Powerchip biomass boiler

Our Powerchip heating systems, with step grate technology, effectively combine maximum economy and minimum emissions. These boilers are perfect for burning a range of fuel types, including wood chips, pellets, grain and miscanthus.

Guntamatic Powerchip

There are many features and benefits of a Guntamatic Powerchip 75kW/100kW biomass boiler.

Highly efficient combustion

The wood chips are gasified on the industrial step grate, where primary air is supplied at an ember bed with a temperature of around 850 °C. The amount of combustion air and fuel charge is regulated by means of a lambda probe, so that the system achieves a level of efficiency of up to 94% with an output of 26%-100%. This ultimately leads to reduced fuel consumption, more heat for your money and a more complete burn. With the aid of secondary air, the generated combustion gases are cleanly and efficiently converted into energy in a large rotating combustion zone. The Powerchip's emissions have been measured as significantly below the maximum emissions set out as a requirement for the RHI.

Cleaning has never been easier

The self-cleaning moving step grate system helps the Powerchip boiler cope with a wide variety and quality of fuel types. An ash screw conveyor transports the ash from the self-cleaning step grate into an especially large moveable ash box. With only 0.5%-1% ash to the volume of fuel, this means you'll only need to empty the ash bin every six to eight weeks.

During the cleaning process, dust from the automatic heat exchanger is also continuously moved into a separate, easy-to-empty container. In addition, the constant motion of the turbulators keeps the heat exchanger tubes free from efficiency-reducing deposits. Moreover, the optional automatic vacuum ash discharge into a 200 litre drum just adds extra convenience to the cleaning process.

Low power consumption

The pioneering discharge system operates with slow turning motors that consume very little power and develop extremely high torque of up to 1200 Nm. In addition, the progressive screw conveyor incline and the optimised trough geometry, ensure the highest operational reliability.

Advanced touch-screen control

Operating Powerchip biomass heating systems is particularly easy thanks to the well thought-out and user friendly touch-screen interface. All settings and scans of system data can be made in just a few steps, and an optional GSM module means you're able to control the Powerchip from your smartphone. The touch-screen interface even makes changing fuel types a simple process.

Industrial step grate technology

Powerchip systems operate with a self-cleaning step grate which is generally only found in larger plants. This enables the ember bed height and boiler output to be adjusted in line with demand and fuel, without risking slag forming inside the boiler. The moving step grate keeps the primary air slots clean, ensures optimum combustion and also that ash is correctly discharged.

High grade components

In order to prevent unpleasant surprises, Powerchip boilers are made exclusively using the highest grade components. The robust version of the agitator motors and screw conveyor discharge, the reliable motors and gear units and the resilient silicone combustion chamber with step grate technology are but a few examples of this.

Fuel fed efficiently

The extremely robust screw conveyor with sprung arm agitator transports the fuel carefully and with the least possible amount of force. Durable and maintenance-free HF gear units and motors provide optimum operational reliability.

Full control

The optional pioneering control app from Guntamatic lets you regulate your heating system at any time and from anywhere. The intuitive user prompts and the touch/swipe controls allow you to call up and adjust temperatures and heating programmes with a smartphone. Furthermore, the app keeps you informed of the current status of your heating system and offers various forms of analysis.
