Overview

1. The steam generator adopts a three pass water-cooled tube shell structure without traditional inner tank design, which has a longer service life and lower maintenance costs compared to ordinary fire tube furnace structures.

Product Details

The ZFQ type fuel and gas non inspection steam generator has a small volume and is easy to install. The entire machine has been installed and debugged before leaving the factory, without the need for inspection, stoker personnel, or annual inspection. It can be used after connecting the power supply and steam pipeline. The steam generator produces steam quickly, with good steam quality, good steam dryness, low water quality requirements, and one click start to adjust the working status according to the load. It has good energy-saving effect and low nitrogen emissions that meet urban environmental protection requirements.
Technical advantages:

2. Set up a front-end preheater and a built-in dedicated energy-saving device, with advanced energy-saving devices for external water replenishment before entering the furnace steam pipe group, fully utilizing the waste heat of the flue gas and significantly increasing the production speed.

3. Equipped with a microcomputer large screen LCD control system, it has fully automatic load adjustment function and perfect abnormal protection locking function. With one click start operation, the generator will enter fully automatic operation by simply pressing the start button. At the same time, the working status of the generator and burner will be continuously monitored, ensuring safety and stability without the need for professional stokers.

4. The steam generator is equipped with original burners or low nitrogen burners, original pressure controllers, safety valves, and multiple protections such as overpressure, low water level, and overheating protection to ensure steam quality and safe use.

5. The steam volume and steam saturation have been rigorously tested to meet industry standards.

Exemption from annual inspection basis: According to Article 1.4.4 of TSG G0001-2012 "Boiler Safety Technical Supervision Regulations" issued by the General Administration of Quality Supervision, Inspection and Quarantine of the People's Republic of China, the scope of D-class boilers is P ≤ 0.8Mpa, and 30L ≤ V ≤ 50L. The water capacity of steam generators, 200kg, 300kg, 500kg, 700kg, and 1000kg fuel (gas) evaporators are all less than 50L, and the rated pressure is 0.7Mpa, which belongs to the production specifications of D-class boilers. According to Article 13.4 of the regulations, products that meet the production scope of D-class boilers do not require independent boiler rooms, installation notices, and installation supervision inspections.
