Pellets Boiler - CS Marina Burner

Operating principles

The burning material, which is stored in a silo, is automatically fed into the burner through a duct operated by a conveyor run by an electric engine.
The flame that develops licks the combustion chamber’s surface, heats up the water contained in a cofferdam (gap), which is specifically designed to function to the required power, and travels around the system. The fumes, on the other hand, travel through the so-called 3 rounds fume path, exiting through the hood and the chimney.

The burner

The burner is built with modular cast iron supported by a pipe, also made of cast iron and it can be described as the heart of the boiler. It has a cylindrical shape and it houses the fuel coming through the fuel duct. The fuel burns at its highest capacity when it reaches the combustible air outlets.

Heat exchanger

The heat exchanger plays a fundamental role in heat production. It is built in Mannessiman tubes 60.3 mm in diameter and 3.25 mm thick and is entirely submerged in water.
The fumes, true holders of residual heat in the combustion process, pass through a mandatory path, the so-called “3 round fume” along which they cool down and release heat.
All this guarantees high heat yield and low emissions of carbon monoxide in the atmosphere.
Due to its particular shape, the tube system is easily cleaned and serviced using the steel brush provided to remove combustion residue.
 

Loading fuel

Fuel is stored in the feed hopper placed next to the boiler. From the Hopper it is sent to the burner through a conveyor activated by a geared electric motor. The feed conduit is stepped so as to prevent stored fuel catching fire in the event of a return of flame, caused for instance by a momentary loss of electric energy.
 

Heat loss

In order to minimise heat loss, a thick layer of mineral wool is used to isolate the boiler’s body. Heat conservation is practically guaranteed by the use of thick layers of fireproof material to insulate the doors. These are then hermetically sealed using glass braid sealing strips.
A layer of epoxy powder paint completes the simple, yet efficient design of CTP pellet burner, making it a highly technologically advanced heat source, based on classic criteria of heat production.
 

Hot water production

As an option extras we can provide this removable finned copper coil. This is an indispensable accessory to the boiler. In fact, when completely immersed in thermo vector fluid, it provides constant running hot water.
 

Materials  - Inter-ties

This is a one-piece structure with plates of variable sizes from 4 to 6 mm. It is outfitted with a cofferdam, which surrounds the entire surface of the chamber containing the water before it enters the plant.  The lot is covered with varnished plates coated with epoxy powder that hardens when heated, making the design particularly attractive.
 

Control Panel

The electronic control panel provided is equipped with a general switch that powers the system and also with a control logic through which it is possible to manage both the fuel and the combustive air influx.
At the same time it is possible to check important data such as the fumes’ and the boiler’s temperatures.
The control centre works in 4 stages:

  1. Ignition
  2. Normal operation
  3. Modulation
  4. Maintenance

The latter is surely the most important in that it allows the customer, once the desired temperature has been reached, to save fuel, since the system feeds the minimum amount of fuel needed to keep the chosen temperature.
It is also equipped with a menu easily accessible to the customer and a menu for the technical staff for any eventual adjustments to anti-frost and automatic switch off systems in case of breakdown.
The control panel can be further accessorised by adding a remote control timer. This would enable the customer to maximise the functionality of this technologically advanced control panel.
 

Fuel

The use of pellets is becoming more popular every day. Pellets are small cylinders of compressed wood chippings and shavings, they measure about 6-8 mm in diameter and are approx 10-20 mm long. It is sold in convenient bags of 20/25 kg and can be stored in special containers.
Pellets is an economic fuel and it yields a good heat output.
Other combustible materials that can be used are almond and nuts shells, pine kernels and – in fact – any crushable material.
 

Maintenance

Thanks to the high temperatures reached in the boiler, the build up of residue is practically zero, which means that a weekly cleaning of the tube system and of the hood will guarantee the system’s correct operation.
It is recommended that a general service be carried out at the end of every season.
 

Installation

In line with existing legislation on heat generators using solid combustibles, this requires an open jar/pot/can system according to the following schemes:

The system is to be completed with an optical acoustic alarm.

N.B. this scheme is for indication purposes only: the project manager and the installation manager will have to ensure that all technical safety norms are respected
