WNS1-1.25-YQ 1 ton steam boiler, natural gas steam boiler, 1.25Mpa

1、 Product Introduction

The design of this product complies with the regulations of TSG G0001-2012 "Boiler Safety Technical Supervision Regulations", TSG G0002-2010 "Boiler Energy Saving Technical Supervision and Management Regulations", GB/T16508.1~16508.8-2013 "Shell Boilers", and NB/T47034-2013 "Technical Conditions for Industrial Boilers".

This product model is WNS1-1.25-Y (Q), which is a horizontal internal combustion oil (gas) fast installed boiler with a wet back structure. The corrugated furnace liner and combustion chamber are the first return, while the second and third return are threaded smoke pipes. An energy-saving device is arranged on the upper part of the boiler. The boiler is equipped with complete automatic control devices and safety protection devices, with high and low water level alarm and low water level interlock protection functions; The automatic ignition of the boiler, automatic adjustment of burner firepower, and flameout protection ensure the safe operation of the boiler.

The fuel for this product is light oil or natural gas; The fuel is sprayed out of the burner and ignited by an electronic ignition rod. It burns under slight positive pressure in the furnace chamber. The high-temperature flue gas after combustion enters the second and third return threaded smoke pipes by turning 180 ° from the combustion chamber, and enters the energy-saving device for heat exchange by turning 180 ° from the upper part of the rear smoke box. It is then discharged into the atmosphere through the chimney.

2、 Introduction to Boiler Operating Conditions

This boiler can operate stably under 80% -100% operating conditions. Under 100% rated load, the operating parameters of the boiler are: the feed water temperature is 20 ℃, the pressure is 1.25 MPa, and 1 ton of water vapor with a temperature of 194 ℃ can be generated within 1 hour. When using light diesel as fuel, the calculated thermal efficiency is 94.5%, the exhaust temperature is 88.1 ℃, and the light oil consumption is 67.2 kg/h. When using natural gas as fuel, the calculated thermal efficiency is 94.3%, the exhaust temperature is 87.1 ℃, and the natural gas consumption is 81.1NM^three/H.

3、 Product Structure Introduction

The boiler consists of a pressurized body, base, packaging and insulation, flue, instrument valves and accessories, front and rear smoke boxes, platform ladder, energy-saving device, and electrical control system.

The overall structure of the boiler body adopts a lower furnace liner, with smoke pipes arranged symmetrically on the left and right sides, and the drum is composed of φ one thousand five hundred and four × 10 cylinder and φ one thousand and five hundred × Formed by welding the front and rear tube plates of 14; The first return stroke is the waveform furnace liner, which is composed of φ six hundred × 10 waveform furnace liner composition; The use of a corrugated furnace liner structure not only increases the heat transfer area, but also satisfies the free expansion of the furnace liner after heating; The combustion chamber is composed of φ one thousand × 12 Inner front and inner rear tube plates and φ 12 hours a day 6 days a week × Assembled and welded from the cylinder of 14; Adopting a wet back form avoids direct erosion of high-temperature flue gas on the rear smoke box, improving the reliability of boiler operation. The second and third return trips consist of 63 pieces respectively φ fifty-one × 3 threaded smoke pipes; Threaded smoke pipes can greatly enhance heat transfer, thereby reducing the heating area, making the boiler structure compact and saving steel. Install energy-saving devices on the furnace top, with 60 energy-saving devices used φ thirty-two × Composed of 3 spiral finned tubes, it greatly increases the heating surface and reduces the exhaust temperature of the boiler.

The front and rear smoke boxes adopt an integral double door structure, which has good integrity, aesthetics, and elegance. It is easy to open during maintenance and has good sealing performance; The boiler uses aluminum silicate fiber board as insulation material, which has good insulation performance, light weight, and convenient transportation and installation; The upper part of the boiler is equipped with a manhole device, and the lower part is equipped with an inspection device for easy maintenance and upkeep.
