HOSPITAL, INDUSTRIAL AND MUNICIPAL SOLID WASTE

PIROMIXCOMBISYSTEMPIROSTATIC series furnaces are static incinerators operating with controlled combustion (pyrolysis), studied for the disposal of a big range of mixed waste, such as:

– Hospital;
– Industrial;
– Communities in general.

Their particular concept make them easily solve problems related to the disposal of high l.c.v. waste. Among their many advantages it can be mentioned:
• Easy and fast installation and stat-up.
• Easy running.
• Low fuel consumption and operating costs.
• Low and easy maintenance

PIROMIX

PIROMIX series incinerating furnaces are static incinerators studied for thermal destruction of many different materials, mainly hospital waste and industrial wastes in few quantities.
The equipment is then useful for industry, hospitals, campings, hotels and so on.
Easy to use, without problems for installation and operation, they can solve many problems, in accordance with the current legislation on refuse disposal.
The PIROMIX furnace is supplied as “package” unit and requires only easy civil works
PIROMIX series incinerators consist of two chambers: in the primary chamber waste substances are combusted in presence of starved combustion air; in the second chamber, where there is a high operating temperature and sufficient volume to guarantee the fumes staying there enough to complete their thermal purification, the products of gasification are then duly mixed with sufficient air to guarantee complete oxidisation.
In this kind of furnace combustion can then be separated into two clearly defined phases as follows :
• • The first phase takes place inside the primary combustion chamber where the various
• components of the refuse are broken down through volatilization and gasification, thus
• forming a mixture of high heat capacity combustible gases; this initial phase of the process
• has to take place with defect of air so that as far as possible the real combustion will not be
• complete.
• • The second phase consists in the gaseous mixture described above being conveyed to the
• secondary combustion chamber, where, thanks to the steady flow of air in turbulent motion
• caused by one or more auxiliary burners keeping the temperature at around 850° – 900°C,
• the combustible gases produced by distillation of the refuse are fully combusted.

This two-phase process considerably limits pollutant gases from being given off. As the only possible place where solid substances are deposited (in the primary chamber) is working at below stoicheiometric conditions and at low turbulence under operating conditions, only an extremely slight amount of ashes will be emitted with the gases.
The economic and practical advantages to be gained from using the PIROMIX series of furnaces can be summed up as follows :
a) Fewer manual operations: these are limited to charging materials for incineration and removal of waste ashes.
b) Easy operations : once started, the incineration cycle will proceed completely automatically and the furnace should not opened again until after cooling operations, to remove the ashes.
This means that considerably less personnel is needed than with traditional discontinuous furnaces.
c) These furnaces are easy and safe to use, as the various utility controls are fully automatic throughout the entire incineration cycle, so they may even be operated by unskilled personnel.
d) Maintenance has been reduced to the minimum.
The incineration process is fully automatic and the cycle phases can be programmed at the start of the cycle, according to the characteristics of the refuse for disposal.
These phases are as follows :
a) the combustion chamber is completely filled (manually) and the sealed charging lid closed;
b) the programme is switched on and the incineration cycle is commenced by heating up the secondary chamber;
c) once the secondary chamber has reached the operating temperature, the burner in the primary chamber is switched on;
d) complete combustion of the materials to be incinerated will then take place with the burners working in intermittent operation, according to the temperatures inside the furnace and the post-combustion chamber;
e) the burner flame phase stops and the cooling phase starts;
f) once cooling has taken place, the burners blowers will stop;
g) the ashes are removed and the combustion chamber is cleaned after the completion of the cooling of the combustion chamber.

COMBISYSTEM

COMBISYSTEM series incinerating equipments are static pyrolytic incinerators studied for thermal destruction of many different materials, mainly hospital waste and industrial wastes in few quantities.
The equipment is useful for industries, hospitals, campings, hotels, commercial centres, and so on.
Easy to use, without problems for installation and operation, they can solve many problems, in accordance with the current legislation on refuse disposal.

On request, they can be supplied with heat exchanger unit to produce 90°C hot water.
COMBISYSTEM is supplied as “package” unit and will require only easy civil works.
COMBISYSTEM series furnaces consist of two chambers: in the primary chamber waste substances are combusted in the absence of air; in the second chamber, where there is a high operating temperature, and sufficient volume to guarantee the fumes staying there for at least 1 second, the product of gasification are then duly mixed with sufficient air to guarantee complete oxidization.
In this kind of furnace combustion can be separated into two clearly defined phases as follows :
– the first phase takes place inside the primary combustion chamber where the various components of the refuse are broken down through volatilization and gasification, thus forming a mixture of high heat capacity combustible gases; this initial phase of the process has to take place with defect of air so that as far as possible the real combustion will not be complete.
– the second phase consists in the gaseous mixture described above being conveyed to the secondary combustion chamber, where, thanks to the steady flow of air in turbulent motion caused by one auxiliary burner keeping the temperature at around 850° – 900°C (according to local regulation in force), the combustible gases produced by distillation of wastes are fully combusted.
This two-phased process considerably limits pollutant gases from being given off. As the only possible place where solid substances are deposited (in the primary chamber) is working at sub-stoichiometric conditions and at low turbulence under operating conditions, only an extremely slight amount of ashes will be emitted with the gases.
On this incinerator an hydraulically driven automatic loader, can be installed on request.
Moreover, these incinerators may be completed on request with suitable heat recovery systems, to produce hot water for users, to recovery costs.
The economic and practical advantages to be gained from using the COMBISYSTEM series furnaces can be summarized as follows:
a) Clean and hygienic ambient: the primary chamber of the furnace may be charged until completely full, which means it also acts as a deposit for the materials to be incinerated.
b) Fewer manual operations: these are limited to charging materials for incineration and removal of waste ashes.
c) Easy operations: once started, the incineration cycle will proceed completely automatically and the furnace should not opened again until after cooling operations, to remove the ashes.
This means that considerably less personnel is needed than with traditional discontinuous furnaces.
d) These furnaces are easy and safe to use, as the various utility controls are fully automatic throughout the entire incineration cycle, so they may even be operated by unskilled personnel.
e) The immediate environment of the furnaces enjoys improved cleanliness and conditions of hygiene, as combustion requires no control and all openings onto the primary chamber are tightly sealed.
f) Maintenance has been reduced to the minimum, as there are no moving parts inside the combustion chamber; even the nozzles used for blowing air into the primary chamber are easy to inspect from outside the chamber, making cleaning easy, even when the furnace is being used.
The incineration process is fully automatic and the cycle phases can be programmed at the start of the cycle, according to the characteristics of the refuse for disposal.

PIROSTATIC

PIROSTATIC range incinerating furnaces are starved air (so-called pyrolytic), static incinerators, operating according to two-stage controlled combustion process. Because of their design standards and of the careful choice of their constituent materials, they are well able to deal with many and various problems connected with incineration of a wide range of wastes, always in respect to the current legislation on refuse disposal.
Really, the working principle that these units employ, stems from the latest and most advanced incineration technology, and is such as to impose practically no limits whatever on waste calorific value.
This means that the same furnace which comfortably destroys garbage – having a low–to–medium calorific value – will equally well deal with waste having a medium–high calorific value (industrial, clinical, airport and commercial waste above all), much of which has particularly high plastic content.
The two-stage combustion process operated by this so-called pyrolytic method in destroying refuse, not only enhances the efficiency of incineration and simplifies it, but shall not produce any smell and makes for a considerably lower pollution-level in emissions, both gas and solids. The ash volume remaining inside the primary chamber at the end of the cycle is less than 5 % of the initial volume and less than 12% of the initial volume, while the unburnt organic materials in the ash does not exceed the 3% in weight
Moreover, the incinerating plant in the proper sense of word shall be completed with the installation of a dry flue gas treatment equipment, of energy recovery or dissipation devices – according to Customer exigencies – and finally of the requested instrumentation for controlling and monitoring the emissions quality, according to more recent and restrictive European waste incineration directives in force (2000/76/CE directive).
As such, in the great majority of instances, the final solid residue left by the combustion will consist of inert matter, while during the combustion itself any fall out will be even lower than EEC regulations limits.
The main selling points of this series of incinerators are:
• • Low pollutant gas emission
• • Low working costs
• • Speedy and easy installation and start-up
• • Reduced maintenance and easy controls.

All PIROSTATIC equipments are supplied already pre-assembled and require only some easy assembly operations to be carried out on site: installation of postcombustion chamber on the main combustion chamber, erection of the chimney, wiring-up to the control board and fuel connections to the burners.

“Where technically feasible and appropriate, the following systems can be incorporated in the plants presented below if not already installed:
– Mechanised waste loading system
– Energy recovery and wet and dry emission reduction system
– Continuous emission monitoring systems.”
