BOILER HEATED HOT WATER SYSTEM
VERSOL can also offer or assist on Water Heating system with Boiler. The complete heating load of the facility is operated with the help of Boilers which may be Gas or oil fired. Boilers can be Hot Water Boiler or Steam Boiler. VERSOL can design and assist on the full System design package including the undertaking of Turnkey project. VERSOL have wide range of boilers under VERSOCALD series which include Real Three Pass Boilers, Reverse Flame Boilers and Condensing Boilers.
Boiler heated water system can use Internal exchangers or External Plate heat exchangers for heat Transfer.
Boilers can be Hot Water Boiler or Steam Boiler.
Hot Water Supply system using Hot Water Boiler with Internal Heat Exchangers.
Figure shows a complete domestic Hot Water system using VERSOCALD Hot Water Boiler with VERSOHEX IM Internal Heat exchangers. Normally there is no need of back up heating sources when boiler forms the Primary heating source. Boiler used is of reverse flame three pass type and fuel can be LPG or Natural gas as per customer requirement. Boilers works in Duty/Standby basis, duty shifting interval can be set as per site conditions.
The combustion produced in furnace generate adequate heat and transfer that heat to the domestic water stored in Calorifier through circulation loop. Circulation loop mainly consists of 1 set Circulation pumps, Expansion Vessel and Three-way valves. Excess or remaining flue gas will be released to atmosphere through flue gas chimney.
Circulation pumps which is working in Duty/Standby basis shall facilitate the heat flow between Boiler and internal heat exchanger in Calorifier. The Duty shifting interval of pumps can be set as per site conditions. Expansion vessel suppresses the excess pressure and temperature that may generate because of thermal expansion of water in closed loop. Three-Way valve is to bypass the heat flow when the Calorifier system is already at desired set temperature. Circulation pumps and three-way valves are controlled by control system.
Calorifier, which is the secondary side has temperature sensors communicating with control system helps to remain water at desired temperature let’s say, 60 deg C.
BOILER HEATED WATER HEATING SYSTEM
VERSOL can also offer or assist on Water Heating system with Boiler. The complete heating load of the facility is operated with the help of Boilers which may be Gas or oil fired. Boilers can be Hot Water Boiler or Steam Boiler. Heat Energy will be circulated between boiler and Heat exchangers in the storage Calorifier with the help of circulation pumps in case of Hot Water Boiler, to maintain the requisite temperature in Calorifier. VERSOL can design and assist on the full System design package including the undertaking of Turnkey project.
In Steam Heated System, , Steam after pressure reduction is to passed through the Storage Calorifier unit Heat Exchanger or External Heat Exchanger. But Steam trapping is carefully designed to ensure efficient system and minimise losses.
VERSOL Hot Water Boilers of range VERSOCALD-HW are designed and manufactured for energy efficient production of Hot Water with up to 95% efficiency. VERSOL Hot Water Boilers are mainly in to two types based on the flame passage which are Reverse flame Boilers (RF Series) and Three Pass Boilers (TP Series)
