In 2015 our offer is expanded by a new series of SE controllers fitted with a touch, colour 7 HMI panel allowing for control and modification of parameters and current heating set work status. At any moment the user can monitor (depending on controller version) values for oxygen contents in combustion gas (measured by Lambda probe), furnace temperature, combustion gas temperature, boiler temperature, feeder temperature, water level in boiler and sub pressure in combustion chamber. It is possible to control the operation of movable grate, ash removal installation, exhaust fan, primary and secondary air fans and fuel feeding system. Additionally the automated control system is fitted with protection against backfire in feeder conduit. As soon as a failure or an alert 2 occurs, the messages with date and time of recorded commencement and termination appear, and the user can be notified on this via sms or e-mail. The heating set operation can also be monitored and controlled through the website. The controller as well supervises the ash container filling level, and if exceeded, a message is sent. The heating set automatic system can be operated either in automatic or manual mode. For the Redler-equipped plant, it is also possible to set the ash remover operation and idle time, movable grate operation time and frequency (which should be subject to changes according to fuel purity). Moreover, the fuel feeder and the movable grate can be operated either in automatic or manual mode. Preset temp. 80 C Feeder temp. 25 C MADE BY Z.M. HAMECH SP. Z O.O.

WATER BOILER KWH WITH BURNER AZZP FOR BRIQUETTE, CARBIOPELLET, WOODCHIPS, SAWDUST AND TURF NEW! Automated AZZP type burners are suitable for burning the following fuels: pellet, carbiopellet, wood waste in form of sawdust and wood chips with moisture of 40% and granulation of up to 30 mm, and turf with moisture of 40% with use of a special chamotte lining. The burner can cooperate with open heating system boilers. Fuel from the tank is fed onto the movable burner grate by means of a driven worm conveyor. Fuel gasification and burning takes place in the burner located in the boiler s combustion chamber. Then the gases flow from the combustion chamber to exchanger. Process of combustion in the burner should be preceded by ca. an hour long heating up of the chamber. This is possible owing to electric heating elements installed in the burner s chamber ceramic lining. Once the first fuel portion is fed to the furnace, an air fan is turned on at low power, and the lighter located in the body lights up the fuel with hot air. As desired glow temperature is reached, the device enters continuous combustion process. The lighter is turned off, the burner feeds the required fuel portion, fans blow the air for optimal combustion. Once combustion phase is over, the device damps the flame. The burner stops feeding the fuel, and the fans damp the flame, while the furnace gets cleaned from ash remains by the grate motion. The device has a photocell installed so that the entire combustion process can be supervised.

The set comprises boiler KWH-1000 with movable grate and hydraulic piston feeder powered with fuel from container selector KWP through Redler scraper conveyor. The fuel container has a cubicoid shape. On the bottom there is a hydraulic selector housed, which slides forth and back on runners at the bottom of the tank. Thanks to their proper profile, discharger arms transport the fuel towards chute tray, where conveyor is installed. The fuel from the container s chute tray is transferred onto the scraper conveyor which comprises housing in form of a tray with chain falls, driving unit and tensioning mechanism. The fuel is moved on a stationary chute surface with cross-bars arranged at double chain fall to the discharge from where it is delivered into fuel piston feeder chamber. Its main task is to supply the boiler with a portion of fuel while maintaining the adequate combustion parameters applied. The dozer piston is moved by hydraulic cylinder. The dozer features a two-step system for protection against feeder backfire which significantly improves the device operation safety. In the boiler furnace chamber the moisture contained in the fuel gets evaporated and then the fuel is burnt. In order to ensure a uniform fuel distribution in combustion chamber the movable grate has been applied. It provides optimal combustion conditions and enables the material to be burnt completely. The grate is cooled with air which is also considered as the primary air for combustion. Additionally the combustion chamber is fitted with an automatic ash removal system which significantly facilitates the boiler handling, particularly when burning fuels with low calorific value leaving large volumes of ash. Fuel feeding and combustion processes are controlled automatically. The control system is based on a programmable controller, which controls fuel feeding using information received from fuel presence and heating power demand sensors. The controller is fitted with an easy-to-use touch panel.

It is possible to extend controller functions by execution and registration of heat treatment in order to eliminate proliferation of biological hazards (harmful insects, fungi). The controllers allow the drying process to be carried out in the following modes: manual enables setting all parameters for the drying process automatic according to a pre-set program for final wood humidity automatic according to the customer s own program for required wood humidity automatic according to the customer own program based on time setting for particular drying phases semi-automatic with constant values, based on setting the humidity parameters in the chamber and changing these as needed The automatic mode is realised by choosing one of few hundred programs. It must be done by choosing the wood species, thickness, drying rate, final humidity and other additional parameters. The drying process parameters are recorded in the controller memory and can be printed out using the set standard-delivered printer. As an option, the controller can be connected to the computer kiln supervision system KSD1, installed on a PC, enabling the control and operation adjustment of multiple chambers. 2 LARGE-SIZE DRYING KILNS 16 Property External dimensions* Width Depth Height Loading space dimensions Width Depth Height** Heat power consumption (average) kw Electric power consumption kw Single sawn timber load in bundles width 1,200 mm height 1,200 mm Sawn timber thickness 25 mm (25 mm pad) Use of load space Sawn timber thickness 50 mm (25 mm pad) Use of load space * - dimensions based on wall perimeter ** - dimensions to false ceiling

CHAMBER-TYPE KILNS The DQKR-2, DQKF-2 i DQKE-140 kilns are designed to dry hard and soft-wood products up to desired final humidity. The kilns are of segment construction. The segment length is 1480 mm; and the overall kiln length is a multiple of a single segment. The chambers can be joined together of 2 up to 12 segments. The kiln structure consists of aluminium-shape frames. The kiln side, roof, top walls and doors are made of panels filled with polyurethane foam. Each panel is clad with aluminium sheet at both sides. Each segment has a heating and ventilating assembly assigned, which consists of a motor-driven axial fan and a radiator. The air movement in the kiln is cross-wise in relation to the material on a rail-car. Radiators are made of integral bimetallic tubes with heat exchanging area of 1.5 m2 /rm. The heating installation can be powered by steam or hot water, depending on a version. Moreover in the kiln chamber, there is a humidifying system powered independently from the applied heating agent only with water under the pressure of 0.2 MPa. Apart from this, the entire chamber is equipped with chimney assembly and electrical installation. Inside the chamber, there is a rail (gauge 600 mm). Heating system for each kiln chamber is terminated by a distribution assembly with valves, heating agent and humidifying water connections. Each chamber is fitted with measurement and control assembly necessary for the drying process conduction. The measurement assembly is installed in the chamber, and the control equipment is in the control cubicle.

STEAMING KILNS PK Wood steaming kiln of chamber type is set on a foundation. The free-standing skeleton construction is made of aluminium profiles and clad with heat insulating panels of 100 mm in thickness, based on stone wool and aluminium sheet. The filling between profiles and the rest of the structure is made of the special silicone paste resistant to heat and moisture inside the chamber. The kiln door is a sliding type, closed by catches. Its opening and closing is possible by means of the hydraulic system. Wood processing under steaming in steaming chambers means warming up the wet material with saturated steam and keeping it in heated conditions over a specified time period. Beech is a basic wood that is processed under steaming. The outcome is reduction of inner stress of wood, sterilization, flexibility, change in colour, etc. Chamber equipment: steaming installation (steam 0.06 MPa, 113.5 C) humidifying installation (water 0.2 MPa) back outlet chimney roof chimney (optional) control automation system WOOD STEAMING KILN SCHEME Type Wood steaming kilns PK Load space [m] External dimensions [m] Single load 40% Width Depth Height Width Depth Height of full volume [m 3 ] Heat power consumption [kw] PK 30 6 3,8 4 7,17 5,03 5,42 36 290 PK 20 4 3,8 4 5,17 5,03 5,42 24 195 PK 16 5 3,8 3 6,17 5,03 4,42 23 185 HIGH-TEMPERATURE STEAMING KILN PW High-temperature steaming kiln PW is a chamber-type plant designed for thermal processing of hard- and softwood under steam conditions and temperature of up to 200 C to improve some of the physical and chemical properties of wood, and to modify its colour.
