SEATTLEMarch 22, 2021 /PRNewswire/ — ClearSign Technologies Corporation (Nasdaq: CLIR) (“ClearSign” or the “Company”), an emerging leader in industrial combustion and sensing technologies that improve energy, operational efficiency and safety while dramatically reducing emissions, announced today that the company has completed the government performance testing required for their 2-ton fire tube boiler burner to be sold in the Chinese Market.  The performance testing results have been submitted along with the required documentation for certification in China.  Once the certification is granted, the company can produce market and sell the burners in the Chinese market.  Additionally, the Company signed a non-binding CFA agreement with Jiangsu Shuang Liang Boiler Co. Ltd to provide a next generation ultra-low emission, and high efficiency integrated boiler burner package for the Chinese market.

In line with the company’s commercialization plans for its fire tube boiler burner products in China, the product type testing application was successfully submitted and accepted by the Chinese government burner testing authorities.  Acceptance of ClearSign’s formal application was required before the government agreed to proceed and schedule formal ‘on-site’ commercial burner product testing for safety, performance and to verify that the burner is in compliance with the Chinese regulations.  The formal testing was recently completed by government representatives and the full application was then submitted for review by the Chinese authorities.  The company hopes to get a formal response by the end of the second quarter.

The company is also pursuing a strategic sales channel and alliance through a CFA with China’s top tier boiler company Jiangsu Shuang Liang Boiler Co. Ltd, a subsidiary of China’s Shuang Liang Group Co. Ltd, which is one of China’s top 500 enterprises. Shuang Liang Boiler Company has the largest market share and ranks as China’s number one boiler manufacturer in the industrial boiler, district heating boiler, and commercial and institutional boiler markets, with over 700 active sales personnel and sales offices strategically located throughout China. The company has been developing a relationship with Shuang Liang Boiler company now for some time, leading to their participation in the formal burner the testing process.

“I am delighted to make public that we have successfully produced, installed, commissioned, and brought into full operation our fire tube “ClearSign Core” Ultra Low NOx burner in a commercial fire tube boiler in China, and were able to arrange for the Chinese government testing authorities to conduct and complete their rigorous burner product tests,” said Jim Deller Ph.D., Chief Executive Officer of ClearSign.  “This is another major milestone for the company, and we believe this demonstration met all requirements.  Prior to this testing we submitted all the required documentation, the acceptance of which enabled the performance testing to proceed.  I do need to note that we do still need to wait for a response from the government officials, but we are very optimistic that this will be positive.  For anyone not aware, the Chinese government burner “type” testing is mandatory for boiler burners, and, if granted, and our formal Government burner product certification is issued it will certify that our 125hp ClearSign Core fire tube Burner is a commercially approved production ultra-low NOx burner model, and accordingly is allowed to be produced, marketed and sold in the China market.”

“Concurrently we have been developing our strategic relationship with Shuang Liang Boiler company now for some time, and in-fact they provided the fire tube boiler, resources, personnel and secure facilities needed for our demonstration fire tube burner. This relationship has progressed and is now evidenced in our collaboration agreement describing our mutual plans to create and sell a range of integrated boilers and ClearSign Core burners to sell into the Chinese market,” concluded Dr. Deller.
