D type watertube boiler design. D type watertube boilers are designed with a large steam drum at the top, vertically connected to a smaller water drum (or "mud drum") at the bottom, via multiple steam-generating tubes which carry feed water (providing the main heat transfer surfaces for the production of steam).
Biomass boilers are much bigger than conventional boilers, since they will have to have some element of an auto-feed option. In the case of the Baxi Bioflo, it is 1.2m high, while a conventional gas boiler is half the size. The other thing is that gas tends to come from the mains gas supply via a gas pipe.
The industrial watertube boiler (Type D, O, or A) is primarily a steam boiler used for various process applications requiring higher pressures, large quantities of steam, and the possibility of additional heat through integrally mounted superheaters.
Manufacturers use a variety of methods to combust biomass feedstock. The Hurst system uses reciprocating fire grates to move feed stock through the boiler. Designed for use in large industrial settings such as factories, schools and greenhouses, it produces 3,450 to 10,000 pounds of steam per hour at 100 to 400 psi using biomass with a moisture content of 30 to 50 percent.
But with the advent of bent tube design, the boilers were fitted with two drums with a an integral furnace.The boilers are known as D shaped design or D shaped Boilers. Construction of a D type Watertube Boiler. The D type boilers has an arrangement of two drums at the side of the furnace and is surrounded by water tube walls .
Biomass. Biomass boilers generally fall into two categories – those that can only take processed biomass pellets with a small tolerance in size of pellet, and those that can take a range of different fuel types. The latter is more expensive, but more flexible in terms of the fuels that can be used.

Biomass boilers. The biomass is transported from the storage silo up to the boiler and poured into the combustion grate through the feeding system. Usually the feeding system is compounded by one (or more) augers and/or a chain conveyor, designed to guarantee the right supply of fuel to the boiler.
Comparing the cost of biomass boilers with conventional boilers. Biomass boilers start at about £7,000 for a 12kW domestic version, which is sufficient to provide heat and hot water for a 4-bed house. A comparably sized gas boiler will only cost around £2500 to install. A bigger biomass boiler with an auto-feed hopper may cost closer to £12,000.

Biomass boilers can use any type of biomass fuel, in almost any form. One of the most effective is the wood pellet furnace, because wood pellets do not have a lot of moisture included so they burn evenly.
The optimal m ˙ f e e d s t o c k regarding the highest U value was found at 2.5 and 1.8 g/min for biomass types C and D, respectively. These biomass types exhibit the lowest particle sizes; therefore their gasification is more sensitive to the feeding rate. In contrast, the optimum could not be found for the other biomass types due to the limitation of the maximum feeding rate offered by the delivery system.
Boilers of this type can be constructed for capacities from 10,000 PPH up to 60,000 PPH. Design Pressures up to 900 Psig and either saturated or superheated steam boilers.
