Zhongding Boiler is technological innovation-based enterprise in domestic boiler industry, the company own Grade A Boiler manufacturing license, class-I & class -II pressure vessel manufacture license, the main products are CFB boiler, waste heat recovery boiler, coal/biomass boiler, and oil gas boiler. There are different types oil gas boiler, i.e. WNS series wet back boiler, SZS series water tube boiler, and YYQW series thermal oil heater. This article will talk about the auxiliary parts for oil gas boiler, which have high quality to assist the boiler operate smoothly and efficiently. 

1. Burner 

Zhongding Boiler use international famous burner brand: Italy Baltur, Ecoflam, Riello, Unigas ( imported with original packaging) Germany Weishaupt, Finland Oilon. It is general mechanical proportion adjustment, two-stage fire. Generally, 1-5 ton boilers use Baltur or Ecoflam burner (imported with original packaging) --one-stage fire, mechanical proportion adjustment. 6-10 ton boilers usually use Riello or Unigas burner. When the capacity is more than 10 ton, we use Elco or Weishaupt burner----Split type, fully electric proportion adjustment. 

2. Control system 

Zhongding oil gas boiler adopts Siemens PLC（Programmable Logic Control）and Schneider electrical components. It realizes automatic interlock control of water level, pressure, temperature and feed water with high accuracy multiple protection to ensure boiler safe operation. It can realize continuous water supply and frequency water supply constantly and make steam quality to achieve the best effect. If necessary, it can be connected to Ethernet to achieve remote operation. 

3. Economizer 

The economizer can put the smoke temperature below 80 ℃, and improve the heating efficiency of boiler. Zhongding adopts aluminum alloy fin tubes, its heating transfer area is 2-10 times larger than the bare tube, and the heating transfer coefficient is 1-2 times higher than that the bare tube, it has a good heating transfer and mechanical property. The economizer can be set one or two stages. One stage economizer can bear pressure, two stage economizer is a condenser, which is forbidden to use under pressure, It can reduce smoke temperature to the maximum extent. There are also condensation water overflows in front and back of the boiler in order to discharge condensation water out of the boiler. 

4. Steam header 

The steam header could be designed according to customers' requirement, while the drawing size need to be provided by customer. The inlet and outlet shall not be more than half the diameter of steam header. 

5. Water softner 

It is fully automatic and free debugging. The material is glass steel with the characters of high strength, corrosion resistance, acid and alkali resistance and anti-ageing. The material is divided into glass steel and stainless steel; Salt tank is PE material. Zhongding adopts PE material for salt tank body, it has hard texture and it’s easy to move, anti-shock, and no leakage. 

6. Water tank 

There are different materials of water tank: carbon steel, stainless steel and glass steel. Glass steel is incorruptible, rustless, and has a long service life, but it is not sun-proof. If equipped with two-stage economizer, the water tank also needs to be insulated, if not, it is heat loss for whole system. 

There are many other auxiliary pars, such as ID fan, air preheater, water pump, chimney, valves & instruments, Zhongding Boiler could offer customers different choices for the oil gas boiler based on actual demand.
