Introduction

YLW thermal fluid heater is square coil horizontal chain grate shop-assembled heater, chain grate and heater proper are transferred separately. It adapts chain grate to realize mechanical feeding coal, mechanical venting by blower and induced draft fan, and mechanical discharging by slag machine.

Fuel falls on the grate from coal bucket during operating and burning, high temperature smoke enters furnace by passing combustion arch, after radiation heat exchange, smoke enters convection heating surface for convection heat exchange, then goes to waste heat boiler and air heater, at last enters dust collector then is vented into the atmosphere through chimney by induced draft fan.

Technical advantages

Digitized manufacture

• The laying-off of steel tube adopts CNC 3D laser cutting machine.
• The manufacture of square coil tube adopts CNC three-dimensional tube bending machine, no forced shaping.
• The manufacture of serpentuator adopts serpentuator automatic production line, once-forming.

Full argon arc welding

• Square coil tube and coil tube all adopt argon arc welding technique,which guarantees tubes are 100% qualified.

Long life span

• The optimized radiation heating surface and convective heating surface, the medium flow is more reasonable, without overheat of the carrier and reduce the life;
• Convection section: optimize convection heating surface and adopt effective fix and structural support to make its working life longer.
• Set up effective flue gas partition for convection heating surface and cast partition to make it works longer.

Easy operation

• We have combustion arch patent, which is available for different types of coals, even the anthracite is very easy to burn.
• Flame-proof feeding bucket can avoid the feeding bucket is burnt and coking.
• There is ash cleaning unit, which is easy for maintaining, operating and cleaning.

Less fuel consumption

• Use superior refractory brick to build inside and superior perlite in the middle. Keep the furnace temperature under 50ºC to make the minimization of loss.
• Furnace adopts double close line coil, which makes heating surface sufficient.

FAQ
Q1: Where is your company?
A1: We are located in qingdao which is famous for international business and international sea port, it’s east to delivery boiler to  Southeast Asia, Africa, Middle East, South America, Oceania and Europe.

Q2: What is the Warranty for the boilers?
A2: You will get eighteen months (18) warranty counting from the date of shipment or fourteen (14) months from the date of commissioning, whichever is earlier.

Q3: How about the installation and commissioning?
A3: We’ll specify the service clause for installation and commissioning in details. Generally, our products can be handled by end-users themselves with our documents provided or internet online assistance. However, our service team members also are available for travelling upon request from customers.

 Q4: What’s the production lead time for delivery?
A4: For our standard products, usually it will take about 35-45 days for pressure boilers, and 25-30 days for non-pressure boilers. For non-standard products, time will be different subject to the specifications of pressure, electricity, fuel, capacity, etc.

 Q5: What about your payment term?
A5: Our terms of payment is very flexible, we can discuss and meet your requirement. However, TT is the most welcome term and it has the priority to the price discount.

Q6: What kind of documents will be provided?
A6: Our documents include English instruction manuals, conformity certificate, drawings, manufacturing data, etc. More detailed documents can be provided upon request.

 Q7: What’s your MOQ?
A7: Only 1 set, if you have more than that, you will get a more favorable price.

 Q8: How’s the packaging & shipping
A8: For metal products like boiler body, steam header, tank, etc, they will be packed by stretch film; for accessories, they will be packed in wooden cases or carton boxes. We can handle all shipments including standard container, open top container, flat container, bulk carrier, etc. Because of big dimensions, not all boilers can be loaded into standard containers. For solid  fuel boilers, bigger than 2 ton/hr or 1.4 MW shall be shipped by frame rack (flat) container or bulk carrier.
