Chain Grate Steam Boiler Definitely Guide FAQ

Boiler selection plays a significant role in optimizing the general effectiveness of your facility. When selecting a chain grate steam boiler, there are several factors you should weigh in, like the heat/fuel source, design, and combustion technology that’ll meet your heating needs.

Here we take a closer look at chain grate steam boilers, from what they are to the different types.

Here we go!

What Is The Chain Grate Steam Boiler?

A chain grate steam boiler is a level three-pass boiler featuring a water-fire tube and multiple threaded smoke tubes inside. The furnace is fortified using light pipe walls that are water-cooled on the right and left sides. The furnace’s front and back arcs are the latest energy-saving technology arches.

Fuel in a chain grate or reciprocating grate boiler normally flows from the coal hopper and gets inside the grate, then to the furnace where it burns. The flame deflects upwards via the rear arch and moves through the combustion compartment on either side of the build headed to the smokebox at the front. From here, it turns back to the tube bundle inside the boiler and goes through the back smoke box.

From here, it accesses the economizer and is tugged by the fan via the flue and to the chimney, where it is released into the atmosphere.

What Type Of Chain Grate Steam Boilers Do You Have?

There are different chain grate steam boilers to choose from; however, today, we focus on coal biomass-fired steam boilers. If you’re looking to trigger the eco-warrior within, here are some chain grate coal biomass-fired steam boilers:

  • The steam boiler chain grates apply a new kind of small-scale grate, adding an unmatched safety ring to stabilize the grate, make it reliable, and promote combustion efficacy.
  • The structure of the twin-wing flue facilitates the smooth entrance of the flue gas to the front smoke box. This way, it maintains the same temperature as the preceding tube sheet, and you can avoid the tube sheet crack instigated by stress.

Reciprocating Chain Grate Stroker

Leaning reciprocating grate


  • A step-design reciprocating chain grate stroker steam boiler garbage incinerator mostly resolves the issue that the present mobile grate cannot properly turn over the garbage, leading to incomplete burning of the garbage.
  • This traveling grate boiler features a slag outlet, pusher, steel frame furnace body, hopper, grate assembly, shut, re-burner booster, secondary combustion compartment, furnace compartment, etc. These coal boiler grates are always horizontal and equipped with a ladder drop. Again, this chain grate steam boiler is split into drying and preheating chambers, combustion chamber, and burning section:
  • The ladder drop is positioned between the combustion zone grate and the dry zone.
  • Numerous detached grate plates link the surface of the grate. The adjoining grate plates overlap down and up, while a specific grate ow is fixed, and the other grate plates row reciprocates.
  • When it comes to the furnace, it is controlled automatically, is highly effective and mechanized, and is easy to use. This chain grate steam boiler is most suitable for enterprises.


  • The horizontal reciprocating grate’s height is a bit low compared to an inclined grate’s, thus efficiently saving the boiler room’s area and reducing the cost of installation and maintenance.
  • In the level reciprocating grate, via this chain grate steam boiler, the coal layer can be covered evenly on the grate, and the interior connection of this coal-fired steam boiler grate is somewhat tight; thus, there is no air leakage. Thanks to the area, the wind speed via the coal boileris pretty uniform, and the cola ash content after burning is reduced considerably.
  • The wave-shaped coal steam on the level reciprocating grate comes in handy, and the surface area stands at 30% to 50% more spacious than the horizontal grate’s surface area. For this reason, the flue gases` flow rate out of the coal steam is slightly slow; thus, the amount of fly ash is less.
  • The combustion proficiency of coal is somewhat high, so the temperature in the furnace is extremely high, and the combustion process is rather efficient, allowing the coal with high coking properties can burn efficiently. Besides, this coal steam boiler can burn cohesive biomass fuels, which significantly boosts the malleability of the grate to fuel.

What Is The Capacity Of Your Chain Grate Steam Boiler?

Typically, the capacity of a chain grate steam boiler is the weight measurement within a given timeframe, normally an hour. The weight measurement can be provided in tons, kgs, or pounds, depending on your situation.

The weight of the steam is sourced from the weight or volume of water converted to steam in the chain grate steam boiler. Seeing as the steam is compressible gas, the steam’s weight could be different owing to pressure. Again, water is a non-compressible liquid; thus, it stays a relatively constant weight.

Since the volume of the water entering the chain grate steam boiler is easier to weigh than steam exiting the boiler, the weight of the water is utilized to measure the chain grate steam boiler’s capacity.

This figure is adjusted for the chain grate steam boiler operating pressure and feed water temperature. However, a plausible chain grate steam boiler should host a minimum capacity of 10 liters of water, and thus its minimum working pressure should stand at 3.4Kgf/cm.

Your Chain Grate Steam Boiler Accepts What Kind Of Fuel?

Chain grate steam boilers can be classified into various categories depending on the fuel used and capacity. Typically, chain grate steam boilers have one drum water and fire tube boiler, and the chain grate is the combustion tool. However, there are those with twin drums that are much more efficient in terms of savings and combustion.

So, in terms of capacity, there are;

  • Double-drum chain grate steam boilers
  • Single drum chain grate steam boilers

When it comes to fuel, chain grate steam boilers typically use three types of fuel; biomass, wood, and coal. So, you have:

The chain grate biomass-fired steam boiler has a wide range of useable biomass fuels like wood pellet waste cloth, bagasse, peanut shell, rice husk, corncob, straw, cotton seeds, and coconut shell.

Plus, to prevent coking and boost combustion efficacy, it adopts an exceptional twin secondary air design to better the conditions of the biomass fuels.

On the other hand, coal-fired steam boilers use coal as the only fuel and are more expensive to operate compared to a biomass-fired chain grate steam boiler. Again, a chain grate coal-fired steam boiler is more costly to use than a wood-fired chain grate steam boiler.

Again, wood-fired chain grate steam boilers use wood, like the hardy outdoor wood boiler grates, ideal for home use. With companies like Jensen wood boiler grates, you can find a reliable chain grate steam boiler for your home.

Well, there you have it, all you need to know about chain grate steam boilers. Hopefully, this piece has helped you choose the most suitable steam boiler to go for.
