Fully Automatic High-Efficiency Energy-Saving Gas Steam Boiler

I. Principle of Boiler Operation:

The WNS series fuel (gas) steam boilers are quick-assembly internal combustion boilers, equipped with high-performance fully automatic burners as the main combustion equipment. They generate high-temperature flames through the automatic ignition function, which then exit the boiler through the upper flue outlet and are discharged into the atmosphere through the chimney. This model boasts high heat exchange efficiency, simple structure, and a long service life.

Section II: Features of the Boiler Body:

1. Crafted from high-quality boiler steel plate, in compliance with the national JB/T10393 standard.

2. Utilizes a pipeline-through structural design, featuring high heat exchange efficiency and long service life.

3. Boilers' weld seams 100% X-ray inspected and accompanied by a certificate of compliance.

4. Utilizes high-quality, efficient thermal insulation materials with minimal heat loss.

Section 3: Features of Boiler Electrical Control System:

Pressure Limiting Automatic Control Device

2. Automatic Safety Valve Discharge Unit

3. Over/under water level, trigger an alarm and immediately stop heating.

4. Overcurrent shutdown and alarm

Principle of Operation for Gas Boilers:

Water inside the boiler drum is continuously heated by the energy released from the combustion of gas fuel in the furnace. As the temperature rises, it produces pressurized steam. Since the boiling point of water increases with pressure, the boiler is sealed, and the expansion of steam is restricted inside, creating pressure to form thermal energy (strictly speaking, the steam in the boiler is formed by water being heated to saturation in the drum at a constant pressure and then vaporizing). As a source of energy, it is widely utilized.

I. Overview

This is a quick-installation horizontal internal combustion boiler with three return passages. It features an offset furnace tube semi-wet-back structure, where high-temperature flue gases sequentially wash over the second and third return passages, and then are exhausted into the atmosphere through the rear smoke chamber and chimney. The boiler is equipped with movable front and rear smoke box lids for easy maintenance. It is fitted with a world-renowned burner and utilizes advanced technologies such as automatic combustion ratio regulation, automatic water regulation, programmable start and stop, and automatic operation. It also boasts high and low water level alarms, and automatic protection features for extremely low water levels, overpressure, and shutdown. This model is characterized by its compact structure, safety, ease of operation, quick installation, low pollution, low noise, and high efficiency, making it widely applicable to industrial steam for enterprises, hotels, office buildings, residential buildings, and other facilities for both industrial steam and heating.

Our company's developed Light Oil Boiler series utilizes a highly advanced, fully automatic burner imported from Italy, which serves as the primary combustion equipment. The burner's combustion program is controlled by a sophisticated controller, enabling all necessary functions for normal boiler combustion. It can automatically initiate protective shutdowns during normal operation, accident conditions, and extreme situations. Equipped with a corresponding level controller and pressure proportional regulator, it ensures accurate high and low water level indication, overpressure indication, and adjustment, guaranteeing water levels fluctuate within the normal range and steam pressure remains within the allowable fluctuation range. It also triggers protective shutdown indicators when the water level is extremely low or overpressure occurs.

II. Key Features

The overall structure is rational, compact, and belongs to the boiler island type, meeting the conditions for quick assembly and factory shipment. The product is composed of three main parts upon leaving the factory: the boiler main unit, chimney, and pipeline system. The main unit and chimney sections have been fully manufactured within the factory, with the pipeline valves and instruments for the main unit already pre-installed. Upon arrival at the site, simply assemble the main unit and chimney. Once the gas, power, and water pipelines are connected on-site, the equipment can be tested. This significantly reduces the installation period while ensuring product quality.

2. Advanced design performance. The boiler's main unit features an integrated structure, with the burner mounted on the front smoke box cover, and the main body primarily arranged with heating surfaces and combustion chambers. It boasts a reasonable and compact structure, low steel consumption, an inclined wave furnace drum, and insulation using a new type of lightweight thermal insulation material. The outer packaging is made of colored thin plates, with a rectangular shape, making the boiler's performance, weight, structural dimensions, and appearance distinctly more advanced and aesthetically pleasing compared to domestic products of the same capacity. The boiler's water supply equipment is configured on the boiler's right-hand base, making it an integral part of the main unit without the need for an additional foundation.

3. The water cycle is simple, the structure of the pressurized components is reasonable, and it can operate safely while ensuring water quality.

4. Complete auxiliary machine set, with advanced comprehensive technical performance.

A gas thermal oil heater is a new type of special boiler with low pressure and high-temperature operating characteristics, capable of heating temperatures up to 340°C in the liquid phase or 400°C in the vapor phase. Organic thermal fluid heating can be used in various production scenarios where a uniform and stable heating is required, and direct flame heating is not permitted, within the temperature range of 150°C to 380°C. The gas thermal oil heater, fueled by gas and using thermal oil as the medium, employs a thermal oil circulation pump to force the medium into a liquid phase circulation, transferring heat to the heat-using equipment and then returning it to the heater for reheating. This allows for high operating temperatures at low pressure and offers high-precision control over the medium's operation. The system has a high thermal utilization rate, and due to its modular installation, it is easy to operate and maintain, making it an ideal, safe, efficient, and energy-saving heating equipment. After the fuel oil (gas) is ignited by the burner, the high-temperature flame enters the inner coil to form a radiant heating surface. After rotating 180° forward from the rear of the inner coil, it enters the annular space between the inner and outer tubes to form a convective heating surface. Then, it enters the second annular space above the middle and outer coils, and finally, it is discharged into the atmosphere through the chimney at the rear of the second annular space.
