CWNSLN series condensing indirect atmospheric pressure hot water boiler

Condensing atmospheric pressure hot water boilers use heat medium water for indirect heating, the heat released by fuel combustion is absorbed by the heat medium water, and the heat medium water is pumped to the external heat exchanger for heating The water exchanges heat to supply clean hot water.
Because the boiler body is operated under normal pressure, the heat medium water in the furnace only circulates between the body and the heat exchanger during the whole process of the boiler operation, and there is almost no loss. After the hot water in the furnace is heated, Deoxidation and softening, no corrosion, no scale, and no danger of boiler dry burning, prolonging the service life of the boiler.
A condensing heat exchanger is installed in the tail flue, which absorbs the sensible heat and latent heat in the flue gas, and effectively improves the thermal efficiency of the boiler.
The warm water is indirectly heated through the stainless steel tube heat exchanger, which can provide rust-free clean hot water.
With expansion tank, durable.
In a single boiler, three kinds of heat exchangers for heating, warm water and circulating heating can be set up, and the selected surface is wide and efficient.
During installation, it saves time for on-site installation of exchangers, hot water heaters, primary circulating water pumps, etc., and greatly saves installation space, initial investment costs, operating costs, etc.
Boiler water runs at low temperature, and the corrosion of dissolved oxygen is excluded, and the heating surface of the boiler is not scaled.
Even if it is used in high-rise buildings, you only need to choose a high-lift heat supply pump, and the boiler body is not under pressure, so it runs freely, safely and reliably.

hot water boiler

Hot water boiler: In the design of the air conditioning system, the choice of the cold and heat source has attracted much attention because it is related to the primary investment and operation and management costs. For the cold and heat sources of industrial and civil buildings that use central air-conditioning systems, the author believes that the use of chillers and fuel (gas) hot water boilers is a very good cold and heat source solution. In summer, centrifugal (screw type) chillers are used to provide 7°C~12°C cold water, and in winter, oil (gas) hot water boilers are used to provide 50°C~60°C hot water. At present, there are many fuel (gas) hot water boilers, such as pressure hot water boilers, atmospheric pressure hot water boilers, vacuum hot water boilers, etc. Among them, vacuum hot water boilers are more concerned by users because of their safety.

WNSCQ condensing waste heat recovery steam boiler

The condensing waste heat recovery boiler mainly absorbs the latent heat of vaporization by increasing the condensing heat exchanger, the air preheater and the water vapor in the condensing flue gas, reducing the exhaust gas temperature and reducing the exhaust gas loss. In addition to improving the utilization rate of heat energy, in the process of flue gas condensation, the gas components in the flue gas are absorbed or reacted by the condensed water, so that the content of harmful gases SOX and NOX in the flue gas is reduced, which plays an environmental protection role in purifying the flue gas. The boiler body is cylindrical, and the tail of the flue is equipped with a heat pipe air preheater and a stainless steel fin tube condensing heat exchanger, which fully absorbs the sensible heat of exhaust gas and the latent heat of condensation of steam in the flue gas. set at the same time
