10 ton steam boiler for chemical production WNS10-1.25-YQ export foreign trade

Product Introduction

The design of this product complies with the provisions of TSG G0001-2012 "Boiler Safety Technical Supervision Regulations" and TSG G0002-2010 "Boiler Energy Conservation Technical Supervision and Management Regulations".

This product model is WNS10-1.25-Y (Q), which is a horizontal internal combustion three way oil (gas) fast installed boiler with a wet back structure. The waveform furnace liner and combustion chamber are the first return, while the second and third return are composed of smoke pipes. The boiler is equipped with complete automatic control devices and safety protection devices to achieve automatic water level control, minimum water level alarm, and boiler shutdown; Automatic control of steam pressure and overpressure alarm; 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 ejected from the burner, ignited by an electronic ignition rod, and burned at a slightly positive pressure in the furnace. The high-temperature flue gas after combustion turns 180 ° from the combustion chamber into the second return, and 180 ° from the front smoke box into the third return. It is then discharged into the atmosphere through the chimney through the energy-saving device through the rear smoke box.

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 10 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 94.2%, the exhaust temperature is 93.9 ℃, and the light oil consumption is 677.3kg/h. When using natural gas as fuel, the calculated thermal efficiency is 94%, the exhaust temperature is 94 ℃, and the natural gas consumption is 818.4NM^three/H.

Product Structure Introduction

The boiler consists of a pressurized body, base, packaging and insulation, platform escalators, instrument valves and accessories, front and rear smoke boxes, energy-saving devices, and electrical control systems.

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 two thousand and four hundred × 16 cylinder and φ two thousand and four hundred × Formed by welding the front and rear tube plates of 18; The first return is the waveform furnace, which consists of two sections φ one thousand and one hundred × 12 waveform furnace liner and two sections φ 800/ φ one thousand and one hundred × Made by welding the conical furnace liner of 16; 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 and seven hundred × 18 years ago φ one thousand and seven hundred × 18 Inner rear tube plate and φ one thousand six hundred and ninety-six × Made by welding the cylinder body of 22; Adopting a wet back form avoids direct erosion of high-temperature flue gas on the rear smoke box, improving the reliability of boiler operation. 219 pieces for the second return journey φ fifty-one × Composed of 3.5 threaded smoke pipes, the third return consists of 154 pieces φ fifty-one × 3.5 smoke pipe composition; Threaded smoke pipes can greatly enhance heat transfer, thereby reducing the heating area, making the boiler structure compact and saving steel.

The front and rear smoke boxes adopt an integral structure, and there is a split type smoke box door on the smoke box. This form has good integrity, aesthetics, and elegance, and is easy to open during maintenance, with good sealing.
