A preliminary reading: How is a confirmation email sent on an order placement?

1. Magento\Sales\Model\Order\Email\Sender\OrderSender::prepareTemplate()

magento/magento2/blob/2.1.5/app/code/Magento/Sales/Model/Order/Email/Sender/OrderSender.php#L114-L140


/**
 * Prepare email template with variables
 *
 * @param Order $order
 * @return void
 */
protected function prepareTemplate(Order $order)
{
    $transport = [
        'order' => $order,
        'billing' => $order->getBillingAddress(),
        'payment_html' => $this->getPaymentHtml($order),
        'store' => $order->getStore(),
        'formattedShippingAddress' => $this->getFormattedShippingAddress($order),
        'formattedBillingAddress' => $this->getFormattedBillingAddress($order),
    ];
    $transport = new \Magento\Framework\DataObject($transport);


    $this->eventManager->dispatch(
        'email_order_set_template_vars_before',
        ['sender' => $this, 'transport' => $transport]
    );


    $this->templateContainer->setTemplateVars($transport->getData());


    parent::prepareTemplate($order);
}

2. Magento\Sales\Model\Order\Email\Sender\OrderSender::getPaymentHtml()

magento/magento2/blob/2.1.5/app/code/Magento/Sales/Model/Order/Email/Sender/OrderSender.php#L142-L154


/**
 * Get payment info block as html
 *
 * @param Order $order
 * @return string
 */
protected function getPaymentHtml(Order $order)
{
    return $this->paymentHelper->getInfoBlockHtml(
        $order->getPayment(),
        $this->identityContainer->getStore()->getStoreId()
    );
}

3. Magento\Payment\Helper\Data::getInfoBlockHtml()
