Vietnam CFB boiler nozzle

 The company produces:20-160t/h bar and key grate;10-150t/h large scale chain grate;4-80t/h small scale chain grate;1-20t/h light travelling grate stoker;1-100t/h suspende

d reciprocating grate.

  Its characteristics as follows:

  1,bar and key grate:Adopt the strong transom;grate sheets are arranged in the corresponding grooves,the transom is fixed on the chain.The utility model has the advantages of high

stiffness,grate sheet is heated but under no stress,transom and the chain under forces is not heated,grate area is larger,coal leakage and air leakage are rare.It,s more

suitable for grates more than 20t/h.

2.the large scales chain grate without coal leakage:Assembly grates sheets on the chain by splints,overlapping,attaching to each other in fish scale flakes.

Advantages: the chain is not under direct heating,safe and reliable during operation;the grate clearance is small so coal leakage is less;convenient maintenance,cannot 

stop the grate furnace replacement.

3,the small scales chain grate without coal leakage:improved from large scales,have advantages of large scales chain grate without coal leakage and lighter chain grate 

,s advantages,unique in china.

4,light chain grate:use round bar steel to join the initiative and driven grate piece together,to form a large chain.Mesh rotates around the sprocket.

 Advantages:less metal consumption,simple structure,convenient manufacture and installation.

5,reciprocating grate:only do reciprocating motion,has the advantages

 of simple structure,small steel consumption,poking,suitable for low quality coal.

Including small and large flake type 

Flake/squama type chain grate stoker (travelling grate) is a new style fire grate. It features compact, easy to install, not using longitudinal slag remover. During the period of installation, it is not necessary to install under guide rail and take civil engineering. What you need to do is to construct a concrete platform at site only. Not only it has the advantages of big squama type chain fire grate, such as good ventilation property, easy to maintain, etc but also it combines the features of light type chain belt fire grate, such as time saving and save labor when install.

It is whole quick assembling type fire grate with single layer arrangement. When purchase this kind of fire grate, customer needs small investment and low installation expense. Its performance of operation is constant and reliable. It is an ideal selection for small and middle boiler factory and use for boiler to match.

Flake type chain grate stoker has two types:

samll flake type chain fire grate: for 1t/h to 25t/h boiler

big flake type chain fire grate: 10t/h to 65t/h boiler  

Specifications

chain grate stoker is a mechanization equipment applied mostly in steam boiler, hot water boiler and thermal oil boiler 

T type chain grate features:
1. It is matching for 1t-25t/h steam boiler, hot water boiler and thermal oil boiler.
2. The fuel could be soft coal, soft coal and anthracite coal mixed, soft coal and waste wood mixed

The chain grate stoker is a mechanization equipment applied mostly in steam boiler, hot water boiler and thermal oil boiler. It features reasonable structure, reliable performance and convenient installation, etc.

The series products adapt light chain grate stoker and reasonable air distribution device and also strengthen the seal at both sides of chain grate as well as configuration reasonable front and back arch. It features strong suitability in combustion and reasonable air distribution for combustion and quick fire starting. Operation practice provided that combustion heat value is about 18840 kJ/kg. Soft coal with more than 20% of volatile amount and mixed coal can be combusted normally. Moreover it can also combust waste industrial materials such as wood block, sugarcane residual, etc
