condensing gas heating steam heater boiler

Details installed gas condensing heating steam heater boiler combustion system that we need to pay attention when installing a gas boiler combustion system, inviting professional staff in advance of the circuit diagram design, so that when installing the status line installation will not appear unreasonable. Also, pay attention to install some fire-fighting equipment, which can provide protection for our security. Unit ventilation should generally remain the total combustion air amount at the rated load. Combustion process controller provides a separate set of contact start-stop control. May be formulated in a variety of burner start-stop loop cascade control relay 10A is a fuse, relay start-stop control stops the control terminal may be connected to the burner, may directly control the power of the burner. Both constant pressure sensor, water power, fuel, gas pressure set value is detected after the automatic controller opens. Time pressure sensor, water supply, oil, gas, and their detection circuit, alarm and found the problem immediately shutdown flame protection, the controller automatically displays the point of failure, an alarm sounds machine. Installation room oil, gas line gas boiler, boiler room should be strictly in accordance with design, specification, and should refer to the burner. Fuel system pressure test after installation is complete, should be 1.25 times the working pressure (minimum test pressure of not less than 0.4MPa). After the fuel pipe installation system should be flushed with water or steam flushing, flushing should have approved technical measures, the number of washing is not less than the secondary blowing, blow up until the clean medium, should be cleared after the purge debris and dead. After installation of fuel system should be oil circulation system-wide test. The gas should be the shortest route to the burner, the air supply pipe diameter must be larger than the constant value parts of the burner duct.

Boiler efficiency calculation formula

Definition of Boiler Efficiency is “The percentage of the total absorption heating value of outlet steam in the total supply heating value.” In other word, it is a rate how the boiler runs efficiently. The thermal efficiency of our coal-fired boilers is 84~92%, the efficiency of fuel and gas boilers is 96~99%, and the efficiency of biomass boilers is 86-93%. The higher the efficiency of the boiler, the better the heat transfer performance. Increasing boiler thermal efficiency can reduce boiler fuel consumption and reduce boiler operating costs. Increasing the thermal efficiency of the boiler is to increase the effective use of heat and reduce the heat loss of the boiler. The key point is to reduce the heat loss of the boiler exhaust gas and the loss of mechanical incomplete combustion.

Hot water condensing heating steam heater boiler in the school dormitory and classroom building are generally used for central heating, drinking water and bathing water aspects of teachers and students and so on. Shanxi Linxian County high school is an important educational school personnel training for the community. 2017, the school responded positively to national coal to gas and other environmental policies, but also to provide students with a more favorable living and learning environment, the school decided to phase out conventional coal-fired boilers, clean and environmentally friendly replacement for the gas boiler. After getting to know and choose the boiler industry, major companies, determined cooperation with professional production of clean fuel boiler fast boiler-by-side to provide a fast 4.2MW integrated condensing gas hot water boiler (WNS4.2-1.0 / 115 / 70-YQ).

The 1 ton wns series oil and gas condensing heating steam heater boiler adopts a horizontal three-return structure, and the boiler produces fast steam and high thermal efficiency. The boiler adopts a large-area combustion chamber. The combustion chamber is surrounded by a jacketed water jacket. A dense fire tube is arranged on the upper part of the combustion chamber, and an advanced combustion device is arranged. The fuel is fully burned in the combustion chamber, and the high-temperature flue gas enters the dense fire tube to continue to radiate heat. Then gathered in the smoke chamber for further heat release.
