GENERAL ESTIMATE FOR BOILER FLOWCONTROL
Dear
customer, let us be proud we to present to you by this document, the quite new boiler water-tube '' FlowControl
'' . We let us be assured that it will be be able to surprise by the quality of its construction, its variableness and the performances high which it
get.
We let us ask to you to take a care particular to the analysis of these documents which will show you that we offer a durable product to you, powerful, ecological and easy of maintenance.
This new boiler is available according to two series and in various models covering a range with selection going of 180 Bhp with 1800 Bhp, the pressure of design is of 250 Psig or more according to the request, and gives the use of fuel solid and/or hydrocarbon and/or gaseous. The base ashtray for solid fuel and/or producing residues of solid combustion is optional and by no means necessary at the time of the installation of a boiler performing with gaseous hydrocarbons and/or fuels. The boiler and the base be able be assembled in working site in order limit the modification of the existing infrastructures.
Several fuel types and sources be able be incorporated into this boiler in order make it hybrid and to give to you the full power of negotiation at the time of the purchase of your fuels which, very often, is an important factor
in the profitability and the viability of a company
The internal volume of the combustion chamber and the boiler will also make it possible to deal the residues of productions and the contaminated volumes of air which have to often be to treat independently and represent the imponderable important ones at your costs of cost.
We before let us thank you the interest which will take you in this document in the drawing-up of your future
projects.

DESCRIPTION OF THE BOILER
The boiler '' FlowControl '' makes up of certain number of cell of the water-tube type of a nominal nominal output of 60 BHP or 150 BHP each one. The cells will be manufactured and positioned in order get three passes for the combustion gas and will be connected with nourish feeding and of exit according to the principle of reversed return. The water flow in each cell will be checked per one a valve butterfly modulated according to a signal 4 to 20 My managed by programmable automat. These valves butterfly will be characterised for the development of the power of combustion in order protect the boiler of the thermal shocks and in it to accentuate the general efficiency. Each cell will be swept independently per one a valve with rapid action connected to one nourishes comprising a underlying valve to slow action. The cells will be incorporated into a budget with rigid staff member air-cooled and type with drawer made up of walls in modular panels easily dismountable for cleaning, the checking, the repair or the replacement of cell. In an application with the base for combustion of biomass, the point of passage of the combustion gases between the second and the third pass, of the aspects with rapid opening performed per one a compressed-air cylinder will allow the ash-extraction deposited this low point of the radiator towards the upper part of the furnace bridge of refractory of the
focus.
The radiator will be delivered with controls of required operation, an autonomous automat of management, the principal isolating valves, the relief valves, the valves of underlying drainpipe slow and fast and a pressure
gauge.
The walls in modular panels of the envelope will be made out of steel galvanised gauge 20 welded in which will be placed an insulating plait '' Roxul '' of 2' ', a block isolating 1900
o F of 1 '', a block isolating high temperature 2300 o F of 1 ' '. The sealing of these panels with the rigid staff member will be made by bands of wool of ceramics. A finish and a finish-up paint will be applied to the external part of the panels and the rigid staff
member.

DESCRIPTION OF THE ACCESSORIES
For operation with regular fuels;
The first cell will be of the type '' D '', it will be built according to the same criteria of manufacturing, integrated into the rigid staff member air-cooled and to the budget by modular panels. The walls on side of the cell in '' D '' will be manufactured out of steel in order give the support necessary for the installation of one or two burner, to fix the tubes of cooling
and refractories of plastic high temperature.
One or two burners high performance with the choice of the customer on checking of the owners of flame and the methods of operation to ensure the viability of the
whole.
For operation with fuels producing of the residues of solid combustion;
A base ashtray flattened with rotary tables of extraction for the elimination of residues of combustion. The rotary tables will be air cooled by the heart of the main principle and will maintain permanently a layer of residue for the protection of the plates against the radiant high temperature of combustion. Rakes assembled on scraper chains will ensure the transport of the residue towards a screw conveyor located at the end of the boiler for its clearance. The whole will be complete with limp with gears, the engines with 600 volts, the chain pulleys, the strings, the tensioners and the guards of protection.
For operation with fuels
solid;

The base will be mainly made up of two parts, a first part called '' Combustion chamber '' and a second part called ' ' Anteroom '' having as principal a function to minimise the drive of particle and in it to supplement combustion. The base will be be able to also accept the installation of burners with multiple head using a gaseous fuel or containing
hydrocarbon.
The combustion chamber makes up of a spoon focus of submerged food surrounded by grid out of heat-resistant plastic for the adduction of primary air to combustion. Tubes of secondary air with projection between-crossing will be incorporated into the walls out of refractory of this chamber. The supply pipes in primary air will be incorporated at the bottom of the base and the supply pipes in secondary air will be of each with dimensions base in order allow the installation and the maintenance of the burners multiple head.
The anteroom is a broad trap compelling the combustion gases to a provocative ascending movement the separation of the particles whose combustion is incomplete. The movement of hot gases out of contact with the refractories enables these particles to supplement their combustion and allows also the pre-heating of the biomass conveyed towards the focus under a flag of refractory integrated at the bottom of the base.
The walls of the combustion chamber and the anteroom will make up of a rigid staff member out of steel on which is fixed a block isolating 1900
o F of 1' ', a block isolating high temperature 2300 o F of 1 '' and 8 '' of plastic refractory high temperature having a silica content of 70%. The whole will be maintained in place by bricks
of anchoring to 36' ' DC. A furnace bridge of retention of flame out of plastic refractory will be built in the high part of the combustion chamber, this furnace bridge will be extended until the wall of retention of the anteroom. An injector channel of ash, five (5) traps of access/cleaning and a visor on combustion will be incorporated into the base ashtray. A finish and a finish-up paint will be applied to the external part of the base
ashtray.
