
Drainage, expansion and cooling module for drain water
The module is used for separate discharge, expansion and cooling of hot water from drains and blowdown lines in single or multi-boiler systems. The temperature of the drain water can be controlled by any LOOS module equipped with SPC. The module is made in four sizes of type BEM 150-1000 for all vertically mounted steam boilers.
PM/PM-P pump module
The module is used to pump and filter feed water from the tank to the boiler
The PM-P pump module is equipped with a three-phase motor with a frequency converter for stepless regulation of the feed water in the pump. In addition, PM-P modules are equipped with a pressure booster pump, so that small quantities are sufficient to prime the pump. To reduce installation time, the modules are supplied partially assembled.
Scope of application:
- The PM-type module is used for all flame-fired boilers.
- PM-P type module is used for all DF steam generators and pressures up to 31 bar
Economizer module ECO-SA
The exhaust gas contains a significant amount of high-temperature heat. A free-standing economizer module (ECO-SA) with a highly efficient compact convection flow uses this heat to heat feed water and increase the efficiency of older steam boilers by up to 5-7%. Flue gas losses are significantly reduced, which reduces pollution.
Scope of application:
Modernization of steam boiler systems with capacities 1250-28.000 kg/h
Water analyzer LWA
The boiler’s LWA water analyzer and feedwater analysis module continuously measure and monitor:
- pH value of the feed water
- O2 level in the feed water
- the trace hardness of the make-up water
- pH value of boiler water
All data is transmitted via the system bus to the LSC LOOS SYSTEM CONTROL system. Along with information on boiler water conductivity and condensate flow conductivity, the LSC system knows all water parameters. Adjustment tasks as needed and control tasks, such as draining metering pumps, can be performed automatically. If a certain limit is exceeded, all parameters are sent to the LSC error memory. The data can be continuously logged. They can also be sent by bus to a master control center or printed by a local printer connected to a defined interface. This means there is no need for manual measurements.
