CalciPulse project (EFRO)

 

 

Pulsed Heat is currently actively involved in an EFRO grant program - with project name 'CalciPulse' - which has started in 2012 and ends in 2016. This project is a cooporation cluster of four leading companies in the region of Gelderland-Overijsel (Netherlands): Industriewater Eerbeek (paper mill effluent treatment plant based in Eerbeek), Rhinetech (machine shop and manufacturer of process equipment based in Arnhem), TU Eindhoven (technical university located in Eindhoven) and Pulsed Heat (location in Eerbeek). The project is targeted at the development of a highly innovative multifuel pulsing burner.

This multifuel pulsating burner is capable of using residual and waste materials in solid or liquid state directly as a fuel or heat source for thermal processes at which only a minimum amount of fossil fuel is required. Consequently the thermal process can hereby be designed in a very simple and compact way with a low residual time, which contributes spectacularly to energy efficiency and emmisions (NOx and CO). By applying the multi-fuel pulsating burner for the thermal processing of the second largest waste stream of a paper mill effluent treatment plant - sludge - a high economical and ecological value can be added to the effluent treatment process. The wet sludge will be processed locally at the plant and dried by the exhaust gases from the pulsating burner as a firststep using the dried sludge as primary fuel, at which approximately 10% of additional biogas is required. The combustion ashes are rich of calcium and will be re-used at the effluent plant as a water softener agent. Transportation of waste materials to central waste processing plants can be avoided.

OUR PITCH

 

7 april 2016

Problem:

Company ExCo (fictitious name) is a medium-sized paper mill with an annual salable production volume of 200.000 tons. The main raw materials are waste paper and raw wood. The 2 most important waste streams are 5.000 tons of bark and 35.000 tons of de-inked sludge. The current disposal costs for de-inked sludge to a central waste processing plant (40 km distance) are relatively high (27 Eur/ton incl. transportation costs); this despite a low positive contribution of bark sales. Furthermore the disposal of the sludge,  which still has a low but interesting caloric value, to a central waste processing plant is not considered sustainable. ExCo is looking for a smart, cost-effective solution with ecological value utilizing the energy and raw material value of the sluge. This could turn around the current disposal costs into financial profits with a financial return or ROI that meets the company’s internal guidelines of maximum 2 years.

 

Context:

Company Pulsed Heat is specialized in the thermal valorization of sludge and similar biomass waste streams. Pulsed Heat’s mission is to provide small-scale , high-efficient and locally applicable technologies, offering our clients the ability to convert their biomass waste streams - on their own site, perfectly matching the required (smaller) scale and economically feasible - into energy and/or valuable products or raw materials. These resources can be used by the paper mill directly for various process purposes or by other close-by companies. As a result transportation costst and related environmental taxations will be reduced considerably. Therefore on-site (local) and smaller scale valorisation is considered as 'real sustainability' by Pulsed Heat. In order to make this re-defined vision possible, new innovative technologies are required, in contrast to the hitherto conventional and only large-scale applicable technologies such as fluidized bed combustion.

 

Solution:

For ExCo, Pulsed Heat developed a system with a patented concept, in which the calorific value of the de-inked sludge together with the bark is used in an optimal way without the use of additional primary fuels. The final products of this process are an ash residue of approximately 11.500 tons/year, to be used for road construction applications or at a local cement industry, and approximately 25.000 ton/year of low-pressure steam (4 baro), which can be used in the paper-drying process directly reducing the mill's gas consumption by approximately 2.000.000 Nm3(gas)/year. The designed installation can be characterized by simplicity and compactness, and is composed of a sludge dryer, a pelletizing unit, a fuel pellet furnace, a steam generator, a flue gas heat recuparator and an exhaust gas treatment installation. The net effect of the project is a turn back of the present annual disposal costs of 900.000 euro/year into a positive income of 300.000 euro/year or in other words an effective saving of 1.200.000 euro/year with an amortization time of the investment of 1,8 years. In this way the originally defined project objectives of ExCo, concerning sustainability and ROI, have been fulfilled.

 

 

PYROLYSIS OF SIEVE RESIDUE OF MUNICIPAL WASTE WATER

30 maart 2016

At the end of March 2016 the first succesful production runs with our flexible and high-efficiency pyrolysator (in cooperation with our partner Nettenergy) have taken place for sieve residue of municipal waste water. Following useful and valuable products have been produced: oil, syngas, charcoal and a sour fraction. This is a promising example of the 'bio based economy' at which biomass is converted into energy streams and/or valuable, locally usable products. 

For further questions or additional information, please feel free to let us know by using the contact form under 'Contact'. We would also like to point out that Pulsed Heat will be present during the STOWA waste water symposium organised at 31 May 2016 in Driebergen. 

SUCCESFUL COMBUSTION OF CALCIUM-RICH FUEL PELLETS IN PELLET FURNACE OF INTERNATIONAL FURNACE MANUFACTURER

 

21 oktober 2015

MID-October 2015 fuel pellets produced from paper industry waste water sludge (also see article about calcium-rich fuel pellets) have been combusted succesfully in an industrial pellet furnace of an international furnace manufacturer.  The furnace temperature was 950 degrees Celsius. This project concerns a mutual development of the international furnace manufacturer and Pulsed Heat targeted at the possibility to process calcium- and/or ash-rich fuel pellets. In a next step the ashes and emissions will be analysed further. This corner stone project offers an enormous potential in the transformation process from waste stream to energy (heat) in combination with a spectacular mass reduction.

We keep you updated!

PRODUCTION OF FIRST CALCIUM-RICH FUEL PELLETS AT INDUSTRIE WATER EERBEEK

 

17 september 2015

Mid-September 2015 Pulsed Heat has achieved stable production of calcium-rich fuel pellets from wet primary/secundary paper sludge with CalciPulse installation consisting of sludge feeding/dosing system, our DryFall dryer and a pelletising press. The fuel pellets have a very good shape retention. As a next step the fuel characteristics will be analysed further. For this purpose a exclusive cooperation has been agreed upon with an international furnace manufacturing company. And last but not least also other fuel pellet opportunities will be looket at from a technical and commercial point of view. 

BASIC ENGINEERING ORDER FOR 10 MTPD PYROFLASH INSTALLATION

 

16 augustus 2015

In close cooperation with the ordering party Pulsed Heat has started the upscaling and modelling of the Pyroflash installation. This step is a logical next phase based on a completed and intensive measuring program at which various biomass streams have been tested in the testing facilities in our Maastricht location. The project is targeted at the continued utilization of all spectacular advantages also at higher capacities and throughput. At the same time the small-scale characteristics, enabling local and on-site applications at individual waste water treatment plants as a prerequisite for economical profitability, has to be maintained.

The RWZI of the future

 

6 juli 2015

Through our subsidiary company Setiva BV, Pulsed Heat pursues to become a business partner with a strong and well-founded contribution to the future requirements for municipal waste water treatment plants. Within the municipal waste water treatment market segment, the core of the present ongoing developments is symbolised by the 'Grondstoffen- en energiefabriek' ("raw materials and energy production plant"), which is supported by the Dutch trade association STOWA. The waste and residual streams of municipal waste water treatment will no longer be downgraded as a 'problem' (i.e. waste stream) but on the contrary considered as an opportunity (resources). Pulsed Heat aims to contribute to this new and promising future actively by means of innovative, highly efficient and profitable (also for small-scale, locally applicable solutions) solutions for the conversion of sludge streams in raw materials, products and energy.

Bio Based Economy

 

30 april 2015

The idea of a 'Biobased Economy (BBE)' implies the transition from an economy dependent on fossil fuels to an economy based on biomass as the dominant resource: from 'fossil based' to 'bio based'. In a bio based economy biomass is used for non-food applications such as raw materials, chemicals, fuel for transportation, electricity and heat. The idea of BBE  gets to the heart of existence of Pulsed Heat. Our solutions can be considered as building blocks for the conversion of biomass into energy streams or in valuable, often locally employable and useful products. Additionally transport movements of (unnecessary) waste materials will be minimised also.
