product presentation:

The pressurized hot water boiler is a pressure vessel, because the pressurized hot water boiler is always in a state of full water, so there is no water level gauge, but a pressure gauge, safety valve and thermometer must be installed. The circulating pump of the high-pressure hot water boiler heating system generally uses the clean water pump, which is the return water of the pumping system project to the boiler, which must overcome the circulation resistance of the system, and maintain a certain pressure of the boiler to ensure that the hot water does not vaporize at high temperature. Pressurized hot water boiler can supply both low temperature water and high temperature hot water

product classification:

Pressurized hot water boilers can be divided into coal pressurized hot water boilers, oil pressurized hot water boilers, gas pressurized hot water boilers and electric heating pressurized hot water boilers according to different fuels. According to the different structure can be divided into vertical pressure hot water boiler and horizontal pressure hot water boiler.

product feature:

1.boiler design, manufacturing, supervision and inspection are strictly in accordance with the "hot water boiler safety Supervision Regulations" to ensure the long-term safe and stable work of the boiler.
2.the boiler body is a shell type full wet back flow three return fireworks tube structure, the flame in the large combustion chamber micro-positive pressure combustion, combustion heat load is low, less harmful NOx emissions. Through many tests and verification of the advanced whole machine test bench, the boiler can get good thermal performance, qualified flue gas emission index and a wide range of burner adaptation under various loads.
3.the boiler before and after the smoke box with special thermal insulation materials, high temperature resistance, low thermal conductivity, anti-cold emergency heat energy ability is good, greatly extend the service life of the smoke box. The lower part of the smoke box is provided with a condensate discharge port to reduce the corrosion of condensed water on the pressurized parts.
4. the boiler device and the pipe mouth layout is reasonable, optimize the water circulation in the pot, effectively prevent scale, but also to improve the water side heat transfer effect. Hand holes and inspection holes are set in the weak link of poor circulation to facilitate regular inspection and maintenance.
5. the boiler adopts the wet-back structure compared with the dry-back boiler, which greatly reduces the temperature of the rear smoke box and solves the phenomenon of frequent maintenance during the operation of the rear smoke box;
6.the boiler is designed with large water volume, the furnace body is not sensitive to load fluctuations, and the load variation range is still suitable for users.
