Export 2 ton steam boiler mobile skid mounted assembly boiler WNS2-1.25-YQ

The design of this product complies with the regulations of TSG G0001-2012 "Boiler Technical Supervision Regulations", TSG G0002-2010 "Boiler Energy Conservation 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 WNS2-1.25-Y (Q), which is a horizontal internal combustion oil (gas) fast installed boiler with a wet back structure. The waveform furnace liner and combustion chamber have one return, the second return is made of threaded smoke tubes, and the third return is made of smooth tubes. An energy-saving device is installed on the upper part of the boiler. The boiler is equipped with fully automatic control and 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 operation of the boiler.

The fuel for this product is light oil or natural gas; The fuel is ejected from the burner, ignited by an electronic ignition rod, and burned at a slightly positive pressure inside the furnace. The high-temperature flue gas after combustion enters the second return flue pipe through a 180 ° turn in the combustion chamber, enters the third return flue pipe through a 180 ° turn in the front flue box, and enters the energy-saving device through a 180 ° turn in the rear flue box for heat exchange before being discharged into the atmosphere through a chimney.

2、 Introduction to the operating conditions of a 2-ton boiler

The operating parameters of this boiler under rated load are: feed water temperature is 20 ℃, pressure is 1.25 MPa, and 2 tons 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 94.9%, the exhaust temperature is 78.3 ℃, and the light oil consumption is 133.4 kg/h. When using natural gas as fuel, the calculated thermal efficiency is 94.5%, the exhaust temperature is 80.4 ℃, and the natural gas consumption is 161.9NM^three/H.

Introduction to the Product Structure of Gas Boilers

The boiler consists of a pressurized body, a base, packaging and insulation, a turning flue, a platform ladder, instrument valves and accessories, a front smoke box, a two-stage condenser, and an 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 seven hundred and two × 12 cylinder and φ one thousand and seven hundred × Formed by welding the front and rear tube plates of 14; The first return is a waveform furnace, which consists of two sections φ seven hundred × 10 waveform furnace liner assembly welding; The corrugated furnace liner structure not only increases the heat transfer area, but also meets the Free expansion of the furnace liner after being heated; The combustion chamber is composed of φ one thousand and one hundred × 12 Inner front and inner rear tube plates and φ one thousand and ninety-eight × 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. 2、 92 pieces for each of the three return trips φ fifty-one × 3 threaded smoke pipes; Threaded smoke pipes can 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 100 energy-saving devices used φ thirty-two × Composed of 3 spiral finned tubes, thereby increasing the heating surface and reducing the exhaust temperature of the boiler.

The front smoke box adopts an integral large door opening structure, while the rear smoke box adopts a split type smoke box door. This form has good integrity, aesthetics, and elegance, and is easy to open during maintenance, with good sealing performance; The boiler adopts Aluminium silicate fiberboard as the thermal insulation material, which has good thermal insulation performance, light weight, 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.
