Vertical Type Chain Grate Hot Oil Boiler

Vertical Type Chain Grate Hot Oil Boiler

YGL series coal or biomass thermal oil boiler is a new type heating equipment with the fixed grate as combustion equipment, it is a vertical type boiler with coal or biomass (wood chips, bamboo chips, straw, rice hull, peanut shell, bagasse, mustard stalk, cotton stalk, cotton seeds, coconut shell, corncob, waste cloth, etc.) as fuel, and flue gas as heat source, heat conduction oil (such as L - QB, L - QC, L - QD, etc.) as the heat carrier, through the circulating pump to force heat transfer medium to circulate in liquid phrase, and transfer heat to heat user equipment, then return to the heating furnace for reheating, it is a kind of high temperature, low pressure, energy-saving equipment. Heating temperature can be as high as 340 ℃, and generally under working pressure of 0.8 MPa. Because of working in liquid state, it is safe and reliable.

Rated Capacity:

700~3500 KW

Pressure:

0.8Mpa

Certificate:

ISO 9001, CE, BV, SGS, ASME

Fuel:

Different coal and biomass fuels

Boilers Structure

Vertical Type Chain Grate Hot Oil Boiler

1. Separated design for combustion equipment and upper furnace, according to the different nature of the solid fuel, furnace can be design individually.

2. The structural grates has fixed and moving types, depending on the fuel nature, it can be manual or mechanical feeding.

3. The boiler combustion chamber is composed of vertical large diameter circular tube, large fuel combustion space to ensure complete combustion, achieves high thermal efficiency.

4. Furnace internal and external spiral coil is made of bulls, small diameter steel pipe coil thermal expansion of good performance, low stress, safe and reliable.

5. Three return flue gas structure, medium flows through the inside and outside coils, with uniform velocity, safe and stable operation.

6. Precision control on outlet oil temperature, multiple protection and control are set on medium temperature, pressure and smoke temperature to ensure safe and reliable operation.

Auxiliary equipment

CHAIN GRATE

CHAIN GRATE

The grate could be chain grate or moving grate, it uses small flaker grate, has lowl fuel leakage, and long working life.

CONTROL SYSTEM

CONTROL SYSTEM

We adopt Siemens PLC and Schneider electrical components. can realize automatic interlock control to ensure boiler safe operate.

AIR PREHEATER

AIR PREHEATER

Air preheater could be equipped to extract the heat form the flue gas, make fuel use of heat, increase thermal efficiency.

WATER PUMP

WATER PUMP

We adopts the stainless vertical pump with low noise, stainless impeller and pump body.

Steam header

Steam header

Standard configuration: one inlet, three outlets, equipped with pressure gauge and thermometer. It can be designed according to customers' requirement.

Water softener

Water softener

It is fully automatic and free debugging. We adopts PE material for salt tank body, it has hard texture and it is easy to move, anti-shock, and no leakage.

Quality

Zhongding Boiler pay more attention to the boiler quality from raw material to producing process.

boiler quality
we choose domestic well-known manufacturer who can provide component report of raw material, to ensure the raw material is qualified. After the completion of raw material procurement, there are specialized technicians in our factory to make sampling chemical composition analysis and physical performance analysis, and we can also provide raw materials inspection report.
We adopt numerical control cutting, which has the advantage of high precision, neat cutting surface, nice appearance and high material utilization.
Boiler manufacturing
Boiler production
We adopt submerged arc fully automatic welding. When each welding process is done, the 100% X-ray inspection will be arranged for every welding seam, which can prevent the defective parts from flowing into the next process.
