The boiler adopts micro-positive pressure combustion and horizontal arrangement. The front end is fixed, and the furnace is expanded backward after ignition. The furnace is designed to expand upward, and the expansion is free during operation. The pressure element is not subject to any heating stress, and the work is safe and reliable.

CEJW is based on proven design for building complexes, commercial structures, and light industry. This boiler can be connected directly on the high voltage power distribution network.

Upper energy vacuum hot water boiler is divided into ZWNS-Y type fuel oil, ZWNS-Q type gas and ZWNS-D type electric heating vacuum hot water boiler three kinds. Shangneng ZWNS vacuum boiler series all use water boiling at low temperature under low pressure to produce steam, and the working principle of heat transfer through the condensation of soft water to achieve efficient operation of the boiler, so as to achieve the purpose of energy saving. This product can be widely used in various places.

ZWNS Vacuum Boiler with Low NOx (NOx < 30mg/m3) is designed based on the original ZWNS Vacuum Boiler, which has three return. The Low NOx type ZWNS adopting a FGR with four-return heat transfer structure (invention patent No. : ZL 2015 10428578.1). Higher thermal efficiency, lower combustion reaction zone temperature, and finally achieve ultra-low nitrogen emissions (NOx < 30mg/m3).

CEJS High Voltage Electrode Steam Boiler is designed for use on 3 phases, 3 wires distribution to the circuit breaker. Electrode boilers utilize the conductivity and resistive properties of water to carry electric current and generate steam.

WNS horizontal oil-fired gas boiler produced by Zhejiang Shangneng Boiler Co., Ltd. is a shell type internal combustion three-return all-wet back fire tube boiler designed and produced by our company according to domestic and foreign advanced technology and experience, which can both fuel and gas.

The CWNS horizontal oil-fired gas boiler produced by Zhejiang Shangneng Boiler Co., Ltd. is a shell type internal combustion three-return all-wet back fire tube boiler designed and produced by our company according to advanced technology and experience at home and abroad, which can both fuel and gas. The wet-back structure of the offset furnace is adopted, and the high-temperature flue gas successively washes the second and third return flue pipes, and then drains into the atmosphere through the chimney from the rear flue chamber. The boiler is equipped with movable front and rear smokebox covers to facilitate boiler maintenance.
