heat exchanger for hot water from boiler

Forced circulation heat exchanger for hot water from boiler water or steam only in the difference in density between water and steam as the driving force, and requires a certain power to the pump is circulated in the heating duct. Forced circulation oven due to the good water circulation, speed requirements of Sheung Shui is very low; the working pressure is generally more large, high boiler tube material and wall requirements. Forced circulation boiler drum is no longer necessary, you can have the drum, the drum can not; but for a higher pump head requirements, power consumption is greater. When the pump stops running, the pot of water flow is stopped, the need for a reliable way to prevent moisture pot of water hammer.

For example, medium pressure feed water temperature of the heat exchanger for hot water from boiler mostly heated to 172 deg.] C, typically heated to a high pressure furnace 215 ℃. Since the causes of the leakage of high pressure heater, water supply to the boiler feed water through the bypass when the high pressure splitting operation in the heater. After the temperature of the boiler feed water decreases, the fuel portion of the heat to be used to increase the water temperature.

Our company attaches great importance to the quality of wine, winemaking process steam requirements provided very strict, party fast heat exchanger for hot water from boiler provides fully meet our needs, give us a brewery to provide strong support. --customer feedback

8 tph WNS gas-fired steam heat exchanger for hot water from boiler for hospitalThe 54 Central Hospital of the Chinese People's Liberation Army is a tertiary hospital that integrates medical treatment, teaching, and research. With the continuous expansion of the hospital scale, the increase in the number of beds, departments, and trainees, the boiler evaporation capacity of the original boiler room is too small to meet the sterilization and disinfection, sanitary hot water preparation, hospital laundry and so on. In 2012, the 54 Hospital changed its boilers and ordered a 10 tph SZL coal-fired steam boiler for use in the hospital. In recent years, under the increasingly severe atmosphere situation of the whole country and the province, environmental problems have become increasingly prominent. Xinyang has issued the “Implementation Plan for Suppressing Coal-fired Boilers in Xinyang City from 2014 to 2017”. In 2016, the 54 Hospital as a national tertiary general hospital, actively responded to the call for environmental protection, and implemented replacement of coal-fired boilers. Following the last boiler installed in ZOZEN, it was durable, safe in operation, and high in thermal efficiency. This coal-to-gas project still allows ZOZEN boiler to provide 8 tph WNS gas-fired steam boiler.

Heat Exchangers: Copper vs. Stainless Steel - AccuServ

Many HVAC devices use what is known as a heat exchanger to transfer heat from one fluid (e.g., hot water in your water heater) to another (e.g., domestic water running to your tap). The heat exchanger in the most basic terms is a piece of metal that allows the heat from one fluid to pass onto another fluid.

Boiler and Furnace Heat Exchangers

Heating of Domestic Hot Water A properly sized indoor or outdoor boiler can be used to heat the domestic water without the need for an external (stand-alone) gas or electric water heater. Installing a brazed plate heat exchanger allows to separate the non-potable (boiler) water from domestic water and store the later for future use.

Troubleshooting a Gas-Fired Hot Water Boiler

Modern boiler systems for home heating are hydronic systems, in which the boiler heats water for circulation throughout the house.They are closely related to steam boiler systems, but rather than circulating actual steam, hydronic systems have pipes carrying the hot water that radiates heat through either steel radiators or baseboard convectors (sometimes called "fin-tubes").
