Introduction

Coal Biomass Fired Thermal Oil Boiler
Structue options: vertical, horizontal.
Combustion stoker options: fixed grate, chain grate, reciprocating grate.
YLW Horizontal Thermal Oil Boiler
Horizontal type thermal oil boiler, automatic fuel feeding, equipped with chain grate/reciprocating grate, high efficiency, environmental-friendly.
Introduction:
Horizontal type thermal oil heater boiler, it has a square coil tube horizontal structure, adopt chain grate mechanical feeding, equipped with a drum and induced draft fan for mechanical ventilation, and equipped with a slag machine to achieve mechanical slag.
How it work:
In thermal oil boiler, thermal oil as heat medium, using the circulating pump to force the liquid thermal oil circulation, then transportingthermal oil though pipes into customers' thermal equipment, do successful heat exchange. Then, thermal oil return back the thermal oil boiler.
Whole System
including thermal oil heater boiler proper, stoker, control cabinet, oil expansion tank, oil storage tank, oil circulating pumps, ID fan, forced fan, economizer, chimney, pipes, valves, gauges, etc.
Energy efficient
1. Close packed disc tube heating surface, heating surface layout adequacy, multi-backhaul heat exchanger.
2. Furnace size match with burning flame, radiation heat transfer efficiency.
3. Positive pressure combustin, so that combustion efficiency is greatly improved.
4. Boiler quality insulation materials and special construction technology, less heat loss, ther exhaust gas temperature is low, the high thermal efficiency of ther boiler.
5. By fully rational surface layout, boiler warming fast start.
Safe and reliable
1. Close-packed disc tube heating surface heating surface arrangement sufficient to reduce the tube sheet heat load, conducting oil safer to use.
2. The boiler operation monitor remote and nearly complete automatic control and monitoring instrumentation, safe, reliable, easy to operate
Easy to install
Boiler full assembled, compact structure, small footprint, is extremely easy to install and flexible, as long as the boiler is located based on.
Application of thermal oil boiler
1. Fuel applicable: Electric, Gas, Lpg, Diesel, Heavy Oil, Coal, Wood, Biomass, Agro Waste.
2. Application industry: Cement industry, Chemical/petrochemical industry, Polymer industry, Textile industry, Leather industry, Oil industry, Glue industry, Food processing industry, Metal industry, Tyre industry, Bitumen & Tar processing industry, Paper mills industry, Wood industry, Soap Detergent industry, Pharmaceutical industry, Paint Varnish industry Packing Packaging industry, Glass industry, Industrial Laundries. etc.
Boiler Features

Multi-loop coil design
Adopts square coil horizontal sturcture, chain grate automatic fuel feeding combustion device, increase heating surface and easier to operate.
Unique warehouse and auto feeding
The big speed bin design could control fuel transmit mass automatically according to the thermal energy, isolate flame and flue to prevent tempering
Countercurrent heat transfer process
After rediation heat transfer by rediation heating surface, it enters the convection heating surface for convection heat transfer.
Economizer & Dust collector device
Reuse waste heat in exhaust gas, energy saving devide (economizer); Remove the dust and ash, protect envrionment and reduce pollutionTechnical Parameter
